[Matplotlib-users] imshow problem

[Luigi P. <lu...@mi...>]

Hi all!

I've just installed matplotlib on my workstation (without Numeric, only 
numarray). Trying to run the image plot examples, I get this error:


Exception in Tkinter callback
Traceback (most recent call last):
   File "<mypath>/lib/python2.3/lib-tk/Tkinter.py", line 1345, in __call__

What's the problem?

Tanks in advance.

[Matplotlib-users] missing ticks and TeX symbols

[Steve S. <el...@gm...>]

Hi

I did some plots (MPL 0.82 on Linux), exported them as .eps 
\includegraphics'ed them in TeX (latex -> dvipdf).
Some plot labels included r'$\tau$' and things like that. Unfortunately 
when I print my document the TeX symbols are missing. Moreover the 
x-axis tick numbers as well as the xlabel are also not there. I know 
other people who also had problems with missing or screwed up symbols 
when printing out .pdfs (unrelated to TeX, MPL). Is there anything I can 
do about that from the MPL side?

cheers,
steve

1. If you view the EPS, say in GhostScript, is everything 
   there?
2. What is the bounding box (if you look in the EPS file)?  
   Is it all inside the page dimension set in your dvipdfm 
   config file?

Cheers,

1.) yes, the plots are fine

2.) yes, the bounding box is large enough

I attached one of the .eps files I was talking about. In the printed 
.pdf where this is included the xlabel "T/K" as well as the numbers on 
the x-axis are missing. The "x"s in the legend box are also missing so 
it isn't a bb problem.

I used dvipdf to convert .dvi -> .pdf (which I've learned only uses 
dvips and gs with some pdfwrite options) and not dvipdfm. Is it 
recommended to use dvipdfm over dvipdf?

cheers,
steve

Works fine with dvipdfm.
(Ticks and labels are visible.)

Thanx. When I look at the .pdf on the screen everything is fine. Only
the printed version is the problem. I'll test (on Linux) if the printer
likes the .pdf produced by dvipfdm more than the output of dvipdf.
