The original version of this blog entry can be found at http: The background image is added with the following code, which specifies the image and how it should be resized to fit the background obviously the image is coming from a file on my desktop, so you should not use this code without modifying the image source: Both programs generate the chart in SVG format 1, times during a “warm-up” phase, then a further 1, times during the testing phase.

I just released a new version of Orson Chartsa 3D chart library for the Java platform. So buy the guide, and help keep JFree alive!
