- - ### Method Detail

    - #### onValueClick

          void onValueClick(ValueClickEvent event)

      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.

      Parameters:
        `event` - the event
