Multiple y-axis

[healem]

Hi.
I'm trying to plot data with multiple y-axis. I've figured out how to get the secondary y-axis to appear, but I can't figure out how to associate data with it. Also, how can I chart column and spline on the same chart? Basically, I'd like to achieve something like this: http://www.highcharts.com/demo/combo-multi-axes

Thanks!
