Is JFreeChart using AWT/Swing internally ?

[inder.chaurasiya]

Hi Guys,

Request you to reply asap about JFree Chart is purely written on java or internally it is using AWT/Swing.

Because JFreeChart is saying that it is written 100% on java but design looks like using AWT/Swing.

Thanks,
Inder

There is no point in saying "Request you to reply asap". See the post on How to Ask a Question about JFreeChart - http://www.jfree.org/phpBB2/viewtopic.php?f=3&t=24715.

I'm not sure if JFreeChart uses Swing, but it definitely takes advantage of AWT. However, I'm not sure what gave you the impression that would make it not pure Java, since AWT has been part of the core Java libraries since Java 1.0 and Swing since 1.2.

JFreeChart uses the Java2D API extensively, and Java2D can be considered to be part of AWT.

There's the ChartPanel class to provide good integration with Swing, but otherwise JFreeChart is independent of Swing.

As the previous poster said, using AWT, Java2D or Swing does not stop code being 100% Java. These APIs are part of J2SE.
