Multiple Y Axes...

Hello NG,

    please excuse my poor knowledge of matplotlib. I am searching for a way
to do plots with multiple Y axes: for those of you that use Matlab, I am
looking for something like plotyy and, if it's possible, also something more
complicated like plotyyy or ploty4 (available at Matlab Central File
Exchange) that allow you to put a third and fourth Y-axis on a plot, like in
this screenshot:

Is something like this possible with matplotlib? Is there anyone that has a
small example on how to do it?

Thank you in advance for every suggestion.

Andrea.

Hello Andrea,

Have you looked at the file, two_scales.py, in the examples
directory? This example would appear to show you how to create
plots with two or more scales per axis.

I've run the two-scale demo, but there is a big problem when I zoom into it (in the gtk gui): Only one of the 2 scales (the left one) changes.
Is there a way to select/zoom/move the second scale?
I changed the date_demo.py to display 2 stock quotes, but it is actualy unusable because of this.
Any help welcome
