  Can be used directly, or specified as `ListGrid.chartConstructor` or `CubeGrid.chartConstructor`.

  NOTE: you must load the Drawing and Charts `Optional Modules` before you can use FacetChart. Also, the Charts Module is available in Pro Edition or better, please see smartclient.com/product for licensing information.

  To create a FacetChart, set `facets` to an Array of Facet objects describing the chart dimensions and `valueProperty` to value field name. For example:

        // Creating data
        Record sprRec = new Record();
        sprRec.setAttribute("season", "Spring");
        sprRec.setAttribute("temp", "79");
        Record sumRec = new Record();
        sumRec.setAttribute("season", "Summer");
        sumRec.setAttribute("temp", "102");
        Record autRec = new Record();
        autRec.setAttribute("season", "Autumn");
        autRec.setAttribute("temp", "81");
        Record winRec = new Record();
        winRec.setAttribute("season", "Winter");
        winRec.setAttribute("temp", "59");

        // Creating chart
        FacetChart chart = new FacetChart();
        chart.setFacets(new Facet("season", "Season"));
        chart.setValueProperty("temp");
        chart.setData(new Record[]{sprRec, sumRec, autRec, winRec});
        chart.setTitle("Average temperature in Las Vegas");

  The following SDK examples demonstrate charts with a single facet:

  - Log Scaling example,
  - Interactive Data Points example, and
  - Adding Element example.
  See the following SDK examples for examples of charts with multiple facets:
  - Simple Chart example,
  - Multi-Series Chart example, and
  - Dynamic Data example.

  ### the Inlined Facet

  Having an "inlined facet" is another method to provide data to the chart. In this case each CellRecord contains multiple data values; one facet definition is considered "inlined", meaning that the facetValueIds from this facet appear as properties in each Record, and each such property holds one data value. In this case the singular `valueProperty` is ignored. For example:

        // Creating data
        CellRecord lvRec = new CellRecord();
        lvRec.setAttribute("spring", "79");
        lvRec.setAttribute("summer", "102");
        lvRec.setAttribute("autumn", "81");
        lvRec.setAttribute("winter", "59");

        // Creating inlined facet
        Facet inlinedFacet = new Facet();
        inlinedFacet.setInlinedValues(true);
        inlinedFacet.setValues(
                new FacetValue("spring", "Spring"),
                new FacetValue("summer", "Summer"),
                new FacetValue("autumn", "Autumn"),
                new FacetValue("winter", "Winter")
        );

        // Creating chart
        FacetChart chart = new FacetChart();
        chart.setFacets(inlinedFacet);
        chart.setData(new Record[]{lvRec});
        chart.setTitle("Average temperature in Las Vegas");

  Example with two facets:

        // Creating data
        CellRecord lvRec = new CellRecord();
        lvRec.setAttribute("city", "Las Vegas");
        lvRec.setAttribute("spring", "79");
        lvRec.setAttribute("summer", "102");
        lvRec.setAttribute("autumn", "81");
        lvRec.setAttribute("winter", "59");
        CellRecord nyRec = new CellRecord();
        nyRec.setAttribute("city", "New York");
        nyRec.setAttribute("spring", "60");
        nyRec.setAttribute("summer", "83");
        nyRec.setAttribute("autumn", "66");
        nyRec.setAttribute("winter", "40");

        // Creating inlined facet
        Facet inlinedFacet = new Facet();
        inlinedFacet.setInlinedValues(true);
        inlinedFacet.setValues(
                new FacetValue("spring", "Spring"),
                new FacetValue("summer", "Summer"),
                new FacetValue("autumn", "Autumn"),
                new FacetValue("winter", "Winter")
        );

        // Creating chart
        FacetChart chart = new FacetChart();
        chart.setFacets(inlinedFacet, new Facet("city", "City"));
        chart.setData(new Record[]{lvRec, nyRec});
        chart.setStacked(false);
        chart.setTitle("Average temperatures");

  ### Dual axis or multi-axis charts

  FacetChart supports drawing multiple vertical axes. This is commonly used to show values with different units (for example: sales in dollars, total units shipped) and/or very different ranges (for example: gross revenue, profit) on the same chart. Each set of values, referred to as a "metric", gets its own axis and gradation marks.

