Hi!!

You have to create an XYPlot object from your JFreeChart object using the getXYPlot() method and then use the method: setSeriesPaint(java.awt.Paint[] paint) to change the color of the lines.

It will look like:

myXYPlot = myJFreeChart.getXYPlot();
myXYPlot.setSeriesPaint(new Paint[] {Color.red, Color.green, Color.blue});

Hi again!!!

Sorry!!!

It isn't a XYPlot. Your chart has a CategoryPlot (or something like this). Try to change the method getXYPlot() by getDataset().

It will look like:

myPlot = myJFreeChart.getDataset();
myPlot.setSeriesPaint(new Paint[] {Color.red, Color.green, Color.blue});

Thanks for your help !

Exactly, my chart has a CategoryPlot I try to do something like:

CategoryPlot cPlot = chart.getCategoryPlot();
cPlot.setSeriesPaint(new Paint[] {Color.red, Color.green, Color.blue});

and It´s working!!!!

thanks again
