RE: [jCharts-users] Gradient on each bar rather than across entire graph

[Chris M. <ch...@de...>]

You could probably do this with a custom renderer. It would be actioned on
every bar drawn though.

So for instance I changed the color of a line point if it fell within a
certain range with a PreAxisValueRenderListener.

	public void preRender( AxisValueRenderEvent axisValueRenderEvent )
	{
			//---keep the current paint around
			Paint currentPaint=
axisValueRenderEvent.getGraphics2D().getPaint();
                  axisValueRenderEvent.getGraphics2D().setPaint(
this.forecastPaint );

                  // overwrite color if range test
                  double value =
axisValueRenderEvent.getiAxisChartDataSet().getValue(
axisValueRenderEvent.getDataSetIndex(), axisValueRenderEvent.getValueIndex()
);
                  if (value > loRange && value < hiRange) {
                            axisValueRenderEvent.getGraphics2D().setPaint(
this.inRangePaint );
                  }
            
			//---reset the current Paint
			axisValueRenderEvent.getGraphics2D().setPaint(
currentPaint );
		}
	}
