Recent messages under the subject "shading implicit plot" discussed the
use of the option ColorFunction with the ImplicitPlot package. I was
surprised ImplicitPlot uses the ColorFunction option because it isn't
included in the list returned by Options[ImplicitPlot].
After studying the code for the package and doing some investigating I
found other options ImplicitPlot can use. In particular ImplicitPlot
will take the options ColorFunction, Compiled, ContourLines,
ContourShading, ContourStyle, FormatType, ImageSize, and TextStyle even
though they aren't returned by Options[ImplicitPlot]. Use of each of
these options except Compiled is demonstrated below.
In[1]:=
<<Graphics`ImplicitPlot`
In[2]:=
ImplicitPlot[x^2+y^2==1/2,{x,0,0.75},{y,0,0.75},ContourStyle->Dashing[{0.02,
0.02}],
TextStyle->{FontColor->Hue[0.7]}]; (* Graphic not shown *)
In[3]:=
ImplicitPlot[x^2+y^2==1/2,{x,0,0.75},{y,0,0.75},
ColorFunction->(If[#<0.5, GrayLevel[0.7], GrayLevel[1]]&),
ImageSize->{200,200}, ContourLines->False,
ContourShading->True];
(* Graphic not shown *)
ImplicitPlot[ArcSin[x]-y==0,{x,-1,1},{y,-p/2,p/2},
PlotLabel->HoldForm[ArcSin[x]=y],
FormatType->TraditionalForm];
(* Graphic not shown *)
I have yet to find documentation indicating that ImplicitPlot uses these
options.
Cheers,
