I need to display a chart that shows months on the X axis, revenue in $$ on the primary Y Axis, and a percentage on a secondary Y axis. This is not hard to do in Excel, but I don't see a way to do it with the native chart web part. I can define
a primary Y axis using Column series type, and a secondary Y axis using Line series type, but the chart does not display the secondary axis. Do I need to use a different tool to display the chart?
