Allow various combinations of combo chart. Example: Area and line chart. Bar and area. or two lines with different axis (pct and $). Similar to functionality in Excels combo charts.
Great suggestion. I'm coming particularly unstuck on the dual axis issue. Even when I am presenting 2 series which are on the same number fomat I'm having difficulty. eg clicks and sales. Both normal numerical measures, but with such huge disparity between the volume of each measure, the graph is impossible to read. I've got 10,000 clicks, and 12 sales, so my sales line looks like a flat line running along the bottom of the chart
