Hello,
I have been struggling with this all afternoon. I have a function which
generates an array of arrays:
y=[array([<f(x0)>]),array([<f(x1)>]),array([<f(x2)>])...]
and x=array([x0,x1,x2,...])
I want to plot the family of curves y=f(x).
plot(x,y[n]) where n is the nth array in y plots the correct curve,
however plot(x,y) and plot(x,y[:]) complain about mismatched array
dimensions.
Any suggestions?
Thanks,
Dave

It was a problem introduced by one of the external dependencies during the 
distillation process, that's why your old eps files still look the way they 
do. It was not a problem with the viewer. It looks like the problem was fixed 
in a recent ghostscript release, and I don't think the matplotlib mailing 
lists are an appropriate forum for discussing problems with ghostscript.

Young-Jin: 
You can't have two "show()"s in one script. Comment out the first one, 
and replace the "clf()" with "figure()" and all is well.
Or, use "draw()".
See http://matplotlib.sourceforge.net/faq.html#SHOW for details.

After doing some upgrades, I think I have more information about this
issue. In summary, the problem is fixed, but I think there are still
some questions as to the cause of the earlier problem. Currently, I
have:
GPL Ghostscript 8.61
pdftops version 3.02
pdfTeX 3.141592-1.40.3-2.2
If I use the scripts in the original email, then there is no problem.
That is, with facecolor='white', the resulting eps, dvi, ps, and pdf
all have a figure with a white facecolor.
Strangely, if I use an EPS from before my upgrades, the problem still
exists. This has the fortunate effect that I do not need to
regenerate all my images. In this situation, as described previously,
the eps file looks fine using gv (has a white facecolor). However,
the resulting dvi, ps, and pdf all have a figure with no
facecolor---and this behavior not consistent with edgecolor.
I am using the same version of matplotlib (before and after the
upgrade)... SVN Revision 3709...and python 2.5 as well. Since the
problem still occurs with particular EPS files....the problem
definitely must be with the EPS.
I don't know how the EPS file is constructed in matplotlib...does it
make use of external programs like gs (and thus, points the reason
back at EPS Ghostscript)? In case someone is interested in searching
for the source of the problem, I have attached:
1) good.eps (which has a white facecolor when included in a document)
2) bad eps (which has no facecolor when included in a document)
3) test.pdf (a demonstration of both images in one document)
4) test.tex (the source for test.pdf)
Thanks!

Great to know the problem is solved in your particular instance. In 
general, though, the font-finding algorithm is being a bit too strict. 
Currently there's no sense of "weighting of properties" in the way it 
looks up fonts -- it should probably do something to the effect that a 
match of the name is more important than a match in the weight. As it 
stands now, if it doesn't find an exact match it throws up its hands and 
just grabs the first available font... There is some experimental 
support for using fontconfig (the more-or-less standard way to look up 
fonts on Linux these days) in SVN of matplotlib -- hopefully by the next 
release some of these things will be worked out.

The problem is in this line:
 /usr/share/matplotlib/mpl-data/fonts/ttf/cmex10.ttf
That's Computer Modern "Extra Symbols" which is mainly comprised of 
characters for composing math equations -- there's no "letters" in there 
at all. When matplotlib doesn't find an exact match for a font, it's 
supposed to default to Vera Sans. In all your experimentation, did you 
perhaps delete the Vera Sans that comes with matplotlib? (It doesn't 
look like it was in the search path.) Restoring that file should at 
least remove the "gibberish" problem, but you still won't get the fonts 
you want. You'll (unfortunately) have to do like you did with Arial 
Unicode and set all the parameters correctly.
(You may need to delete your font cache in ~/.matplotlib/ttffont.cache 
as well.)
Cheers,
Mike

