Hello,
I have the following problem. I want the axes (only the y-axis, to be exact)
of a imshow() graph to be nonlinear. By default, the axis goes linearily
from 0 to (number of pixels). With the [extent] keyword, I can change that
to going linearly from (arbitrary start) to (arbitrary end).
Hi all,
I am just started to use matplotlib and have a question about
using blit method to animate plots. I wrote something like this to
show the initial plot (other part of the code not shown):
l1, = p1.plot(lineout, animated=True)
p1.set_xlabel(xlabel)
Hi,
I want to make a plot with ordinary subplots, each of which has a
second axes set created with twinx(). Now, the second axes are
always drawn over the first, but I want the main data, which is
associated with the left Y axis, to be in front. (If I understand
the code correctly, the zorder

hi,
is there a way to put a label every two o three ticks,
instead of putting it on every tick?
the following works but it's a little cumbersome:
ax.set_yticklabels([pos % 2 != 0 and '%.2f' % num or ''
for pos, num in enumerate(ax.get_yticks())])

Thank you for responding so quickly !!
I don't think these problems are related. One is a cache of math
expression images, the other is a cache of fonts.

This script does'nt work (it causes a PyAssertion error : invalid

If it's a PyAssertion error, it should have a traceback. Is there not
one?
No, this problem is not related with Matplotlib : the PyAssertion error
occurs when creating the wx.Menu ...

Maybe a little shorter is the where() keyword, and even that can be omitted:
ax.plot(t[where(s=0)],s[where(s=0)],g)
ax.plot(t[where(s0)],s[where(s0)],r)
or, shorter:
ax.plot(t[s=0],s[s=0],g)
ax.plot(t[s0],s[s0],r)

This error occurs for me with Matplotlib 0.99.1, Python 2.5.4 and 2.6.2, while
using the Qt4Agg backend on Windows XP.
Basically, savefig('aweomse_plot.pdf') barfs if I have some math text in there.

Could you try this in plain Python? I'm asking because you seem to be
getting an IPython warning about a possibly corrupted traceback:
ERROR: An unexpected error occurred while tokenizing input
The following
ax.plot(t[s=0],s[s=0],g)
ax.plot(t[s0],s[s0],r)
Whaou! That's what I call a nice pythonic syntax.

I don't think it does what you want, though, unless you are plotting
markers, not lines. With lines, you will have line segments
approximately on the x-axis across the gaps. Using masked arrays avoids
that. The gaps

Hi,
I solved it by installing matplotlib 0.99. But, on Mac 10.5 when I
used easy_install matplotlib, it was still saying that 0.91 was the
latest and I couldn't install it. Finally I had to download the egg
and manually install it (easy_install --install-dir)

Jouni,
I found the error! I got bored this past weekend and changed my
mathtext.fontset to 'stixsans' just to see hopw it would look -- and then
forgot about it. Changing that value back to 'cm' let's my original code and
pyTest.py run without errors.
I really appreciate your help with this

Thanks for the reply. I found that I had (on a whim) set my mathtext.fontset to

In short, I'm all squared away now. Thanks!

Thanks. On further investigation, I was reminded that stixsans (or
anything not in the BMP) doesn't work with Type 42 fonts. The way the
PDF spec forces you to deal with them, if it's even possible, is really
hairy. So to solve your problem you can either a) not use stixsans, or
b) use Type
First of all, I recommend you to use spines instead of SubplotZero of
axes_grid toolkit.
http://matplotlib.sourceforge.net/examples/pylab_examples/spine_placement_demo.html
If you use axes_grid toolkit, keep in mind that some axis-related
command of matplotlib may not work. Please take a look
