Home for SWT JFreeChart?

Hi all,
I'm updating a Swing application (www.debrief.info) to Eclipse. The application makes a lot of usage of interactive Time-Variable plots via JFreeChart.

I'm aware of the SWT_AWT wrapper available but I don't expect it to support the interactive (zoom/pan) features of JFreeChart as well as I'd like. I'm considering approaching somebody with more free time than me to rewrite the component in SWT (via Rentacoder or similar).

Has anybody already attempted this conversion? If not, can anybody provide me with a broad estimate of programmer time required to perform the conversion (I've got my own idea, I'd be interested in other opinions).

Lastly, would JFree be interested in taking ownership of the completed library?

Cheers,
Ian.

I want to do it. but, It's too difficult to convert it to me.

There is RChart for SWT.

Thanks for that, "silent".

At first your recommendation didn't seem an option - since the target application is an open-source app for which no licensing costs are required.

On reflection though, the "unlimited distribution" cost is less than I'd expect SWT-JFreeChart to cost, and it may be an option.

I'll save RChart as a "fallback" option.

Cheers,
Ian.

There is another option you can try, I'm currently investigating this. It is open source. http://www.eclipse.org/birt

I don't know enough about SWT to give an opinion on how much effort this would be.

Yes. If there is someone who wants fame and fortune (well, fame anyway) and is willing to maintain the library in parallel with JFreeChart on Java2D then that would be ideal. I'd love to do it myself, but I'm already spread too thin.

I read somewhere that SWT is using Cairo for its vector graphics library - can anyone comment on that? I'd like to know more about that, for sure.
