Edit and Memos

CrossGraph

A plotting engine and a visual component that draw what MathParser computes: curves with their discontinuities, intersections and extrema, cartesian and polar systems, and surfaces z = f(x, y) with contour lines. The engine samples on worker threads, knows nothing about a canvas and builds headless; the component is a thin layer over it. Free Pascal 3.2.2 and newer builds it: the sort in CrossVision.Geometry that once needed function references is written out in the same unit. Delphi 10.2 Tokyo and newer builds it as well.
