matplotlib-users Mailing List for matplotlib

(Sorry, I submitted this email with a real figure instead of a toy
example and the file size was too big and it awaits moderator
approval).
I am afraid I asked you to open a can of worms and now I don't know
what we should do. With my font size settings, \small looks to small
for the exponents. I tried \normalsize and actually got decent
results with \large (replacing all occurances of \small in your
ticker.py). See that attached file. But if \small looked good with
your settings, I am afraid things are now dependent on the font
settings in the rc file as far as what should go in the latex command
for the exponents.
I remember that this problem came up because I complained about serif
fonts in my exponents and we were having a hard time making tex use
sans serif math fonts.
Maybe the best solution is for me to go back in time and retract that complaint.
I don't know. Sorry about the mess this had made. I have plots I am
fairly happy with (I will poke around in my rc file and see if I can
find out why my x and y axis fonts look different).

I didnt mean to come across so terse, I'm just really busy at work these days. 
So don't worry about it. I'm finishing a paper and am glad you caught the bug 
before I submitted the final draft.

This is an artifact that was introduced when I tried to give you support for 
sans-serif fonts in the exponent. Try the attached ticker.py, it wraps the 
exponent in {\small}. Let me know if this is acceptable, and I'll commit it.

I still have the problem with large exponents with your matplotlibrc
file (but the y-axis plots are no longer different).
Any thoughts on what I should try next?

There was a lot of stuff in my tex.cache, but deleting didn't solve my problem.
I may have some strange choices for my fonts and font sizes. Can you
send me a copy of your matplotlibrc file.

Hi Ryan,
I'm using the latest svn as well (2479), and I cant reproduce your problem. 
Try deleting your tex.cache.

I am having a problem with the fonts for exponents on semilog plots with usetex.
The attached figure can be generated on my machine with
figure(1)
t=arange(0,10,0.01)
y=sin(2*pi*t)
semilogx(t,y)
I just upgraded to the latest svn and now the y-axis plots look
different from the x-axis.
matplotlib.__version__
Out[6]: '0.87.3'

Erik,
I don't know of any solution with the old version, but there is a new 
version of quiver in svn; with it, your example produces

Hi,
due to limited white space in my figures, I would like to be
able to split up a single big legend into multiple (usually 2) smaller ones.
###############################
Example (adapted from simple_plot.py):
from pylab import *
t = arange(0.0, 2.0, 0.01)
s = sin(2*pi*t)
plot(t, s, linewidth=1.0)
s = sin(4*pi*t)
plot(t, s, color='r',linewidth=1.0)
grid(True)
mylegend = legend(('Graph 1','Graph 2'),
 loc='lower right',axespad=0.07,labelsep=0.04)
# modify legend
mylegend.draw_frame(False)
mylegendtext = mylegend.get_texts()
mylegendlines = mylegend.get_lines()
setp(mylegendtext, fontsize=15)
setp(mylegendlines, linewidth=1.2)
show()
##############################
I would like to split the legend up to into two.
One for "Graph 1" and one for "Graph 2" to be
able to place them where white space is available.
Is there an easy way to do this in matplotlib?
Thanks.

Charlie,
Any chance you will be posting soon a pkg installer for OSX for numpy 
0.9.8 and matplotlib 0.87.3?
If not do numpy 0.9.8 and matplotlib 0.87.3 build out of the box now 
from source?

<P>When I do a plot with quiver, I get very fat vectors - the arrow head le=
ngth is about 0.1 times the total height of the plot. If I do the following=

<P>- it is very difficult to see the single vectors because they are overla=
pping. I have tried different values of "width" in the call to quiver (e.g.=
 width=3D0.1), but this has no effect. </P>=0D
