addValueClickHandler(ValueClickHandler handler)
Fires when a data value is clicked, and provides information about the data value that was clicked as a
DrawnValue object. |
com.google.gwt.event.shared.HandlerRegistration addValueClickHandler(ValueClickHandler handler)
DrawnValue
object. Specifically, this fires for clicks on pie slices, bars or columns, areas, lines or points (in a 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.
