How to show a secondary vertical axis to the right of a chart when using charts module? I have created a chart of two variables, using Charts module. To do so, I used the Views integration of the charts module, and selected 'Chart' as the views style.

The result I got so far is that the chart is shown using the same vertical axis (y-axis) on the left (one for each variable).

Question: Is it possible to use two vertical axes, so that the primary axis is shown on the left of the chart, and the secondary on the right?

It is now incorporated in the (brand new) Charts community documentation, within Use sub-charts to create dual-Y-axis charts, which details the 4 steps to create such charts.
