3.10.4 Surf

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

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

The function draws surface specified parametrically {x[i,j], y[i,j], z[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. 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 Mesh, Dens, Belt, Tile, Boxs, SurfC, SurfA. See section Surf sample, for sample code and picture.

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

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

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