Saving JFree charts

Hi David,

I've seen that the charts can be saved as .png files and this happens really great with good precision. the developer's guide has a section that talks about saving images to pdf documents. Is it possible to save the image directly into another application such as MS Word, Power Point, Excel, etc. instead of just saving them as images? Having this feature of saving the chart into a powerpoint or word(etc) file would really help where large data is being dealt with (as in my case). Would highly appreciate your help in this!

Thanks,
Juhi.

Take a look at the Jakarta POI Project - Java API To Access Microsoft Format Files

Hello,

Some more infos on this forum :

How to export data into Excel from JFree chart?

improve image quality/resolution on export

Can I copy/paste the plot to clipperboard??

How to use charts with MS word/powerpoint ?

I had made some tries to add a clipboard functionality to my swing app. As mentionned, I wanted to get a vector format to have a nice display/printing. I droped the idea of SVG as it gets too difficult for an end user to manage how to add an SVG image in their word document. As for now, I also dropped wmf, as the only library I had found was not working so well - 90-95% OK but some issuses remained ; this is was partially a problem of WMFWtriter (fonts display not well renderered - Piet Jonas did some work to enhance this), but mainly a problem of WMF primitives that are not so complete as Java2D...

I had no time going further, that's why I did implement a bitmap copy/paste with high resolution PNG encoding (have a look at the mentionned links).

If I'll have more time, I'll have a try with an other java vector graphics library : FreeHEP Java Library.

Hope this can help you a little,
Regards,
Arnaud
