Hi.
Trying to use JFreeChart for viewing stats, it's quite nice BUT, very very slow.
on a good Solaris machine, it takes 5 secondes to get the PNG file generated for a 800x500 graphic.
Any clue to accelerate it ?
Thanks.

Re: Performances
Generating JPG is quite more speed : 1 second only ....
but
PNG -> 15 ko
JPG -> 60 ko.

Hi Philippe,
It sounds like the PNG encoder that I've included with JFreeChart (on the basis that it shares the same license, the LGPL) might not be so fast. You might try some third-party encoders, or look at what is provided in the Sun imaging libraries (which I haven't investigated yet). I'd be interested to hear which encoders perform the best.
