I have this chart produced by jfreechart's stackedareachart. The label's on the x axis are the months of the year. I need to be able to display every other label. Something like:
Jan Mar Apr Jun Aug Oct Dec

I am able to do this when the Domain Axis is a NumberAxis, but I can't figure it out because the stackedareachart uses a CategoryAxis for the domain Axis. CategoryAxis doesn't have a set tick mark interval method.
What can I do to display a subset of labels?
