Multiple side-by-side axis support

[ejosowitz]

Wondering if this would be possible- I need to create a side-by-side bar chart and line graph controllable by the same alternate dimension.

In this screenshot you see an example of what I mean. I'd like to be able to define 2 bottom axes, side-by-side, and tie the bars to one and the lines to another. Then I'd like to be able to switch the dimension, from color as shown here to shape for example, and have both the bar and line charts change to show the same data broken down by the selected alternate dimension.

This doesn't seem to be possible in the current PicassoChart but perhaps a future addition?
