Issue 77362

Bjoern advised me to write this issue. He knows about this file.

I have add 2x250 rectangles to the chart. Position,size and transparency of them
are manipulated by macros. After changing something with the rectangles the
diagram does not update automatically but you have to press F9.

I'll attach two files. Please test first "oberuntersumme_Chart2_workaround" to
see how it should work. In that version I added oChartDocument.setModified(true)
as Bjoern told me. Change something in the cells B8, B9, or B10 and then press
"Rechtecke neu zeichnen". The diagram shows the modified situation. You can also
use "zeigen" and "verstecken" to change the diagram.

Now do the same in "oberuntersumme_Chart2". The diagram doesn't actualize
automatically.
