HandlerRegistration addValueClickHandler(ValueClickHandler handler)
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.
