Improving Image quality

Post by kds_kuldeep » Sun Jun 15, 2008 5:46 pm

Hi,

We are able to successfully generate the charts but we are facing problem giving good quality image output.Currently we are using PNG type.

Can changing image type will help.
We want to improve the sharpness of labels as currently they are blur.
Also I am displaying labels in X axis at certain angle and this is making them worst.

IS IT possible to have bigger size of charts we currently our best resolution is with 500*300 pixels which is very small as per our data.

Please help us improving quality and size of images.

Increase the maximum draw height and width of the ChartPanel since the image is scaled beyond that size. There have been numerous conversations on the forum on techniques to improve image quality. I found several by searching the forum.
