The chart reimplementation is still ongoing. Be aware that this version is a Beta and still contains a lot of bugs, missing features and maybe incompatibilites. So don't use it for important work. If you create documents with this version do not distribute or keep them as they might not be correctly loaded in official builds. As this is a developer snapshot build it should not conflict with your normal OpenOffice.org version on your computer.
A respin of the beta is now available at the chart website where this bug is fixed.
