The Chart module was exchanged completely on the way to OpenOffice.org 2.3 (starting with SRC680_m213).
This is the basis for further enhancements and long awaited features.
This page documents ongoing work, implemented and still missing features. It also links to further useful information around the chart.

Helping with the Chart
Development
If you are new to OpenOffice.org development have a look at the more general pages first:
- Getting started with OOo development
- Participate in OpenOffice.org Programming
- C++ Coding Standards.
The file format used for OpenOffice.org is the ODF format.
- Currently, ODF 1.1 is in use.
- The upcoming format ODF 1.2 is still in progress (see open action items).
If you like to help developing the chart, you can find useful information at the following places:
- Chart chapter in the Developers Guide
- Chart chapter in the BASIC Developers Guide
- FAQ about Chart API Compatibility
- Published UNO API (com::sun::star::chart)
- Rough overview of the code Structure in module chart2
- Notes on some technical issues
The CVS module for the chart implementation is chart2. It is a submodule of the graphics project. The chart implementation makes heavy use of UNO (Universal Network Objects), thus it would be good to learn about UNO first. The new chart does support a published stable UNO API com::sun::star::chart for external use. There is also an internal API com::sun::star::chart2. The internal API is not published and is not guaranteed to be stable. It is subject to further changes - so don't count on it in scripts or something! Furthermore several things you can set with the internal API will not be saved by the application. So for stable work please use the published standard chart API com::sun::star::chart.
If you have questions or comments related to the chart you have several choices:
- Use the forum OOo Community Forum on Calc
- Use the mailing list dev@graphics.openoffice.org
- Use the chat #chart2.openoffice.org on freenode
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:
- Open chart bugs (defects and tasks)
- Requested chart features (enhancements and features)

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:
- Open chart bugs.
- Fixed issues that have not been verified or closed yet
- Verified issues that have not been closed yet (checked in the master)
- Or create your own query.
If the problem is unknown you are welcome to submit a new issue. Thanks a lot for your help!
