Line Chart Report with 2 Different Scales?

I have a line chart with two lines in it. Sometimes the values between them differ by a hundred or more. That leaves the bottom line looking very flat. I want both of these to remain 开发者_开发百科on the same graph but is there a way to have a different scale for each line?

I was told that it is possible to have one (scale) on the left and one on the right, but I have googled and googled and have not found anything useful.

So any help would be great, thanks!
