3.10.2 Fall

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

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

The function draws fall lines for surface specified parametrically {x[i,j], y[i,j], z[i,j]}. This plot can be used for plotting several curves shifted in depth one from another. String sch sets the color scheme. Previous color scheme is used by default. If sch contain ‘x’ then lines are drawn along x-direction else (by default) lines are drawn along y-direction. 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). Fall lines are plotted for each z slice of the data. See also Belt, Mesh, Tens, MeshNum (see section Other settings). See section Fall sample, for sample code and picture.

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

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

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