Chart2 is the re-implementation of the charting component of OpenOffice.org. It is integrated in OOo 2.3.
Charts are used to illustrate data sets e.g. from spreadsheets to get a better understanding of the data. A lot of different two and three dimensional chart types are available to 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.

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 Gevelopers Guide
- FAQ about Chart API Compatibility
- Published UNO API (com::sun::star::chart)
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)
- Chart Issues in other components. Component is not Chart, but the summary contains the words diagram or chart.

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.
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!
