Dear Frederic,
Would the options to contour_plot be of help? For instance,
sage: contour_plot?
<snip>
* ``cmap`` -- a colormap (default: ``'gray'``), the name of a
predefined colormap, a list of colors or an instance of a
matplotlib Colormap. Type: ``import matplotlib.cm;
matplotlib.cm.datad.keys()`` for available colormap names.
<snip>
* ``labels`` -- boolean (default: False) Show level labels or
not.
The following options are to adjust the style and placement
of
labels, they have no effect if no labels are shown.
* ``label_fontsize`` -- integer (default: 9), the font size
of
the labels.
* ``label_colors`` -- string or sequence of colors (default:
None) If a string, gives the name of a single color with
which
to draw all labels. If a sequence, gives the colors of the
labels. A color is a string giving the name of one or a
3-tuple of floats.
* ``label_inline`` -- boolean (default: False if fill is
True,
otherwise True), controls whether the underlying contour is
removed or not.
If there are additional things in Matplotlib we have not wrapped which
you could use here, we would be very interested in hearing this.
On the other hand, if you truly want to specify the color of a
specific point, you would have to create Point or Line objects and use
the color or rgbcolor keywords. But it sounds like what you are
looking for is a contour plot, or possibly also implicit_plot3d (in
the latter case, you would specify a different color for each contour
you implicitly plot, and then add the graphics together before viewing
it). At any rate, the documentation for all the plotting functions
should answer many of your questions.
If I've interpreted your question incorrectly, please let us know!
Good luck.
