LaTeX document and BoundingBox of an eps file created by matplotlib

Question

I am having a problem in including an eps file generated by matplotlib into a LaTeX document. The size of the figure does not seems to be recognized correctly, and the caption overlaps with the figure.

Please see the image below. This is the image of the latex document which includes figures generated by matplotlib. The LaTeX source file and the python source code for the plotting are shown further below.

========================

=======================

Figure 1. is overlapped by the caption. It seems that the LaTeX recognizes the figure to have a smaller size than the actual size.

Figure 2. is the same eps file as Figure 1., but the bb parameters were specified in includegraphics command in the LaTeX document. The BoundingBox of the eps file is %%BoundingBox: 18 180 594 612, and the bb parameters were set as bb=0 0 594 612. The first two values are changed to zero while the last two values are kept. Then, Figure 2. looks good. The size of the figure seems to be recognized correctly.

I did not have this type of problem in other computers so far, and I wonder what is causing the problem. I am not sure if is the problem of matplotlib or LaTex, and I would like to have suggestions about how to find the source of the problem.

The version of matplotlib package is 1.1.1rc, and OS is Ubuntu 12.04. I processed the LaTeX document by latex command and then dvipdfm command.

>>> import matplotlib
>>> matplotlib.__version__
'1.1.1rc'

This is the first paragraph of the text.
Today is a good day. 

\begin{figure}[ht]
\begin{center}
\includegraphics[width=.5\linewidth]{fig.eps}
\caption{This is the caption of the figure included without specifying bb parameters.}
\label{fig1}
\end{center}
\end{figure}

This is the second paragraph of the text written below the first figure environment.
Tomorrow will be a bad day.

\begin{figure}[hb]
\begin{center}
\includegraphics[bb=0 0 594 612, width=.5\linewidth]{fig.eps}
\caption{This is the caption of the figure included with the first two bb parameters set zero.}
\label{fig2}
\end{center}
\end{figure}

% Note that fig.eps has the following bounding box information.
% $ grep BoundingBox fig.eps 
% %%BoundingBox: 18 180 594 612

Here is the python source code used for plotting.

#!/usr/bin/python

import matplotlib.pyplot as plt

plt.plot([0, 1, 2], [0, 2, 4], '-b')
plt.savefig('fig.eps')

Answer 1

I tried your example and it worked with dvips instead . Afterwards a ps2pdf does the job. So maybe dvipdfm does something wrong with the bounding box.
