Hi Eike,

thank you for looking at it.

I have made some tests. I seems the "normal" charts are currently always 
written with the needed chart:value-cell-range-address attribute of 
<chart:series> element.

One problem are charts in reports. The report builder has severe 
problems with charts that make testing impossible.

Another problem are pivot charts. But their use of 
table:cell-range-address is faulty anyway. So a rework can use a 
solution without it.

I have put all these into
https://bugs.documentfoundation.org/show_bug.cgi?id=131862

Kind regards