  To use multiple axes, you add an additional facet called the "metric facet" that specifies each axis to be plotted as a facetValueId. The metric facet is an inlined facet, so as with inlined facets in general, each CellRecord has a value for each facetValueId of the metric facet. You then set `extraAxisMetrics` to the list of metrics that should be plotted as additional axes.

  For example, if you were plotting revenue and profit for each month of the year, you would have one facet named "metric" with facetValueIds "revenue" and "profit" and a second facet "month". Each CellRecord would have the revenue and profit for one month, stored under the properties "revenue" and "profit". Setting `extraAxisMetrics` to ["profit"] would cause profit to be plotted as the second axis. See the Dual Axis SDK sample for an example.

  You can have multiple extra axes and the additional axes and gradation tics will be drawn at increasing distances from the chart. By default, the first metric is drawn as a column chart and subsequent metrics are drawn as lines; you can override this via `extraAxisSettings`. See the 3+ Axes SDK sample for an example of multiple extra axes.

  Multi-axis, multi-facet charts are also allowed. Extending the previous example, you might add a new facet "company", for a total of 3 facets. Each CellRecord would have "revenue" and "profit" for one combination of "company" and "month". The default appearance in this case would show revenue as clustered columns (one cluster per month, one column per company) and would show profit as multiple lines (one per company). See the Multi-Series SDK sample for an example of a multi-axis, multi-facet chart.

  ### Mixed plots

  In some cases you want to show some data series as one shape and other data series as another shape but use the same axis. This is commonly used when one series is of a fundamentally different kind than the other series (for example, a projection or average) but still has the same scale.

  To achieve a mixed plot like this, define it as a multi-axis chart as explained above, but set `MetricSettings.showAxis` false to avoid a second axis appearing, and set `MetricSettings.matchGradations` to cause the same gradations to be used for both plots.

  See the Mixed Plots SDK example.

  ### Scatter Charts

  Scatter charts differ from other chart types in that both axes represent continuous numeric data rather than a discrete set of facet values (like months of the year). For this reason Scatter charts use the same concept of a "metric" facet as is used by Dual-Axis charts, where the metric facet is expected to have exactly two metrics: the `xAxisMetric` and `yAxisMetric`.

  Unlike all other chart types, a scatter plot may be specified with only the metric facet. However one additional facet can be defined, which allows multiple sets of x,y points to be drawn in different colors, analogous to the different colors of a multi-series line chart.

  See the Scatter Plot SDK example.

  Date values on the X axis

  FacetChart also supports scatter charts where the x-axis represents date- or time-valued data and the y-axis represents numeric data, as normal. To enable this mode all records in the data must have values for the facetValueId of the `xAxisMetric` that are true Date objects, not Strings or `null`s. For these charts, vertical lines are drawn to represent a sequence of significant datetime values on the x-axis, such as the first day of the month or week. The mechanism used to select these Dates and format them into the x-axis labels is the same mechanism used by charts with `labelCollapseMode` set to "time".

  ### Bubble Charts

  A "bubble" chart is a type of scatter chart where the size of each rendered data point represents an additional metric value, allowing 3 continuous data values to be visualized together. When using `chartType:"Bubble"`, the additional metric is configured via `pointSizeMetric`. Points will be sized between the `minDataPointSize` and `maxDataPointSize`, optionally with `logarithmic scaling`. A legend will be included showing how point size represents data values, and a multi-facet Bubble chart can optionally use a different shape for each `facetValue` via `useMultiplePointShapes`.

  Variable-size points can also be used with other, non-scatter chart types (such as "Line" or "Radar") when `showDataPoints` is enabled, by setting `pointSizeMetric` to the `FacetValue.id` of a `facetValue` of the metric facet. In this case, a legend for point sizes is not shown by default, but can be enabled via `showPointSizeLegend`.

