Area-line series charting in web Intelligence

Dear community,

I know web I 3.1 has limitations in its charting capabilities. Have you guys tried achieving a Area-line series combo chart type in web I. I know we can do bar/lines. Just wondering if there is a manual way in achieving the Area-line type. or can we embed crystal charts in web intelligence?

Data source is SAP BW and BOBJ 3.1 SP3

Thank you
