8.12.11 Grid (Pure C)

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

The function draws grid lines for density plot of surface specified parametrically {x[i,j], y[i,j], z[i,j]} at z = zVal. String sch sets the color scheme (see section Color scheme). Previous color scheme is used by default. 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). Grid is plotted for each z slice of the data. See also Dens(), Cont(), ContF().

C function: void mgl_grid (HMGL gr, const HMDT z, const char *sch, float zVal)

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