Ok. Chart export code is shared between all applications.

You'll find the source code in xmloff/source/chart. What we need to do
to follow ODF is adding the relevant entries to
http://opengrok.libreoffice.org/xref/core/xmloff/source/chart/PropertyMap.hxx
and write the export code similar to the y error bar export code.

I hope this helps you a bit more.

Thorsten, is there a preferable namespace for our custom
elements/properties? Something like libo:?

I saw it and the code looks really great. I will test build it and
have a quick look through the code and have a quick test but IMHO it
is ready to hit master even without the ODF import/export.

It would be great if you could add some test documents for your new
feature to http://cgit.freedesktop.org/libreoffice/contrib/test-files/
that will allow us to check that we did not introduce regressions in
the future and as soon as I finally get the chart test working add
them to in-build tests.

Thanks a lot for this great work. Do you have already have an idea
what you want to hack next? Chart2 needs a lot of love and if you want
we can find some more tasks there.

Markus
