3.12.3 SurfA

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

C function: void mgl_surfa_xy (HMGL gr, const HMDT x, const HMDT y, const HMDT z, const HMDT c, const char *sch)

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 (C++, Python): void SurfA (const mglData &z, const mglData &c, const char *sch="")

C function: void mgl_surfa (HMGL gr, const HMDT z, const HMDT c, const char *sch)

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