  Whenever drawing variable size data points, by default, the largest data points are drawn first so that smaller data points are less likely to be completely occluded by larger data points, but this can be disabled by setting `autoSortBubblePoints` to `false`. Visual appearance of data points can be further customized by setting the `bubbleProperties`.

  See the Bubble Chart SDK example.

  ### Color Scale Charts

  FacetChart supports rendering an additional metric value as the color of each data point. This feature requires that `showDataPoints` be enabled and is configured via `colorScaleMetric`. Instead of data points being drawn using a separate color for each `facetValue` of the legend facet, the data points will be drawn using a color interpolated between the `scaleStartColor` and `scaleEndColor`, optionally with `logarithmic scaling`. A legend is included by default via `showColorScaleLegend` that shows how the data values are mapped to a color via a gradient over the range of colors used in the chart. Visual appearance of data points in color scale charts can be further customized by setting the `bubbleProperties`, just as with bubble charts.

  Note that when color is being used to show values of the `colorScaleMetric` then color cannot be used to distinguish between different `facetValues`. Therefore color scale charts cannot have a (non-metric) legend facet.

  See the Color Scale Chart SDK example.

  ### Notes on printing

  FacetCharts support printing on all supported desktop browsers. When using Pro Edition or better with the Smart GWT Server Framework installed, charts can also be exported to PDF via `RPCManager.exportContent()` or to images via `RPCManager.exportImage()`.

                               throws java.lang.IllegalStateException

      End value for the primary axis of the chart.

      If set to an explicit value, this will be respected. If unset, the axis end value will default to a value large enough to the largest data point, rounded up to the nearest (next) gradation.

      For multi-axis charts, Bubble charts, and Scatter charts, the `facetChart.axisEndValue` affects only the first axis of the chart. End values for other axes of multi-axis charts can be set on a per-axis basis via `MetricSettings.xAxisEndValue`. For Scatter charts, the `xAxisEndValue` property must be used to set the end value of the x-axis.

      Note that if this chart's data includes points that fall above this value, they are ommitted and effectively treated as null values. For charts showing a data line, developers may wish to set `discontinuousLines` to true in this case.

      Parameters:
        `axisEndValue` - Default value is null
      Throws:
        `java.lang.IllegalStateException` - this property cannot be changed after the component has been created

      Start value for the primary axis of the chart.

      If set to an explicit value, this will be respected. If unset, the axis start value will default to 0, or to a value that makes good use of vertical space based on `minDataSpreadPercent`.

      For multi-axis charts, Bubble charts, and Scatter charts, the `facetChart.axisStartValue` affects only the first axis of the chart. Start values for other axes of multi-axis charts can be set on a per-axis basis via `MetricSettings.axisStartValue`.

      Defines the set of metrics that will be plotted as additional vertical axes. See the main `FacetChart` docs for an overview of how multi-axis charts are used.

      Each metric corresponds to different value property of the data records and superimposes its drawn data onto the chart rectangle. The value properties are called metrics, and they can be either the `valueProperty` or the "id" of a `FacetValue` of the inlined `Facet` (which is then called the metric facet). Each value axis has its own gradations that are shown as tick marks along the length of the axis. This property, extraAxisMetrics, specifies the metrics to use for additional value axes to the main value axis.

      The additional value axis may have their own gradations, chart type, log scale, data colors and gradients, and other chart properties. These properties are specified with the `extraAxisSettings` property.

      Value axes, including the main value axis, are labelled in the legend along with representations of the charted data. The labels are taken from the `FacetValue.title` of each metric's FacetValue (or the `valueTitle` if the metric is the `valueProperty`).

      The order of the metrics determines the position of the corresponding axes on the chart as well as the z-ordering of the corresponding data lines. The first and second extra value axes are placed to the right of the chart rectangle, and any remaining extra value axes are placed to the left of the main value axis (and therefore to the left of the chart rectangle).

