Question: multi axis line chart

[timofurrer]

Just a quick question: is it possible to display two Y-axis in a line chart? I basically have a chart use case where I have the time axis in X flowing from left to right and two data sets on different scales. I want to have one scale on the left Y axis and one on the right Y axis. Is that possible?

If not, that issue becomes a feature request, I suppose :)

Anyways, great package!
