[Matplotlib-users] Arranging subplots on a square regular grid

If you're okay with a fixed figure size, you can use plt.figaspect to set
this up fairly easily: (i.e. this will be incorrect as soon as you resize
the plot window)
import numpy as npimport matplotlib.pyplot as plt
nrows, ncols = 8, 12
dx, dy = 1, 2
figsize = plt.figaspect(float(dy * nrows) / float(dx * ncols))
fig, axes = plt.subplots(nrows, ncols, figsize=figsize)for ax in axes.flat:
data = np.random.random((10*dy, 10*dx))
ax.imshow(data, interpolation='none', cmap='gray')
pad = 0.05 # Padding around the edge of the figure
xpad, ypad = dx * pad, dy * pad
fig.subplots_adjust(left=xpad, right=1-xpad, top=1-ypad, bottom=ypad)
(From here, for reference:
If you need the spacing to remain constant as the figure size changes,
it's possible, but more complex. You may find it's easiest to use
draw callbacks in that case.
Hope that helps,
