New description:
This ticket implements plot options to control the graphical display of
polygons:
{{{
def plot(self,
point={}, line={}, polygon={},
wireframe={}, fill={},
**kwds):
"""
Return a graphical representation.
INPUT:
- ``point``, ``line``, ``polygon`` -- Parameters to pass to
point (0d), line (1d), and polygon (2d) plot
commands. Allowed values are
* Python dictionary: Passed as keywords to the plot
commands.
* String or triple of numbers: The color. This is equivalent
to passing the dictionary ``{'color':...}``.
* ``None`` or ``False``: Switch off drawing of the
corresponding graphics options.
- ``wireframe``, ``fill`` -- Similar to ``point`` / ``line`` /
``polygon``, but ``fill`` is used for the graphics objects
in the dimension of the polytope and ``wireframe`` is used
for all lower-dimensional graphics objects.
- ``**kwds`` -- optional keyword parameters that are passed to
all graphics objectcs.
OUTPUT:
A graphics object.
TESTS::
sage: square = polytopes.n_cube(2)
sage: plt = square.plot()
sage: for p in plt:
... print p.options()['rgbcolor'], p
(0, 0, 1) Point set defined by 4 point(s)
(0, 0, 1) Line defined by 2 points
(0, 0, 1) Line defined by 2 points
(0, 0, 1) Line defined by 2 points
(0, 0, 1) Line defined by 2 points
(0, 1, 0) Polygon defined by 4 points
Draw the lines in red and nothing else::
sage: plt = square.plot(point=None, line='red', polygon=False)
sage: for p in plt:
... print p.options()['rgbcolor'], p
red Line defined by 2 points
red Line defined by 2 points
red Line defined by 2 points
red Line defined by 2 points
Draw vertices in red, no lines, and a blue polygon::
sage: plt = square.plot(point={'color':'red'}, line=False,
fill=(0,0,1))
sage: for p in plt:
... print p.options()['rgbcolor'], p
red Point set defined by 4 point(s)
(0, 0, 1) Polygon defined by 4 points
"""
