We need is a Curve Draw type, where the user provides both x and y as a function of another parameter.
Right now the Curve Draw functionality works best when the function y(x) is single valued. Any function where the derivative of y with respect to x is very large will be less suitable. So we would like to have an option where this behavior is not occurring.
Do you mean something like a polar mode? to graph as r(theta) instead of y(x)? Because that would be AWESOME!