      Parameters:
        `extraAxisMetrics` - Default value is []
      Throws:
        `java.lang.IllegalStateException` - this property cannot be changed after the component has been created

    - #### getExtraAxisMetrics

          public java.lang.String[] getExtraAxisMetrics()

      For charts will multiple vertical axes, optionally provides settings for how each `extra axis metric` is plotted. See the main `FacetChart` docs for an overview of how multi-axis charts are used.

      The chart of each metric's values may be of any rectangular chart type that uses a vertical value axis ("Column", "Area", and "Line"). Because the charts will be superimposed over the same drawing area, there can only be one "Column" chart and one "Area" chart. The column chart is placed on the bottom followed by the area chart, and then the line charts are drawn on top in the order of their metric in the `extraAxisMetrics` array. If the `chartType`s are left unspecified then by default the first metric will be drawn as columns and the remaining will be drawn as lines.

      Parameters:
        `extraAxisSettings` - Default value is []
      Throws:
        `java.lang.IllegalStateException` - this property cannot be changed after the component has been created

      - the "inlinedValues" property can be set on a facet to change data representation as described under Chart.data.
      - for a non-inlined facet, Charts support auto-derivation of facetValues from the data.

      In all chart types except "Bubble" and "Scatter", the chart displays a value for each discrete value of one facet (i.e. single-facet charts) or it displays a value for each combination of discrete values of two facets (multi-facet charts). The two discrete facets are the `data label facet` and the `legend facet`. They are named based on where the `values` of the facet appear in the chart. The facet whose values are rendered as labels along the data axis or in the main chart area is the data label facet, and the facet whose values are rendered in the legend is the legend facet.

      For single-facet charts, most chart types have a data label facet as the first facet but no legend facet. Single-facet Pie charts have a legend facet as the first facet but no data label facet. Bubble and Scatter plots may have a legend facet as the second facet, after the metric facet.

      In all multi-facet charts, the data label facet is always first and the legend facet is second. In most chart types the data label facet and the legend facet may be swapped on the fly by the user clicking on the "Swap Facets" item of the context menu.

      Parameters:

                                    throws java.lang.IllegalStateException

      What to do when there are too many data points to be able to show labels for every data point at the current chart size - see `LabelCollapseMode`.

      Each of the possible strategies is re-applied when the user resizes the chart as a whole, so if labels are omitted the user can make them visible via resize or zoom.

      If the labelCollapseMode is "numeric" then vertical lines will be drawn at gradation values automatically chosen by the chart.

      If the labelCollapseMode is "time" then vertical lines are drawn to represent a sequence of significant datetime values on the x-axis, such as the first day of the month or week. The chart automatically chooses the sequence of Dates such that the spacing between them expresses the smallest granularity of time possible while still allowing the axis labels to make good use of the space. If, for example, the Date values in the data span a few years in time then the chart may select January 1 of the same year of the earliest data point and every January 1 thereafter (in range of the data) as the sequence of Dates and label each Date by the four-digit year. If the time span of the data values is on the order of minutes then the chart may select multiples of 15 minutes as the seqeunce of Dates. FacetChart currently supports the following granularities of time: years, quarters, months, weeks, days, hours, half-hours, quarter-hours, 5 minutes, minutes, 30 seconds, and 15 seconds.

      The format of the Date labels is fixed by FacetChart. In particular, the `format` method for any setter applied with `setXAxisValueFormatter()` will not be called on values for the x-axis. However, FacetChart uses the `global array of abbreviated month names` for the time granularities of quarters, months, and weeks, uses the `default short time format` to format labels for time granularities from minutes to hours, and uses the `default time format` to format labels for the time granularities of 15 seconds and 30 seconds. The label format can be customized by changing these three formatters. Also note that for the time granularity of weeks the sequence of Dates will be the first day of each week, as specified by `com.smartgwt.client.util.DateUtil#setFirstDayOfWeek()`.

      Note that if the labelCollapseMode is "time" or "numeric" then the `data` must be initially sorted with the `data label facet`'s values in ascending order.

