The target document is not relevant here, I need information from the 
source document. But the tip to look at FilterBase helps indeed. 
FilterBase has a getModelFactory() and a getModel().

Solving the problem in DrawingML instead of ChartExport would be better, 
because ordinary shapes have the problem too, that the transparency 
gradient is not exported in case of solid color fill.

Kind regards
