# `pygfplots`: High quality plots with pgfplots and Python

The aim of this package is to make it easier to create nice looking graphs using data from Python programs.

Here is a (rather advanced) example of that, which serves as a documentation of this package:

```python

import numpy as np

xs = np.linspace(-1, 1, 300)

p = Pgf('$x$', '$T(x)$')

p.append('axis_options', 'cycle list name=color list')

p.append('axis_options', 'legend pos=outer north east')

p.append('axis_options', 'title={Chebyshev Polynomials}')

from numpy.polynomial.chebyshev import Chebyshev

for n in range(8):

	f = Chebyshev([0]*n+[1])

	p.plot(xs, f(xs), legend='$T_{0}$'.format(n), options=['smooth', 'thick', 'opacity=.6'])

p.append('tikz_header', r'\tikzset{>=stealth}')

p.append('footer', r'\path[draw=gray, thick] (axis cs:-1,-1) -- (axis cs:-1,1) -- (axis cs:1,1) -- (axis cs:1,-1) -- cycle;')

p.append('footer', r'\node[shape=circle, draw, fill opacity=.5, fill=white] (zero) at (axis cs:-.5,-.5) {};')

p.append('footer', r'\node[right, opacity=.8, fill=white, text opacity=1, draw=gray] (zero_label) at (axis cs:-.5,.5) {Interesting point};')

p.append('tikz_footer', '\draw[->,very thick] (zero_label) to[out=180,in=150] (zero);')

p.save() # for interactive visualisation

p.save('example') # to save to a tex file "example.tex"

```

The result produced is

![Chebyshev plot](https://github.com/olivierverdier/pygfplots/raw/master/images/cheb.png)

The general structure of the template is

```tex

\documentclass{standalone}

\usepackage{pgfplots}

\pgfplotsset{compat=1.5.1}

$tikz_header

\begin{document}

\begin{tikzpicture}

[$tikz_options

]

\begin{axis}

[$axis_options

]

$_contents

$footer

\end{axis}

$tikz_footer

\end{tikzpicture}

\end{document}

```
