[Matplotlib-users] Problem setting clim for subplots

[Julien C. <jul...@gm...>]

Dear all

I am puzzled: in the following code, when I call clim() *after* having
created 3 subplots, only the last subplot takes the new limits into
account. All other subplots ignore it. Xlim(), on the countrary, works as
intended. Everything works fine when I set the clim()  at creation time.

Am I doing something wrong, or is this a bug, please ? Any help much
appreciated !
The offending code is below.  I use python 2.7.5
andmatplotlib-1.3.x-py2.7-macosx-10.8-intel.egg

Thanks for any help!

import matplotlib.pyplot as plt
import numpy as np

x = np.asarray([[1, 100, 20], [50, 1, 20], [20, 10, 5]])

# Problem when setting clim *after* having created the two subplots:
# only the last subplot honors the request

# 1. Create the pcolormeshes in subplots
h = plt.figure()
for i in range(131, 134):
    plt.subplot(i)
    plt.pcolormesh(x)
    plt.colorbar()
print(h.number)

# 2. Now set the clim()
plt.figure(h.number)
for i in range(131, 134):
    plt.subplot(i)
    plt.clim((5,10))
    plt.xlim((2,3))

plt.savefig('after_creation.png')
plt.show()

# No problem when setting clim *while* creating each subplot
h = plt.figure()
for i in range(131, 134):
    plt.subplot(i)
    plt.pcolormesh(x)
    plt.colorbar()
    plt.clim((5,10))
    plt.xlim((2,3))

plt.savefig('while_creating.png')
plt.show()
