Chris,
It should produce a "test.png"; it is using a non-interactive backend. 
It works on my machine.

Hey All,
Is there any way I can control the location that a tk figure window is 
shown on screen?
I can control the size fine with:
pylab.figure(figsize=(10,10))
...but this produces a figure that, while it's the right size, is 
rendered with the top left of the window in the middle of the screen.
If I can get it to be to-left, then it will all be visisble without me 
having to move it with a mouse ;-).
Any ideas?
Chris

I tried this example, and it generates no output.
Is that to be expected?

That worked, thanks.

Hello,
I wrote a Python application using GTK+ and Matplotlib. I normally use
the application in full screen mode (1680x1050). There is a big gray
border. You can reproduce it using the embedding_in_gtk.py from the
examples and full screen it.
How can I remove this grey border? The numbers on the axes should not be
cropped.
Regards,
Benjamin Drung

Unfortunately, matplotlib doesn't automatically provide anything like 
the rich text formatting you describe. The best you could do is to 
manually position the text.
Cheers,
Mike

Hello Joseph,
I'm not sure I understand correctly, but it seems to me that the number of 
plotted lines (from errorbar, len(gca().lines) ) is large compared to your 3 
labels. That's why only the lines of the first errorbar are used to build the 
legend.
It might to helpful to use the 'label' kwarg of errorbar to properly connect 
the errorbar to a label. After that you can build the legend with 'legend()'.
regards Matthias
PS: Could you provide a complete example, if my suggestion doesn't help, 
please?

Hi,
I'm a matplotlib N00b and I have
============
from pylab import *
multimap =
...
figure(1)
for index, key in enumerate( multimap.keys() ):
		
	p = subplot(6, 5, index+1)
	xlabel('intraclashes kcal')
	ylabel('count')
	p.axis([0,70,0,0.2])
	vals = multimap[key]
	#p.set_autoscale_on(False)
	p.hist(vals , 20, normed=True, facecolor="red")
show()
===========
And depending on if I comment or uncomment the
#p.set_autoscale_on(False)
I get either variable axes ranges
http://people.binf.ku.dk/biehl/penelope/mpl_var_axes.png
or squished histogram bars
http://people.binf.ku.dk/biehl/penelope/mpl_fixed_axes.png
Is there a way to fix this?
Thanks,
Anders

Hi:
I'm having a problem where the lines I plot show up in one style (all
solid, with different colors) while the legend shows them to be a
different style (all blue, different dashes). I used the following
code to plot:
labels = []
dir_names = {'U' : 'UP', 'D' : 'DOWN', 'L' : 'LEFT', 'R' : 'RIGHT'}
for dir in lines:
	xa = sorted(lines[dir].keys())
	ya = [lines[dir][x][0] for x in xa]
	yerr = []
	for x in xa:
		if lines[dir][x][1] > lines[dir][x][2]:
			# no bound data
			yerr.append([0,0])
		else:
			yerr.append([lines[dir][x][1] - lines[dir][x][0], lines[dir][x][2]
- lines[dir][x][0]])
	yerra = array(yerr).transpose()
	errorbar(xa, ya, yerr=yerra)
	labels.append(dir_names[dir])
legend(labels)
show()
Here's the result:

What am I doing wrong?
Thanks for the help.
Joseph

Hi,
I would like to add a Text that has three colors, "bbbbbbb, gggggggg,
rrrrrrrr" where bbbb is in blue, gggg is in green and rrrr in red.
I am able to create three texts but how can I have them position 'side by
side'?
Thanks,
Olivier

Perfect, this works like a charm. And if so desired, this could also
be done without changing the symlink by just changing the Python
Makefile to use gcc-4.2 and g++-4.2. Thanks!
