3.10.11 Grid

Method on mglGraph: void Grid (const mglData &x, const mglData &y, const mglData &z, const char *sch=NULL, float zVal=NAN)

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. 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.

Method on mglGraph: void Grid (const mglData &z, const char *sch=NULL, float zVal=NAN)

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