I Mathematica 6 I have a PolarPlot, e.g., a 4-leaved rose:
PolarPlot[Cos[2 theta], {theta, 0, 2 Pi}]
How can I fill the inside -- or, what I really want, just the leaf in
the right half-plane -- with some color?
I note that Filling does not seem to be an option for PolarPlot (or for
what would be almost as good, ParametricPlot).
I tried including the following (obtained by converting from :
Prolog->RegionPlot[(x^2 + y^2)^(3/2) <= x^2-y^2, {x,-0.02,1},{y,-1,1},
Frame->False, AspectRatio->Automatic]
However, that led to a mysterious error message:
$Aborted is not a Graphics primitive or directive.
(Perhaps because of an incompatibility of a Prolog with cartesian
coordinates inside a polar coordinate plot??)
