You will obtain better responses if you supply a completely evaluable
example and not leave it up to responders to make up part of the input.

Hi there
I am a bit stuck with this one. I have several curves (circles in this
case) I want to plot at the same time. Each circle also has its own function
defining a unique potential as a function of theta around the curve. I want
to take advantage of Mathematica's colorfunction color scaling and show the
potential around each curve in a color scaled to the min and max values for
the entire set of circle potentials. I get about this far....
n = 5; (*number of circles*)
potential[theta_, i_] := Sin[2*i*theta];
circle[i_, theta_] := {x[i] + r[i]*Cos[theta], y[i] + r[i]*Sin[theta]};
(*x,y, and r are earlier defined vectors of coordinates, radius*)
ParametricPlot[
Evaluate@Table[circle[i, theta], {i, 1, n}], {theta, 0, 2 Pi}, PlotStyle
-> Thick, Axes -> False, ColorFunction ->
Function[{x, y, theta}, ColorData["TemperatureMap"][theta]]];
I can get a nice rainbow color around each circle but it is the same for
all because I can only seem to define one colorfunction and cannot
incorporate the potential function which varies for each circle "i".
Any help would be most appreciated.
