3.10.10 ContD

Method on mglGraph (C++, Python): void ContD (const mglData &v, const mglData &x, const mglData &y, const mglData &z, const char *sch="", float zVal=NAN)

C function: void mgl_contd_xy_val (HMGL gr, const HMDT v, const HMDT x, const HMDT y, const HMDT z, const char *sch, float zVal)

The function draws solid (or filled) contour lines for surface specified parametrically {x[i,j], y[i,j], z[i,j]} at z = zVal (or for z=v[k] if zVal==NAN) with manual colors. Contours are plotted for z[i,j]=v[k] where v[k] are values of data array v (must be v.nx>2). String sch sets the contour colors: the color of k-th contour is determined by character sch[k%strlen(sch)]. 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). Surface is plotted for each z slice of the data. See also Dens, Cont, ContF. See section ContD sample, for sample code and picture.
