Method Details

addChartBackgroundDrawnHandler
Called when most elements of the chart other than data data have been drawn, including gradations and legend.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 variousDrawItem
s, you should do in response to this notification. Due to auto-sizing, APIs that are typically used to position custom DrawItems (such asgetChartLeft()
) 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.- Parameters:
