40 \subsection{Label} |
|
41 Pylab accepts TeX equation expressions in any text expression. To get something like:\\ |
|
42 $\sigma_i=15$ \\ |
|
43 on title of figure use: |
|
44 \begin{lstlisting} |
|
45 title('$\sigma_i=15$') |
|
46 \end{lstlisting} |
|
47 Same way one can have TeX expression on xlabel, ylabel etc. |

49 \subsection{legends} |
|
50 Apart from using \kwrd{loc='center'} for positioning the legend, one can also mention explicit co-ordinates for placement. |
|
51 \begin{lstlisting} |
|
52 In []: legend(['sin(2y)'], loc=(.8,.1)) |
|
53 \end{lstlisting} |
|
54 \typ{loc = 0, 1} (left top position of graph)\\ |
|
55 \typ{loc = 0.5, 0.5} (center of graph). |

|
60 One can save figure in any of these formats: png, pdf, ps, eps and svg. |
