Hi Walid, I'm new to mpl, too, but I just installed it on OSX and
first had that problem, too. I solved it because I did not have libpng/
libjpeg installed, for which a pkg installer for OSX is available here:

Hope this solves your problem, t
My lables for the different bars are not centered below the bar but are
all to the left side of the bars (lower left corner).
This is what I am basically doing:
axes = panel.figure.add_subplot(2, 2, 3)
...
axes.bar(indx, values, color=colors)
axes.set_xticklabels(lab
the patch3dcollection object not good for legend figure, I am having trouble
thinking of a work
around. Is there manually a way to insert artist and labels into the legend
and make it such that it is independent from the axes? Using a proxy artist
requires it not be part of the axes correct?

Put my glasses on and found the rotation property in the documentation,
only issue left is centering the labels below the bars.

OK, I mostly understand John's example and have
adapted it in the attached Histogram class, for
whoever might care. (The file is a working
example.) Thanks!
Here are my remaining questions.
1. To get a new histogram, I just change the
data in the vertices object and then ask my

Ooops, forgot the attachment.

I have asked this question before. How do I set the linewidth of the
axis frame? Long ago, I used gca().get_frame().set_linewidth(2). More
recently, I used gca().frame.set_linewidth(2), but this doesn't seem to
work anymore. I've tried gca().patch, to no avail. Any suggestions?
Thanks.

Blitting will improve the performance when significant portion of your

I guess you're using 0.99?
Use spines instead.
for example,
gca().spines["bottom"].set_linewidth(2) # it only changes the
linewidth of the bottom spine.
also, see this example,

Hello,
I have a list of X,Y coordinates and a ratio associated with each
coordinate. The X and Y coordinates are continuous but random from 50-500, I
would like to make a continuous heatmap of the ratios at each coordinate.
One caveat is that the coordinates are clustered together do some bixes

Can anyone explain how I could:
-Open two shapefiles
-Open a raster
-Plot a histogram of the values within each shapefile on the same plot and
display the mean and Standard Deviation of each plot.
Thanks

You need to adjust the positions of the ticks.
bar command (by default) creates boxes so that their left side
corresponds the first argument.

so, in your case, something like below will work (0.4 from 0.8/2 where
0.8 is t

Are you using the align='center' kwarg to b
sct1 = axes.scatter(x,y, c=some_list, cmap=plt.get_cmap(colmap))
colors = sct1.get_facecolors()
The return value is an array of rgb values.
