Unequal size gangplots

Community matplotlib-users

I have followed this excellent example:
http://matplotlib.sourceforge.net/examples/pylab_examples/ganged_plots.html

but I would like my plots to be 2/3 and 1/3 of the total height of the
figure (I only have 2 plots). What do I have to do to specify the
relative sizes of the figures?

Thanks,
Jeremy

may something like

ax1 = fig.add_subplot(311)
ax2 = fig.add_subplot(212)

work?

if I look at pyplot.setp(ax1) I see a lot of things (like "position" or
"anchor" or "axes_locator") which might work.

Good luck,

Malte

I have used add_axes() to do this in the past. E.g.,

import matplotlib.pyplot as plt

fig = plt.figure()
leftmarg = 0.125 # change these numbers to taste
botmmarg = 0.125
width = 0.825
height = 0.825
frac = 2./3.
ax0 = fig.add_axes([leftmarg, botmmarg, width, frac*height])
ax1 = fig.add_axes([leftmarg, botmmarg+frac*height, width, (1-frac)*height])
ax1.xaxis.set_ticklabels()
plt.show()

Sorry it is in object-oriented style instead of pylab style...

Thanks! This looks like it might work. I'll give it a try.

You should be able to use
http://leejjoon.github.com/mpl_toolkits-gridspec/
for unequal-size plots of the type you describe.
