I'm trying to create an overlaidchart with months as X axis (TimeSeries) and a certain value as Y axis.
The point is that right now I dont know how to set a margin between the columns of different months (xyverticalbar plot) (they all appear one after the other without any space).
Thanks in advance
You'll need a chartpostprocessor and take a look at the jfc apis at www.jfree.org
