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

Example Chart made with OpenOffice.org 2.3 (ods-file see File:ProgrammingLanguages.ods)

Development

If you are new to OpenOffice.org development have a look at the more general pages first:

The file format used for OpenOffice.org is the ODF format.

If you like to help developing the chart, you can find useful information at the following places:

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 stable UNO API com::sun::star::chart and a new unstable UNO API com::sun::star::chart2 which is still under construction. Be aware that the chart2 API is not published and is subject to further changes in future - so don't count on it in scripts or something! 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:

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!