      Parameters:
        `labelCollapseMode` - Default value is null
      Throws:
        `java.lang.IllegalStateException` - this property cannot be changed after the component has been created

                                       throws java.lang.IllegalStateException

      If all data values would be spread across less than `minDataSpreadPercent` of the axis, the start values of axes will be automatically adjusted to make better use of space.

      For example, if a column chart has all data values between 500,000 and 500,100, if the axis starts at 0, differences in column heights will be visually indistinguishable. In this case, since all data values appear in well under 30% of the axis length, the default `minDataSpreadPercent` setting would cause the axis to start at a value that would make the column heights obviously different (for example, starting the axis as 500,000).

      Setting an explicit `axisStartValue` or `axisEndValue`, disables this behavior, as does setting `minDataSpreadPercent` to 0.

      For multi-axis charts, use `MetricSettings.minDataSpreadPercent` for per-axis settings.

      For Bubble and Scatter charts, `minDataSpreadPercent` affects only the y-axis of the chart. The property `minXDataSpreadPercent` must be used to enable the corresponding feature for the x-axis.

      Parameters:
        `minDataSpreadPercent` - Default value is 30
      Throws:
        `java.lang.IllegalStateException` - this property cannot be changed after the component has been created

          public int getMinDataSpreadPercent()

      If all data values would be spread across less than `minDataSpreadPercent` of the axis, the start values of axes will be automatically adjusted to make better use of space.

                                  throws java.lang.IllegalStateException

      For charts where `showDataPoints` is enabled, this property specifies an additional metric (i.e. an "id" of a metric facet value) that determines the size of the data points drawn. For example, when a circle is drawn to represent a data point then the size of the data point is the diameter of the circle, in pixels.

      The size is calculated by linearly scaling the value of the `pointSizeMetric` of the point between the `minDataPointSize` and `maxDataPointSize`. The data point that has the lowest value for the `pointSizeMetric` will be drawn as a shape `minDataPointSize` pixels in size, and the data point that has the highest value for the `pointSizeMetric` will be drawn as a shape `maxDataPointSize` pixels in size.

      Using a log-scale to calulate the size of the data points is achieved by enabling `logScalePointSize`.

      If the `ChartType` is `"Bubble"` then the default `pointSizeMetric` is `"pointSize"`.

      Note that setting `pointSizeMetric` to non-`null` implicitly enables `showDataPoints`.

      Parameters:
        `pointSizeMetric` - Default value is null
      Throws:
        `java.lang.IllegalStateException` - this property cannot be changed after the component has been created

    - #### addChartBackgroundDrawnHandler

          public com.google.gwt.event.shared.HandlerRegistration addChartBackgroundDrawnHandler(ChartBackgroundDrawnHandler handler)

      Add a chartBackgroundDrawn handler.

      Called when most elements of the chart other than data data have been drawn, including gradations and legend.

      This notification will be fired each time the chart is redrawn (due to resize, data change, etc). If you want to draw additional information on the chart using `DrawPane` (FacetChart's superclass) and various `DrawItem`s, you should do in response to this notification. Due to auto-sizing, APIs that are typically used to position custom DrawItems (such as `FacetChart.getChartLeft()`) may return bad values if called at other times.

      Additional DrawItems added in this method will appear underneath data elements such as bars or columns. See `FacetChart.chartDrawn()` for placing DrawItems on top of data elements.

      Specified by:
        `addChartBackgroundDrawnHandler` in interface `HasChartBackgroundDrawnHandlers`
      Parameters:
        `handler` - the chartBackgroundDrawn handler
      Returns:

      See `FacetChart.chartBackgroundDrawn()` for usage information.

      Specified by:
        `addChartDrawnHandler` in interface `HasChartDrawnHandlers`
      Parameters:
        `handler` - the chartDrawn handler
      Returns:

    - #### drawnValueContainsPoint

          public java.lang.Boolean drawnValueContainsPoint(DrawnValue drawnValue)

      Returns whether a given `DrawnValue` contains a point. The point's X and Y coordinates may be passed into this method, or, if unspecified, the coordinates used are the current mouse event coordinates.

