JFreeChart Performance Guide

Post by Sourcemaker » Sun Jul 16, 2006 1:58 pm

Hi Guys,

is there any documentation available,
how I can improve the performance of JFreeChart ?

For example, the image encoder takes a lot of time for
rendering / encoding the charts into png images.

Is there any way out ?

Thanks

slow with JDK 1.3 but
with 1.4, it uses the JDK's ImageIO, so it's the best you can do.

the larger your image is, the longer it takes.
generating 1024*768 images takes far less than a seconds.
rendering it on a browser takes more time.
