if your data are within excel, why just not do it with Excel ??
easyer ...

how do you read it ?
using POI ?

you 'd better not save the chart.

have a close look at this

using Java headless capability, included starting jdk 1.4

launch your JVM with -Djava.awt.headless=true, it will use internal java code only, not the OS rendering system.

the size you draw your chart is depending on you.
just reduce the width and height you pass to your drawing function.

tried headless ??

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.

in a pie, 1 category => 1 value

so you'll have to change it !!

the Interval Class public class Interval { // low Limit (value unit) private double lowLimit = 0; // high Limit (value unit) private double highLimit = 0; // max value, no computed value above this private double maxValue = 0; // separator size (soemwhat pixel) private int sepSize = 10; public Inter...

I've been searching for months for that kind of bug, sometime my graph just did'nt show ... I found that it was because sometime, the value I had produced PathException, it could not be draw, hanging in a native call. track down null, 0, infinite ... etc ... especially with dynamic , oyou often comp...

sorry, but i can't figure what you mean by Timing Diagram.

could post an example ?

have a look is the margin and insets in your plot / renderer
i think you find what you need there ....

use the axis.setRange() fonction

what graph do use use exactly ?

ellispses is done by the Jcommon TextUtilities.createTextBlock() function.

so find which of your axis does the call to it and override it with a greter width ...
for CategoryAxis, the key is in the createLabel() ....

as with any opensource projet, the ultimate doc is .. the code !

It's enought for the average java developer to understand how it works.

Depending what you wanna do, you'll need just extending an existing class, but more often, you need cloning and customizing a class.

I made a first shot ...



is thats fitting what you need ???
