subplots with linked axes

Community matplotlib-users
1

I would like to plot two or three graphs as subplots in a figure and control the axes such that when one graph is zoomed the others are adjusted too. I was hoping there would be a notification mechanism which would allow me to catch a rescaling of one subplot and redraw the others in step. Can anyone suggest a method of doing this?

ax1 = fig.add_subplot(211)
ax1.plot(something)

ax2 = fig.add_subplot(212, sharex=ax1) # ditto for sharey
ax2.plot(something_else)

It sounds like what you want is to use the "shared axis" functionality.

See the shared_axis_demo.py

Cheers,

Thanks Michael!

I'm new to this but I'm still kicking myself for not spotting it. Just
what I was looking for.
