Is it possible to generate a chart that has different Y axes (and units) on the left and right side? Here's an example image of the kind of thing I'm trying to chart (it shows engine performance):

Note how the horsepower and torque are plotted against the engine RPM (rotations per minute). The horsepower (in units of hp) is on the left Y axis and torque (in units of pound-feet) is on the right Y axis. (Sorry I don't have a chart in metric

Thanks a bunch for any information!
