matplotlib 'markevery' is not translated into PGFPlots

[Duesterwald]

Plotting dense data with the 'markevery=' should result in plots where not all data points are drawn with a marker, as described in

http://matplotlib.org/api/lines_api.html#matplotlib.lines.Line2D.set_markevery

However, matplotlib2tikz does not regard this. It could be done using the 'mark repeat' option or even 'mark indices' (see PGFPlots manual pp. 179-180)

Minimal example:

import matplotlib.pyplot as pp
import matplotlib2tikz as m2t

pp.plot(range(10), range(10), marker='o', markevery=3)

m2t.save('mark.tikz')

gives the output

\begin{tikzpicture}

\begin{axis}[
xmin=0, xmax=9,
ymin=0, ymax=9,
axis on top
]
\addplot [blue, mark=*, mark size=3, mark options={draw=black}]
table {%
0 0
1 1
2 2
3 3
4 4
5 5
6 6
7 7
8 8
9 9
};
\end{axis}

\end{tikzpicture}

It should give something like

% The lastest updates can be retrieved from
% 
% https://github.com/nschloe/matplotlib2tikz
% 
% where you can also submit bug reports and leavecomments.

table {%
