Tested here on firefox 3.6 (Ubuntu) and I cannot reproduce what you described. Looking at the files, the only difference is that one png has an alpha channel while the other one doesn't. The one that caused you problems is the one that has the alpha channel. You should probably check external dependencies like libpng (1.2.37-1 here). -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkuNGzAACgkQYh11EUYTX9SarQCdHuUkqBzcLJq7A8R37QCrh0p4 Vl8AmQGE/ye1ylMueVUq5pWxEj924udU =QYcO -END PGP SIGNATURE- -- Download Intel® Parallel Studio Eval Try the new software tools for yourself.

[Matplotlib-users] How to calculate relative positions between objects
Hi everyone
I've been going around matplotlib objects trying to find a way to
pre-calculate positions depending on input.
I'm trying to create a function that draws two barplots facing opposite
directions.
This is what I managed so far:
###
import numpy as np
import matplotlib.pyplot as plt
from scipy.stats import gamma
from mpl_toolkits.axes_grid import make_axes_locatable
fig = plt.figure(1, (10, 10))
ax1 = fig.add_subplot(1, 1, 1)
ax1.set_xlim(1,0)
labels = ('0-9', '10-19', '20-29', '30-39', '40-49',
'50-59', '60-69', '70-79', '80-89', '90-99')
pad = np.max([len(i) for i in labels]) * .15
divider = make_axes_locatable(ax1)
ax2 = divider.new_horizontal(size="100%", pad=pad, sharey=ax1)
fig.add_axes(ax2)
N = 10
ind = np.arange(N) # the x locations for the groups
width = 0.35 # the width of the bars
x = [gamma.pdf(i, 1, scale=2) for i in range(N)]
y = [gamma.pdf(i, 5, scale=1) for i in range(N)]
ind = np.arange(N)
ax1.barh(ind, x)
ax2.barh(ind, y)
for loc, spine in ax1.spines.iteritems():
if loc in ['left','top']:
spine.set_color('none') # don't draw spine
for loc, spine in ax2.spines.iteritems():
if loc in ['right','top']:
spine.set_color('none') # don't draw spine
ax1.set_title('Men')
ax2.set_title('Women')
ax1.set_ylim(0, N)
ax2.set_ylim(0, N)
# Name bars
ax1.set_yticks(ind + width)
ax1.xaxis.set_ticks_position('bottom')
ax2.xaxis.set_ticks_position('bottom')
ax1.yaxis.set_ticks_position('right')
ax2.yaxis.set_ticks_position('left')
for tl in ax1.get_yticklabels():
tl.set_visible(False)
ax2.set_yticklabels(labels,
horizontalalignment='center'
)
for i in ax2.get_yticklabels():
i.set_position((-(pad * .12) , 0))
plt.show()
###
However I would like to generalize this function but he space between
the two plots and the position of the labels is giving me a hard time.
In particular, the lines:
pad = np.max([len(i) for i in labels]) * .15
i.set_position((-(pad * .12) , 0))
include two values (.15 and .12) that are completely arbitrary and
defined by trial and error for current labels.
However with different labels:
labels = ('-9000', '10-19', '20-29', '30-39', '40-49',
'50-59', '60-69', '70-79', '80-89', '9-99000')
the values are no longer valid and the final image is no longer properly
aligned.
I know my current approach is not the proper way but due to the
complexity of matplotlib, my very superficial knowledge about it and the
overwhelming documentation this was the closest I could get.
In the end I would like to contribute the final result as something to
be included in the gallery/examples section of the website as I'm
positive that it will be helpful to others.
Any comment or suggestion is extremely welcome.
Cheers,
Renato

Re: [Matplotlib-users] bar/hist plots, bottom on top or right axis

But it seems the approach I was trying is not as flexible as I thought it would be. Right now I'm trying mpl_toolkits.axes_grid.axes_divider but I still have a problem on locating the yaxis labels in a centered format. Anyway this is a bit out of the scope of the initial thread.

[Matplotlib-users] bar/hist plots, bottom on top or right axis
What I'm trying to accomplish is something like: http://bm2.genes.nig.ac.jp/RGM2/R_current/library/plotrix/man/images/big_pyramid.plot_001.png For that I was trying to use subplots where both draw in horizontal orientation but one will be flipped or mirrored. I couldn't find any parameter to do so. There is left for horizontal plots but no right. The same goes for bottom, but no top. Is there any way to achieve this?

[Matplotlib-users] Names in boxplot x axis
Hi everyone, I've been using matplotlib for a while but mostly using the pyplot functions and going as far as changing their initial input parameters. Now I need to make a boxplot and include names on the X axis as opposed to the default numbers. I've searched extensively on the docs and using google but I reached a dead end. So, could someone point me in the direction of how can I change the plot to use names instead of numbers on the x axis (vertical boxplot) or y axis (horizontal boxplot)?
