In general, I don't think mpl is threadsafe at all; it uses global
variables, such as all the rc parameters, that could easily be modified
by one thread while being used by another. I think that great care
would be needed if one wanted to have multiple threads making plots.

Mattias' suggestion is a good one if you have a full TeX environment
installed.
Otherwise, it looks like you're using some features that are only
available in 0.91.x (but not earlier versions), for example "\sin". If
you can, try upgrading.

At least the Agg backend *looks* to be reasonably threadsafe -- there
are no obvious gotchas like global variables etc. Note, though, that
multithreading may not gain much in the way of performance since the
global interpreter lock is never released around long-running C blocks.
However, I can

Replacing the line above with pylab.hold(False) seems to put me in a
non-stop loop. I'll run the test code in winpdb, but still want suggestions
on how to get the output I need.

That's cool'n'all, but when is svn going to make it into a Windows

Hi All,
Is there any way in MPL to do gradient filled bars like you can in
Excel? (click data series -> format data series -> patterns -> fill

Hi All,
Why does the following render small gaps horizontally between the bars?
import pylab
data = [1,2,1,2,4,2]
labels = pylab.arange(len(data1))
pylab.bar(labels,data1,width=1,linewidth=0)
pylab.show()
How do I make the small gaps go away?

It looks like it may be Windows-specific. I can create .eps files with
math on mpl-0.91.2, Python 2.5, gs-7.07 on Linux without problems.
Someone with a Windows installation may need to look at this.

then you must have a version in which some of those scripts h

Not sure if this is relevant, but NX is a frequently used shorthand for

Does anybody see greek symbols in eps files with mpl 0.92.1?

Hello Bernhard -
When I set the fonttype to 42, the eps file gets much bigger, and the fonts
seem included. The file contains the same section as yours:

I'm trying to plot a bar chart something like:

data1 = [1,2,3]
data2 = [4,5,6]
labels = [now-timedelta(1),now,now+timedelta(1)]

However, this blows up:

Actually, I did manage to fix this by specifying a zorder of 10 for the
plots and a zorder of 1 for the grid

This is what I was after, thankyou :-)
However, the lines show up on top of the lines plotted, not behind them
as I'd expect.

Hello Lorenzo,
maybe you don't really use Tex to build the labels and mathtext does not
support any Tex-functionality.
if you use:
from matplotlib import rc
rc('text', usetex=True)
import pylab as p
it should work. Alternat

Hello Chris,
for only horizontal lines you can use 'ax.yaxis.grid' like:
---
from pylab import *
figure()
ax = axes()
ax.set_yticks([0.0,0.5,1.0], minor=False)
ax.set_yticks(list(linspace(0.0, 1.0, 11)), minor=True)
ax.yaxis.grid(which='minor')
show(

This feels like what I should be wanting except:
- why does it need explicit parameters? why can't it pick up its lines
and labels automatically, like legend does?
Dear All,
I think the solution to my problem must be a one-liner, but I have
been unsuccessful.
I am trying to use latex formulas (nothing dramatically complicated)
inside a figure.
I suppose everything is working correctly on my system.

Thanks, that worked (well, it did what it was supposed to...) so it'd be
nice if it was in the online docs as well as the docs