Michael,
Thank you. Interesting results:
With verbose.level set to debug-annoying, these lines look significant:
 findfont failed Arial Unicode MS, normal, normal 500, normal, 14.0
Could not match Arial Unicode MS, normal, normal. Returning
/usr/share/matplotlib/mpl-data/fonts/ttf/cmex10.ttf
Well, I played around with this a little more and found the problem!
The font.weight of 'medium' (500) is what could not be found. When I
switched font.weight to 'normal' (400) in matplotlibrc, it worked and
the graph was rendered with the correct glyph. (This worked for the
DejaVu Sans font, still no luck with Arial Unicode MS, but, that's
fine.)
So, problem solved, thanks again! :)
Here's something I noticed: When I copied ARIALUNI.TTF into
/usr/share/matplotlib/mpl-data/fonts/ttf/ and ran the test plot, all
the characters are gibberish. Actually, they are glyphs, but, the
wrong ones. The same thing happens if I copy Thyromanes .ttf files
into that directory, or if I put those files in the $TTFPATH
directory. In fact, it also happens if I copy andalemo.ttf, and that
font doesn't include extra unicode characters.
So, I'll paste the entire debug-annoying output that occurred when I
was getting the gibberish text on the plot at the end of this email.
As you can see, I set the font to a nonsense string to illustrate that
the problem occurs even if the extra font in the directory isn't being
requested. Also, I made sure that the extra font wasn't duplicated
anywhere else in the search path.
Cheers,

We can first try to track down whether the Arial MS Unicode font is 
getting picked up. In your matplotlibrc, can you add:
 verbose: debug-annoying
and send the output of your plot to the list? You'll see where it looks 
up the font and whether that lookup failed or not.
There have been a number of Unicode-related fixes in SVN since the 
0.90.1 release -- though most were in the PDF backend, not PS. One 
thing to try (don't know offhand whether it's working better or not) may 
be to use the Cairo backend to generate the PS and then use ps2epsi to 
get an EPS.
Cheers,
Mike

After installing matplotlib (matplotlib-0.90.1.win32-py2.5.exe) on 
Windows XP, the command "from pylab import *" results in an error 
message complaining that the file "_agg" is missing. Indeed there is no 
file "_agg.py" in the distribution, although a file "_agg.pyd" exists. 
Can anyone suggest how to solve this problem?

Hi everybody,
I tried:
>>> import pylab
>>> pylab.plot(["a", "b", "c"], [1, 2, 3])
ValueError: invalid literal for float(): a
Well, I expected that. I wrote this to just explain my trouble: printing
strings instead float along x-axes (a sort of mapping floats to strings...).
Writing that pylab.plot I mean that "a", "b", "c" were equalli spaced and
"a" --> 1, "b" --> 2, "c" --> 3. I think it could be a reasonnable command.
Is there something similar?
Long searches didn't satisfy my problem.
Anybody knows the solution?
Thanks
PS sorry for bad english

This is now fixed in svn 3904. The problem was not related to x versus 
y but was caused by incorrect handling of the reversed y axis (positive 
down instead of positive up). If the x axis were the reversed one, the 
same problem would occur.

Yes, it is one of those infamous error messages from the extension code 
in the transforms module.

It is probably a divide-by-zero error; but the real bug was elsewhere in 
the extension code, where the y-data-interval was erroneously set to 
zero when you tried to set the ticks.

Thanks for the good bug report, or more precisely, the good report of a 
bad bug.
I dimly recall some other email recently--maybe on 
matplotlib-devel--that may have been related. I think it was advocating 
a different method of keeping track of reversed axes. Maybe it was 
prompted by encountering the same problem you ran into.

Folks, I need your help. I'll explain a little further what happens.
Following is a test program,'test.py', and screen shot of the error
message. Here, 'test.py' is simple chart of sinusoidal function in
http://matplotlib.sourceforge.net/screenshots.html (simple_plot.py), but
have two of them in series. I tried Wolfgang's suggestion but it doesn't
help. Any idea?
Test.py:
from pylab import *
t =3D arange(0.0, 2.0, 0.01)
s =3D sin(2*pi*t)
plot(t, s, linewidth=3D1.0)
xlabel('time (s)')
ylabel('voltage (mV)')
title('About as simple as it gets, folks')
grid(True)
show()
clf()
t =3D arange(0.0, 2.0, 0.01)
s =3D sin(2*pi*t)
plot(t, s, linewidth=3D1.0)
xlabel('time (s)')
ylabel('voltage (mV)')
title('About as simple as it gets, folks')
grid(True)
show()
Execution of test.py:
c:\Python24>python test.py
c:\Python24\lib\site-packages\matplotlib\numerix\__init__.py:53:

This might help you it destroys the whole window:
pylab.get_current_fig_manager().destroy()
and then you open it again with show

It appears that IndexFormatter is no longer in ticker.py as the user guide
(Table 6.3, p.58) suggests.

Sorry, reposting, because I sent it from the wrong address.