      For Area, Bubble, Line, Radar, and Scatter charts, a DrawnValue is considered to contain a point if the Euclidean distance from the DrawnValue's center (`x`, `y`) to the point is less than `this.dataPointSize`. For Pie charts, the DrawnValue is considered to contain a point if the point is within the pie slice. Similarly, for Doughnut charts, the DrawnValue is considered to contain a point if the point is within the pie slice and not in the doughnut hole. For Bar and Column charts, the DrawnValue is considered to contain a point if the point is within the bar or column, respectively. Note that for stacked Bar and Column charts, the point must also be in the stacked portion as opposed to anywhere within the bar or column.

      Parameters:
        `drawnValue` - the DrawnValue to check. The DrawnValue must be a valid DrawnValue from this chart.
      Returns:
        true if the DrawnValue contains the point at the given X, Y coordinates (or current mouse event coordinates); false if the DrawnValue does not contain the point; null for invalid parameters.

    - #### getNearestDrawnValue

          public DrawnValue getNearestDrawnValue()

      Returns rendering information for the data value that is shown nearest to the passed coordinates, as a `DrawnValue` object.

      Passed X and Y coordinates should be relative to the FacetChart. If neither an X or Y coordinate is passed, both X and Y will use the current `Canvas.getOffsetX()` and `Canvas.getOffsetY()`.

      If called before `FacetChart.chartDrawn()`, logs a warning and returns null. For a chart with multiple vertical axes, returns the nearest point from the first metric only (see `FacetChart overview`). For scatter charts, returns a DrawnValue where the `value` is from the `y-axis metric`.

      To get the nearest DrawnValue only if it contains the given coordinates, you can either use the `getDrawnValueAtPoint()` API or call `drawnValueContainsPoint()` on the return value.

      Behavior for different chart types is as follows:

      #### Bar / Column

      Returns the centerpoint of the end of the nearest bar or column by considering the Y coordinate (bar) or X coordinate (column) only.

      #### Line / Area

      Returns the nearest point based on which data label is nearest to the passed X coordinate. For multi-series charts, if Y coordinate is not passed the data point returned is from the series that has the highest value at the data label.

      #### Radar

      Returns the data point nearest the passed coordinates by straight line distance. Passing only one coordinate will cause a warning to be logged and null to be returned; passing neither coordinate is allowed (`getOffsetX/Y` will be used).

      #### Pie

      Returns the data point for the segment that would be hit if a line were drawn from the passed coordinates to the center of the pie.

      If there are multiple stacked pies, uses the pie that contains the passed coordinates, otherwise the outermost pie.

      If there are multiple non-stacked pies, uses the pie that is nearest the passed coordinates by straight-line distance to the center of the pie.

      Passing only one coordinate will cause a warning to be logged and null to be returned; passing neither coordinate is allowed (`getOffsetX/Y` will be used).

      If the chart is a `multi-axis chart` then this method takes an optional parameter, `metric`, which causes this method to return a `DrawnValue` from the specified metric. If a metric is not passed then the first metric of the metric facet will be used (or just the `valueProperty` if there is no metric facet).

      Returns:
        the nearest drawn value, or null for invalid arguments / incorrect timing of call

      Returns rendering information for the data value that is shown nearest to the passed coordinates, as a `DrawnValue` object.

      Passed X and Y coordinates should be relative to the FacetChart. If neither an X or Y coordinate is passed, both X and Y will use the current `Canvas.getOffsetX()` and `Canvas.getOffsetY()`.

      Parameters:
        `value` - the value to be drawn.
      Returns:
        the X coordinate where the passed data value would be drawn; or null if the passed `FacetValueMap` does not identify a currently-drawn data cell.

    - #### addLegendClickHandler

          public com.google.gwt.event.shared.HandlerRegistration addLegendClickHandler(LegendClickHandler handler)

      Add a legendClick handler.

      Fires when the user clicks on the legend area of the chart.

      If the user specifically clicks on a color swatch or it's label, the `FacetValue` clicked on will be provided.

      If the chart is a `multi-axis chart`, the `FacetValue` for the clicked-on metric will also be provided.

