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
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
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.
