Merge/Overlay two charts

[dmantamp]

Hi All,
Can anybody help me to in finding a sample code to merge two charts with same datataset. For example, I have a bar chart and a TimeSeries. I want to show it overlayed. Please help me.

Thanks

If the solution in CombinedDomainCategoryPlot demo does not satisfy you (having a bar chart below, and time series above) then one way is to use JLayeredPane.

You would then add the two JFreeCharts to the panel, one below and other with a transparent background above... something like:

Code: Select all

lLayeredPane.add(barPlotChart, new Integer(0));
 lLayeredPane.add(timeSeriesChart, new Integer(1));	

And make sure that the background of the time series is transparent with:

Code: Select all

timeSeriesChart.setOpaque(false);
timeSeriesChart.setBackground(new Color(0, 0, 0, 0));

JFreeChart also supports multiple charts in the same ChartPanel, which is like overlaying. The added benefit is that zooming will zoom in on both charts at the same time. http://www.jfree.org/phpBB2/viewtopic.p ... 883#p77685
