Chart2 is the re-implementation of the charting component of OpenOffice.org. It is integrated in OOo 2.3.

Charts are used for visualizing data sets from e.g. spreadsheets by two and three dimensional diagrams. There are a lot of different two- and three-dimensional chart types you can choose from. This page gathers information about the new chart implementation of OpenOffice.org. It is especially written to help newcomers to the process of developing for the new OOo chart module.

If you would like to participate, if you have comments or questions related to the chart you are welcome on the graphics mailing lists: (users,dev,features,bugs,cvs)@graphics.openoffice.org. See also the side-box with some useful Links.

Development

If you like to help developing the chart, you can find useful information here.

To find a concrete task to work on, check the issue queries of open chart bugs and features. Maybe there is something that catches your interest:

Also check the easy-to-dev issue list to see whether there are currently development opportunities for newbies: Easy to develop issues

Testing

If you want to help the QA team have a look at the QA contribution page. You can help a lot with identifying new problems or verifying fixed and integrated issues!

Download the latest developer snapshot and give it a try. When you find a bug please check whether someone else already did submit an issue for that problem. The following issue list can help you with the research:

There is also a spreadsheet document containing the open chart issues. It is nice for sorting and filtering, but it is not up-to-date. Have a look at the first line to find out when the query was done.

If the problem is unknown you are welcome to submit a new issue. Thanks a lot for your help!
