Hi all,
I have been trying to follow your tips regarding matplotlib and arabic support.
Indeed matplotlib with Latex and unicode work great together :
#-*- coding: utf-8 -*-
from pylab import *
from matplotlib import rcParams
rcParams['text.usetex']=True
rcParams['text.latex.unicode']=True
figure(1)
plot([1,2,3])
title(unicode(r'\textit{éèê}','utf8'))
show()
But then I came to the conclusion that Latex did not support Arabic.
This few lines generate a "missing def" error.
\documentclass{article}
\usepackage{ucs}
\usepackage[utf8x]{inputenc}
\title{éèê هه}
\begin{document}
\maketitle
\end{document}
Is it related to my installation ? (Ubuntu with package
texlive-latex-recommended)
I asked here : http://ubuntuforums.org/showthread.php?p=5258457
Somebody pointed me out XeTeX, which has wider support for Unicode.
www.tug.org/TUGboat/Articles/tb27-2/tb87kew.pdf
I was wondering if there could be a way to get matplotlib work with XeTeX.
What do you think ? Is it the right track ? Should I switch to
grandpa's gnuplot :) ?
Thank you all,
Mathieu.
