3.9.6 Stem

These functions draw vertical lines from points to axis plane. The plots are drawn for each row if one of the data is the matrix. By any case the sizes of 1st dimension must be equal for all arrays x.nx=y.nx=z.nx. String pen specifies the color and style of line and marks (see section Line styles). By default (pen="") solid line with color from palette is used (see section Pallete and colors). See also Area, Bars, Plot, Mark. See section Stem sample, for sample code and picture.

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

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

The function draws vertical lines from points {x[i], y[i], z[i]} down to z = Org.z.

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

C function: void mgl_stem_xy (HMGL gr, const HMDT x, const HMDT y, const char *pen)

The function draws vertical lines from points {x[i], y[i]} down to y = Org.y in plane z=zVal (default in plane z=Min.z).

Method on mglGraph (C++, Python): void Stem (const mglData &y, const char *pen="")

C function: void mgl_stem (HMGL gr, const HMDT y, const char *pen)

The function draws vertical lines from points {x[i], y[i]} down to y = Org.y in plane z=zVal (default in plane z=Min.z), where x[i] values are equidistantly distributed in interval [Min.x, Max.x].