      Specified by:
        `addLegendClickHandler` in interface `HasLegendClickHandlers`
      Parameters:
        `handler` - the legendClick handler
      Returns:
        `HandlerRegistration` used to remove this handler

    - #### addLegendHoverHandler

          public com.google.gwt.event.shared.HandlerRegistration addLegendHoverHandler(LegendHoverHandler handler)

      Add a legendHover handler.

      Fires when the mouse hovers over a color swatch or its label in the legend area of the chart.

      The `FacetValue` that the user is hovering over is provided. If the chart is a `multi-axis chart`, the `FacetValue` for the hovered-over metric will also be provided.

      Specified by:
        `addLegendHoverHandler` in interface `HasLegendHoverHandlers`
      Parameters:
        `handler` - the legendHover handler
      Returns:
        `HandlerRegistration` used to remove this handler

    - #### addValueClickHandler

          public com.google.gwt.event.shared.HandlerRegistration addValueClickHandler(ValueClickHandler handler)

      Add a valueClick handler.

      Fires when a data value is clicked, and provides information about the data value that was clicked as a `DrawnValue` object.

      Specifically, this fires for clicks on pie slices, bars or columns, areas, lines or points (in a Bubble or Scatter plot).

      If there are multiple data values at the clicked position, you can use `FacetChart.getNearestDrawnValues()` to discover the full list of values at the current coordinate (pass in `getOffsetX/Y()` for the coordinates).

      If you want to create behaviors for clicking or moving near shapes without requiring a direct hit, implement a standard `Canvas.click()` handler on the FacetChart as a whole and use `FacetChart.getNearestDrawnValue()` to discover the nearest data values.

      Specified by:
        `addValueClickHandler` in interface `HasValueClickHandlers`
      Parameters:
        `handler` - the valueClick handler
      Returns:
        `HandlerRegistration` used to remove this handler

      For a `zoomed chart`, simultaneously sets the `zoomStartValue` and `zoomEndValue`.
      Parameters:
        `startValue` - starting value for the data range shown in the main chart
        `endValue` - ending value for the data range shown in the main chart

    - #### setDefaultProperties

          public static void setDefaultProperties(FacetChart facetChartProperties)

      Class level method to set the default properties of this class. If set, then all existing and subsequently created instances of this class will automatically have default properties corresponding to the properties set on the SmartGWT class instance passed to this function before its underlying SmartClient JS object was created. This is a powerful feature that eliminates the need for users to create a separate hierarchy of subclasses that only alter the default properties of this class. Can also be used for skinning / styling purposes.

      Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.

      Parameters:
        `facetChartProperties` - properties that should be used as new defaults when instances of this class are created
      See Also:
        `SGWTProperties`

    - #### setData

          public void setData(Record[] records)

      Dataset for this chart.

      Data should be specified as an array of Records where each record contains one data value. Each record also contains a property named after each facetId whose value is a facetValueId from that facet.

      For example, with a facet with id "regions" and facetValues "west", "north" and "east", and with `valueProperty` with it's default value "_value", the `data` property could be:

              isc.Chart.create({
                 facets:[{ id:"regions"
           }],
                 data : [
                    {regions:"west", _value:4},
                    {regions:"north", _value:2},

           {regions:"east", _value:5}
                 ]
              })

      If there were a second facet with id "product" and facetValues "cars" and "trucks", a Chart with a complete set of values would be:

           isc.Chart.create({
                 facets:[{ id:"regions" }, { id:"product" }],
                 data : [

           {product:"cars", regions:"west", _value:4},
                    {product:"cars", regions:"north", _value:2},

           {product:"cars", regions:"east", _value:5},
                    {product:"trucks", regions:"west", _value:1},

           {product:"trucks", regions:"north", _value:9},
                    {product:"trucks", regions:"east", _value:3}

           ]
              })

      This 2 facet (or "2 dimensional") dataset, if rendered as a bar chart, would use stacked or clustered bars and a legend.
      Parameters:
        `data` - data Default value is null

      Parameters:
        `dataLabelHoverHTMLCustomizer` -

    - #### setLegendHoverCustomizer

          public void setLegendHoverCustomizer(LegendHoverCustomizer legendHoverHTMLCustomizer)

      The +link{FacetValue} that the user is hovering over is provided. If the chart is a +link{facetChart.extraAxisMetrics,multi-axis chart}, the +link{FacetValue} for the hovered-over metric will also be provided.

