same figure window, different scales
Posted:
Mar 22, 2013 1:25 AM


I have a code where I need to show 3 plots on the same figure, but one is so small, that it looks like a line running along the bottom.
Is there a way to have 2 scales in one window so that I can plot my 2 similar plots on a scale , and my smaller plot with a second scale?
Code below if you want to see for yourself, the blue one needs to be scaled in the first window.
thanks all, Alex
