Create charts using Java code
Please let me know if there are any APIs that allow creation of charts (bar graphs / histograms / pie charts, etc) through Java code. At this point of time, I am not particular about the output format - Excel file / Matlab file / R (Stats language) etc. But, it would be great if something exists for Excel.
The important thing is that I must be able to create a chart through Java code only, and there must not be a requirement for predefined external templates as is the case with jxls.
Thanks!

With jxls, we need to create a template.
POI doesnt seem to support charts.

http://poi.apache.org/ - this is not so for graphs but for read/write MS docs, xls
ASKER
Right. Do we have something for graphs in Excel?
If possible, please post the link to the manual for JFreeChart.

JXLS is for graphs in Excel created by Java
ASKER
Right. But, the problem with jxls is that it requires a template file. I want to do everything from Java without having to create templates first.
Type JXLS in the serach here on EE and maybe limit to the latest days - you'll see soem traikls
This is the manual
jfreechart-1.0.13-A4.pdf

But you can wriote templet in Java with POI first (tjhough it seesm too much work to me - better do them once and use them)
ASKER
That's a nice idea!
Well, I'm glad you like it - id you need to create them all the time different on the fly, then maybe it is a way

Java
Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
