3.9.1 Plot

These functions draw continuous lines between points. 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 Area, Step, Stem, Tube, Mark, Error, Belt. See section Plot sample, for sample code and picture.

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

The function draws continuous lines between points {x[i], y[i], z[i]} in 3D space.

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

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

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

The function draws continuous lines between 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 Plot2 (const mglData &a, const char *pen=NULL, float zVal=NAN)

The function draws continuous lines between 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 This function is obsolete – use Plot() and SubData() functions instead.

Method on mglGraph: void Plot3 (const mglData &a, const char *pen=NULL)

The function draws continuous lines between points {x[i], y[i], z[i]} in 3D space, 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 This function is obsolete – use Plot() and SubData() functions instead.
