Without a small snippet of code that reproduces the problem, not really. 
If you can create a self-contained test that demonstrates the problem, I 
can take a look at it.

However, if one of axis is a CategoryAxis, then performance is horrible. I think the problem is CategoryAxis creates a tick for each one of 10000+ strings. I already tried to set tick visibility to false, which help a bit, but still too slow. Is there anyway to improve this?
