I'm running the following on mpl 1.2.1:
import matplotlib.pyplot as plt
import numpy as np
A = np.arange(1020*1368*3, dtype=np.uint8).reshape(1020, 1368, 3)
plt.imsave('dimcheck.png', A)
The OS tells me the picture has 1019x1368px. So one row is missing. It
works fine for e.g.
You could, before plotting, sum the different image arrays? Depending on
whether you are plotting RGB(A) images or greyscale images, you could take
the sum of the color channels, or take a weighted average.
The method you use here depends strongly on the image type, but it will
reduce memory
Those numbers actually make a lot of sense.
For a 4k by 4k 2D array of 64-bit floats, you're using 128MiB of memory,
just to store them. Displaying such an array with mpl would take a copy of
that and add some objects for housekeeping (on my machine about 150MB to
display one such array together
Hi Daniele,
not sure, but it seems to work for me. Did you do a plt.draw() or
plt.show() to reflect the changes?
Kind regards,

The matplotlib function contourf() should do what you want. Have a look at
this example:

I apologize if it is not what you're looking for. I haven't read your whole
script, because it is not *a minimal working example*
If I understand your intent well, then you want to make slices through a 3D
volume and show such slice planes.
I’ve always done this with the various functions of an Axes3D instance that
allow you to specify the slice position. On the matplotlib examples page,
there is a good example that showed
I apologize if this has been fixed already, I can only check different

Adding a caption to a plot inserted with the `plot` directive from mpl's

The solution below is maybe not optimal, but it's something you can figure

Hi Charlie,
I am sorry about this. I confused the installations on my workstation at

I am trying the numpy-scipy-matplotlib stack on Opensuse 10.2 from

What is your matplotlib.__version__ ? I think that code only made it's
way into v1.2.0 (the latest stable), and was did not make it into
v1.1.1 (or anything before it)
I'm running 1.1.0 - I'll upgrade it now. Thanks for the help!

fudge
it by drawing a bunch of Collections (usually a PolyCollection or
LineCollection, http://matplotlib.org/api/collections_api.html) on a normal
cartesian axis, and then hide the axes, ticks and ticklabels.
This approach works for me, though your mileage may vary.

You must set the desired backend from the very begining and before
importing pylab o pyplot.
That did it - I made the change in my .matplotlibrc file and it no longer
