Is Matplotlib slower than Matplotlib?
Is Matplotlib slower than Matplotlib?
Text handling with matplotlib's LaTeX support is slower than matplotlib's very capable mathtext, but is more flexible, since different LaTeX packages (font packages, math packages, etc.) can be used. The results can be striking, especially when you take care to use the same fonts in your figures as in the main document.

Matplotlib’s pgf support requires a recent LaTeX installation that includes the TikZ/PGF packages (such as TeXLive), preferably with XeLaTeX or LuaLaTeX installed. TeX uses the backslash \ for commands and symbols, which can conflict with special characters in Python strings.

This page describes several ways to produce publication quality graphics with LaTeX.
This section describes a technique following the ["Cookbook/Matplotlib/UsingTex"] guidelines.
Here is the outline of the LaTeX file used to include the figure (example for `REVTeX4` for publication is APS physics journals with a two column format.)
\documentclass[prl,10pt,twocolumn]{revtex4}
\usepackage{graphicx} % Used to import the graphics
\begin{document}
%...
\begin{figure}[t]
\begin{center}
\showthe\columnwidth % Use this to determine the width of the figure.
\includegraphics[width=\columnwidth]{fig1.eps}
\caption{\label{fig:sin_cos} Plot of the sine and cosine functions.}
\end{center}
\end{figure}
%...
\end{document}

The first step is to determine the size of the figure: this way, when the graphic is included, it will not be resized, and the fonts etc. will be exactly as you set them rather than scaled (and possibly distored). This can be done in LaTeX by explicitly setting the width of the figure and using the `\showthe` command to print this width. (In the example above, the figure width is set to the `\columnwidth`.)
When the file is processed by LaTeX, look at the output. The example above produces the following output (Note: LaTeX will pause after the `\showthe` command, press enter to continue):
This is TeX, Version 3.14159 (Web2C 7.4.5)
LaTeX2e <2001/06/01>
...
> 246.0pt.
l.8 \showthe\columnwidth
% Use this to determine the width of the figure.
?
[1] (./tst.aux) )
...

Thus, the figure will be 246.0pt wide. There are 1 inch = 72.27pt (in [La]TeX), so this means that the figure width should be 3.40390 inches. The heigth depends on the content of the figure, but the golden mean may be used to make a pleasing figure. Once this is determined, the `figure.figsize` property can be used to set the default figure size.
#!python numbers=disable
fig_width_pt = 246.0 # Get this from LaTeX using \showthe\columnwidth
inches_per_pt = 1.0/72.27 # Convert pt to inches
golden_mean = (sqrt(5)-1.0)/2.0 # Aesthetic ratio
fig_width = fig_width_pt*inches_per_pt # width in inches
fig_height =fig_width*golden_mean # height in inches
fig_size = [fig_width,fig_height]

Since the figure will not be scaled down, we may explicitly set the font sizes.
#!python numbers=disable
'font.size' : 10,
'axes.labelsize' : 10,
'font.size' : 10,
'text.fontsize' : 10,
'legend.fontsize': 10,
'xtick.labelsize' : 8,
'ytick.labelsize' : 8,

With these smaller plot sizes, the default margins are not enough to display the axis labels, so we need to specify large margins. We do this with an explicit call to the `axes()` function. In this example, we only have one axis. The typeset LaTeX document will have whitespace on either side of the figure, so we do not need to include this in the figure. Thus, we keep just a bit of whitespace at the top and to the right so that the labels do not extend beyond the bounding box, and add more space to the bottom for the x label:
#!python numbers=disable
pylab.axes([0.125,0.2,0.95-0.125,0.95-0.2])

Here is the python file that generates the plots.
#!python
import pylab
from pylab import arange,pi,sin,cos,sqrt
fig_width_pt = 246.0 # Get this from LaTeX using \showthe\columnwidth
inches_per_pt = 1.0/72.27 # Convert pt to inch
golden_mean = (sqrt(5)-1.0)/2.0 # Aesthetic ratio
fig_width = fig_width_pt*inches_per_pt # width in inches
fig_height = fig_width*golden_mean # height in inches
fig_size = [fig_width,fig_height]
params = {'backend': 'ps',
'axes.labelsize': 10,
'text.fontsize': 10,
'legend.fontsize': 10,
'xtick.labelsize': 8,
'ytick.labelsize': 8,
'text.usetex': True,
'figure.figsize': fig_size}
pylab.rcParams.update(params)
# Generate data
x = pylab.arange(-2*pi,2*pi,0.01)
y1 = sin(x)
y2 = cos(x)
# Plot data
pylab.figure(1)
pylab.clf()
pylab.axes([0.125,0.2,0.95-0.125,0.95-0.2])
pylab.plot(x,y1,'g:',label='$\sin(x)$')
pylab.plot(x,y2,'-b',label='$\cos(x)$')
pylab.xlabel('$x$ (radians)')
pylab.ylabel('$y$')
pylab.legend()
pylab.savefig('fig1.eps')

