Hi!!

How can I draw grid lines with JFreeChart???
I need to plot a line chart (representing heart beats) but the background must be divided in squares like in a cardiogram.
How can I create this background, I mean, the squares in JFreeChart??

Thanks!!

The solution :

Code: Select all

        plot.setDomainGridlinePaint(Color.black);
        plot.setRangeGridlinePaint(Color.black);
