Adding subcharts / creating combo charts using python-pptx

[arpit0515]

I have been desperately trying to create combo charts using python pptx & have used the below references for doing the same. I keep getting the error AttributeError: 'CategoryWorkbookWriter' object has no attribute 'x_values_ref'. Is there any other way of creating combo charts using python-pptx?

1. Python-pptx (Scanny #338)
2. jbq Python-pptx commit
