It's a bug caused by trying to draw a Shape with very large coordinates in Java 2D. A suggested workaround posted in the Java bug database is to "implement your own clipping algorithms". I haven't attempted that yet!

Try something like this:

Code: Select all

CategoryPlot plot = chart.getCategoryPlot();

plot.getRenderer().setSeriesPaint(0, new Color(0, 0, 255));
plot.getRenderer().setSeriesPaint(1, new Color(75, 75, 255));
plot.getRenderer().setSeriesPaint(2, new Color(150, 150, 255));

Re: XYchart tooltip and Mouseevent

1- when I put the mouse on a point in the XY chart I get a tool Tip which shows the X Y coordinates. I am dealing with very small numbers (up to 10 decimal places) and Jfreechart seems to round these numbers in the tool tip and hence I always get x:0 , y:0 . How can I increase the precision of thes...

That class is in the jfreechart-0.9.6.jar file, so something must be wrong with your classpath setup.

Here is the link you are after:

I'm not sure how easy it will be to implement a workaround if you have no control over your server.

Click on the chart with the right mouse button and select 'Print...', the code that handles this is all in the ChartPanel class.
