9.12.3 SurfA (Python)

Method on mglGraph (Python): void SurfA (mglData x, mglData y, mglData z, mglData c, const char *sch=NULL)

The function draws surface specified parametrically {x[i,j], y[i,j], z[i,j]} and transparent it by matrix c[i,j]. String sch sets the color scheme. Previous color scheme is used by default. If string sch have symbol ‘#’ then grid lines are drawn. All dimensions of arrays z and c must be equal. The minor dimensions of arrays x, y, z should be equal x.nx=z.nx && y.nx=z.ny or x.nx=y.nx=z.nx && x.ny=y.ny=z.ny. Arrays x and y can be vectors (not matrices as z). Surface is plotted for each z slice of the data. See also Surf, SurfC, Surf3A, TileS. See section SurfA sample, for sample code and picture.

Method on mglGraph (Python): void SurfA (mglData z, mglData c, const char *sch=NULL)

The same as previous with x, y equidistantly distributed in interval [Min, Max].
