Preventing JFreeChart from stretching the Chart

[Harry Plotter ;-)]

Hello everybody,

my problem is the following:

As the chartpanel gets not enough space for drawing, the labels for the description of chart are stretched.

Here is a picture, where you can see my decribed problem:


Does anybody know how to prevent JFreeChart doing this stretching without giving more space for the chartPanel?

Thanks for your help!
