Dual Y Axes in Charts

[Munich]

In Excel 2007, how do I create a chart (lets say a line chart) that has two Y axes? I have been looking for about 15 minutes now, but can not find any chart options that would allow me to turn this one. I have also searched this forum, but did not get any matches.

Thanks in advance.

You'll need to have two data series plotted. Right click on one of the lines and choose "Format Data Series" and select "Secondary Axis"
