addChartBackgroundDrawnHandler(ChartBackgroundDrawnHandler handler)
Called when most elements of the chart other than data data have been drawn, including gradations and legend.

fireEvent
HandlerRegistration addChartBackgroundDrawnHandler(ChartBackgroundDrawnHandler handler)
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.
