In general, here's the memory usage to be expected from imshow (if it's a floating-point, not-rgb(a) array as you have here): The original data: 4-bytes-per-pixel for float32 or 8-bytes-per-pixel for float64 (in your example the array is float64). Intermediate float data: *if* the original is not float64, then an intermediate float64 is created (not the case here) The colorized data: 4-bytes-per-pixel at original array size The sized data: 4-bytes-per-pixel at the scaled figure size I hope I'm not forgetting anything, but the point is that to support high-speed rendering of plots, the memory usage is much greater than the data itself.

Re: [Matplotlib-users] matplotlib font in cairo
We went through this a few years ago on the Cairo mailing list. The short answer is you need to copy the fonts from mpl-data to C:\Windows\Fonts to correctly use Cairo. The long answer: Cairo uses fontconfig for font lookup, which by default searches the system font directory (C:\Windows\Fonts). There is an fontconfig API to add another font directory to search, but it is not exposed to Python. The cairo guys don't want to expose it in pycairo because that API is not technically part of cairo, but there isn't a proper Python wrapper to fontconfig, so until one is created we're sort of left with our hands tied. This is probably worthy of a FAQ in the docs. Mike copyrig...@gmx.de wrote: Hallo, I'm try to use MathTextParser output for cairo in my wxpython gui.

Re: [Matplotlib-users] align title of subplot with ylabel
On Mon, May 17, 2010 at 10:08 AM, hettling hettl...@few.vu.nl wrote:
Dear all,
I'm struggling with the following problem plotting my data:
I have a figure with two panels next to each other, which I want to
label 'A' and 'B'. I want to left-justify my panel labels, but not to
the box that contains the plot, but to the y-axis label. I played around
with 'text()' and 'title()', but did not find a good solution except for
giving the coordinates manually to 'text()'. This would be very
inconvenient though, because I have many different plots on different
scales.
Here is what I tried:
###Code
import scipy
import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.add_subplot(121)
plt.plot(scipy.sin(scipy.arange(1,100, 0.001)))
plt.xlabel('xlabel')
plt.ylabel(ylabel)
plt.text(0,1,A, fontsize=14, transform=ax.transAxes)
ax = fig.add_subplot(122)
plt.plot(scipy.cos(scipy.arange(1,100, 0.001)))
plt.text(0,1,B, fontsize=14, transform=ax.transAxes)
plt.xlabel('xlabel')
###End Code
So the texts 'A' and 'B' should be a little bit higher and more to the
left. The 'A' I want to align with the y-axis label of the left plot,
the 'B' with the values of the y-axis of the right plot.
I haven't thought through the solution completely, but my intuition
says that this might be helpful:
http://matplotlib.sourceforge.net/examples/pylab_examples/anchored_artists.html
http://matplotlib.sourceforge.net/mpl_toolkits/axes_grid/users/overview.html#anchoredartists
These examples show ways of anchoring artists (like Text) to certain
locations. It's probably your best bet for getting what you want.

Re: [Matplotlib-users] align title of subplot with ylabel
This can be done relatively easily with the current svn version of
matplotlib (r8319).
Below is the modified version of your code.
See
http://matplotlib.sourceforge.net/trunk-docs/users/annotations_guide.html#using-complex-coordinate-with-annotation
for how the annotation works.
While this is certainly possible with the released version, but it
will require you to write a few tens of lines of code. Basically, you
need create a custom Text class that update its position during the
drawing time.
