Hi Shawn,
Yes, it is possible to achieve this with Nevron Chart for SharePoint. You can achieve combination of Bar and Line series with the Combo Charting Type and we are providing an example which comes with the evaluation version (Charting Types >> Combo).
Combo Charts are available in 2D and 3D. Series types are specified per values data groupings. There are many per series type options. You can combine the following series types: Bar, Area, Smooth Area, Line, Smooth Line, Step Line, Point, Bubble, High Low, Stock, Error Bar, Box and Whiskers, Vector and Range.
Questions or comments, please feel free.
Best Regards,
Nevron Support Team