An obvious solution is to greyscale convert your figure, but for readibility, adding dashes is often better.. This maybe implemented for an example of a SigmoidalFunctions with

To ensure that your graphics use exactly the same fonts as your document, you can have LaTeX generate and substitute the text for your graph using the psfrag package. This is a good option if you have problems with the `text.usetex` method (for example, if the appropriate fonts cannot be found.)
To do this, simply use plain text for the labels and then replace them using the psfrag package. Here are the modified files to make use of this method:
\documentclass[prl,10pt,twocolumn]{revtex4}
\usepackage{graphicx} % Used to import the graphics
\usepackage{psfrag}
\begin{document}
%...
\begin{figure}[t]
\begin{center}
\psfrag{sin(x)}{$\sin(x)$}
\psfrag{cos(x)}{$\cos(x)$}
\psfrag{x (radians)}{$x$ (radians)}
\psfrag{y}{$y$}
{\footnotesize % Replace tick-lables with smaller font.
\psfrag{1.0}{1.0}
\psfrag{0.5}{0.5}
\psfrag{0.0}{0.0}
\psfrag{-0.5}{-0.5}
\psfrag{-1.0}{-1.0}
\psfrag{-8}{-8}
\psfrag{-6}{-6}
\psfrag{-4}{-4}
\psfrag{-2}{-2}
\psfrag{0}{0}
\psfrag{2}{2}
\psfrag{4}{4}
\psfrag{6}{6}
\psfrag{8}{8}
\showthe\columnwidth % Use this to determine the width of the figure.
\includegraphics[width=\columnwidth]{fig2.eps}
} % Note that the psfrag commands only work in the top-most environment.
\caption{\label{fig:sin_cos} Plot of the sine and cosine functions.}
\end{center}
\end{figure}
%...
\end{document}

#!python
import pylab
from pylab import arange,pi,sin,cos,sqrt
fig_width_pt = 246.0 # Get this from LaTeX using \showthe\columnwidth
inches_per_pt = 1.0/72.27 # Convert pt to inch
golden_mean = (sqrt(5)-1.0)/2.0 # Aesthetic ratio
fig_width = fig_width_pt*inches_per_pt # width in inches
fig_height = fig_width*golden_mean # height in inches
fig_size = [fig_width,fig_height]
params = {'backend': 'ps',
'axes.labelsize': 10,
'text.fontsize': 10,
'legend.fontsize': 10,
'xtick.labelsize': 8,
'ytick.labelsize': 8,
'text.usetex': False,
'figure.figsize': fig_size}
pylab.rcParams.update(params)
# Generate data
x = pylab.arange(-2*pi,2*pi,0.01)
y1 = sin(x)
y2 = cos(x)
# Plot data
# Plot data
pylab.figure(1)
pylab.clf()
pylab.axes([0.125,0.2,0.95-0.125,0.95-0.2])
pylab.plot(x,y1,'g:',label='sin(x)')
pylab.plot(x,y2,'-b',label='cos(x)')
pylab.xlabel('x (radians)')
pylab.ylabel('y')
pylab.legend()
pylab.savefig('fig2.eps')

Another way to set the legend fonts after the legend has been drawn is to use, for example:
from matplotlib.font_manager import fontManager, FontProperties
font= FontProperties(size='x-small');
pylab.legend(loc=0, prop=font);

If you have very complex images such as high-resolution contour plots or three-dimensional plots, saving these to vector graphic formats like PDF or EPS can result in unacceptably large files (though with the ability for stunning zooms). One solution is to selectively convert parts of the plot (not the text labels) to a rasterized image. This can be done with the so-called "mixed-mode rendering" capability in recent versions of matplotlib. Here is an example as it should probably work:
#!python
from pylab import meshgrid, sin, cos, linspace, contourf, savefig, clf
x, y = meshgrid(*(linspace(-1,1,500),)*2)
z = sin(20*x**2)*cos(30*y)
c = contourf(x,y,z,50)
savefig('full_vector.pdf')
clf()
c = contourf(x,y,z,50,rasterized=True)
savefig('rasterized.pdf')

however, {{{contourf}}} currently does not support the {{{rasterized}}} option (which is silently ignored). Some other plot elements do however. I am looking into a solution for this. -- MichaelMcNeilForbes
