Detailed Description

Abstract base class providing plot and labeling functionality for functions F:Y->X.

Override mpProfile::GetX to implement a function. This class is similar to mpFY, but the Plot method is different. The plot is in fact represented by lines instead of points, which gives best rendering of rapidly-varying functions, and in general, data which are not so close one to another. Optionally implement a constructor and pass a name (label) and a label alignment to the constructor mpProfile::mpProfile. If the layer name is empty, no label will be plotted.
