[Libreoffice] Need help with symbols in object dialog of chart data series

[Regina Henschel]

Addition:
I found, that painting of the preview is done in class SvxXLinePreview 
in svx/source/dialog/dlgctrl.cxx. It uses the symbol graphic without any 
transformation and therefore is not the reason of the bad preview. I'm 
currently exploring tpline.cxx. Still any hints are welcomed, how to get 
a proper display of the symbols in the dialog.

Kind regards
Regina
