pypgf

A Python interface for creating LaTeX plots with Christian Feuersänger's PGFPlots and Till Tantau's PGF/TikZ package. This package is still at a very rudimentary stage, might change heavily in the future and lacks documentation. Right now, only Mac and Linux are supported.

Requirements

  • Python >= 2.6.0
  • NumPy >= 1.3.0
  • PIL
  • pdflatex
  • PGF/TikZ
  • PGFPlots >= 1.4.0

Example

from pgf import *
from numpy import *

plot(sin(linspace(-10, 10, 200)), 'r--')
plot(cos(linspace(-10, 10, 200)), 'b--')
legend('$\sin(x)$', '$\cos(x)$')
draw()

The draw() command at the end compiles the figure and tries to open it in a PDF viewer.

Troubleshooting

If draw() fails to show anything, have a look at settings.py and check whether the settings are appropriate for your environment.

Another possible cause might be an outdated PGFPlots package. Try to figure out the version installed on your computer using

cat $(kpsewhich pgfplots.sty) | grep pgfplotsversion

If the version number is lower than 1.4.0, download the latest version. To install the package, locate the old package files with kpsewhich pgfplots.sty and replace them with the downloaded files. Afterwards, run texhash. See the PGFPlots manual for further instructions.

If compilation succeeds for simpler figures but fails for more data-intensive figures, you probably need to increase the memory limits of your TeX distribution. Try locating your TeX distribution's texmf.cnf configuration file and increasing the memory limits. For example, set:

main_memory = 20000000
pool_size = 8900000
max_strings = 500000
hash_extra = 2000000

Other parameters might be relevant as well. After changing the parameters, you need to run fmtutil --byfmt latex. More information can be found in the PGFPlots documentation.