      Parameters:
        `facetValue` - (FacetValue) facetValue that the mouse is over
        `metricFacetValue` - (FacetValue) for a multi-axis chart, facetValue representing the hovered-over metric. Null if chart is not multi-axis

    - #### setPointClickHandler

          public void setPointClickHandler(ChartPointClickHandler handler)

                                               PrintHTMLCallback callback)

      Retrieves printable HTML for this component and all printable subcomponents.

      By default any Canvas with children will simply collect the printable HTML of its children by calling getPrintHTML() on each child that is considered `printable`.

      If overriding this method for a custom component, you should either return a String of printable HTML string directly or return null, and fire the callback (if provided).

      To return an empty print representation, return an empty string ("") rather than null.

      The `printProperties` argument, if passed, must be passed to any subcomponents on which `getPrintHTML()` is called.

      Notes on printing

      To print a `FacetChart` for export on IE8 and earlier, it is `PrintProperties` with `printForExport`:true:

           final PrintProperties pp = new PrintProperties();
           pp.setPrintForExport(true);
           final String exportHTML = chart.getPrintHTML(pp, null);

      Note: this is an override point.

      Overrides:
        `getPrintHTML` in class `DrawPane`
      Parameters:
        `printProperties` - properties to configure printing behavior - may be null.
        `callback` - optional callback to fire. Generated HTML should be passed to the `PrintHTMLCallback.setHTML(String)` method of the callback.
      Returns:
        null if the print HTML is being generated asynchronously and/or a callback is provided; otherwise, the direct print HTML for this component (but note that returning direct print HTML is a deprecated feature).

      The value provided should be a value in the range of the facet for the X axis, for example, for a time-based axis, a Date instance, for a numeric axis, a Number, for an axis that just has text labels (such as city names), a String.
      If this method is called after the component has been drawn/initialized: Setter for `zoomStartValue`.

      Note that the `zoomStartValue` and `zoomEndValue` may be set simultaneously using `FacetChart.zoomTo`.

      Parameters:
        `zoomStartValue` - New start value for the data range shown in the main chart. Default value is null

      Returns:
        Object

    - #### setZoomEndValue

          public void setZoomEndValue(java.lang.Object zoomEndValue)

      For a `zoomed chart`, end value of the data range shown in the main chart. If `zoomStartValue` is not also set, the range shown will be from the beginning of the dataset up to `zoomEndValue`

      If this method is called after the component has been drawn/initialized: Setter for `zoomEndValue`.

      Note that the `zoomStartValue` and `zoomEndValue` may be set simultaneously using `FacetChart.zoomTo`.

      Parameters:
        `zoomEndValue` - New end value for the data range shown in the main chart. Default value is null

    - #### getZoomEndValue

          public java.lang.Object getZoomEndValue()

    - #### setXAxisValueFormatter

          public void setXAxisValueFormatter(ValueFormatter formatter)

      Formatter to apply to values displayed in the gradation labels on the x-axis. Some documentation directing here may also relate to `setYAxisValueFormatter()`.

      Note that the installed formatter will only be called if the x-axis has gradation labels, meaning labels drawn at regular intervals not associated with any particular facet value. So, it will not be called if the labels on the x-axis are merely facet value ids. In that case, you may wish to build an array of `FacetValues` for the x-axis facet, as a FacetValue constructor is available to set a separate facet id and title, and then call `Facet.setValues()`.

      Parameters:
        `formatter` - Formatter to apply to values displayed in the gradation labels

    - #### setYAxisValueFormatter

          public void setYAxisValueFormatter(ValueFormatter formatter)
