Method Detail

addValueClickHandler

com.google.gwt.event.shared.HandlerRegistration addValueClickHandler(ValueClickHandler 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 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 getNearestDrawnValue() to discover the nearest data values.

Parameters:

handler - the valueClick handler

Returns:

HandlerRegistration used to remove this handler
