# ListPlot - plotting values with different range

I have three tables: L, S and U. In first table I have values from range (0,1), in second from (0,2*10^27) and in the third one from (0,50). No I want to plot all this three tables (tables have the same domain) together. But because of a very different range, I see for example only values for U, and rest are just like a small points very near to axes x. I was trying to use ImageCompose, because I have mathematica 7, so I can't use Overlay, but this functions are only for two plots. Is any other solution how can I plot this three functions together and make the plot more legible?

How about plotting {L, S/(2 10^27), U/50} ? – A.G. Dec 28 '13 at 22:35

It is all about rescaling, - visual with Overlay or @A.G. idea in the comment. So:
L = Abs[Rescale[Accumulate[RandomInteger[{-1, 1}, 1000]]]];
