3.9.7 Step

These functions draw continuous stairs for 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=NULL) solid line with color from palette is used (see section Pallete and colors). See also Plot, Stem, Tile, Boxs. See section Step sample, for sample code and picture.

Method on mglGraph: void Step (const mglData &x, const mglData &y, const mglData &z, const char *pen=NULL)

The function draws continuous stairs for points {x[i], y[i], z[i]}.

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

The function draws continuous stairs for points {x[i], y[i]} in plane z=zVal (default in plane z=Min.z).

Method on mglGraph: void Step (const mglData &y, const char *pen=NULL, float zVal=NAN)

The function draws continuous stairs for points {x[i], y[i]} in plane z=zVal (default in plane z=Min.z), where x[i] values are equidistantly distributed in interval [Min.x, Max.x].

Method on mglGraph: void Step2 (const mglData &a, const char *pen=NULL, float zVal=NAN)

The function draws continuous stairs for points {x[i], y[i]} in plane z=zVal (default in plane z=Min.z), where x=a(2*k,:), y=a(2*k+1,:), k \in 0 ... a.ny/2. This function is obsolete – use Step() and SubData() functions instead.

Method on mglGraph: void Step3 (const mglData &a, const char *pen=NULL)

The function draws continuous stairs for points {x[i], y[i], z[i]}, where x=a(3*k,:), y=a(3*k+1,:), z=a(3*k+2,:), k \in 0 ... a.ny/3. This function is obsolete – use Step() and SubData() functions instead.
