4.13 Dual plotting

These plotting functions draw two matrix simultaneously. There are 5 generally different types of data representations: surface or isosurface colored by other data (SurfC, Surf3C), surface or isosurface transpared by other data (SurfA, Surf3A), tiles with variable size (TileS), mapping diagram (Map), STFA diagram (STFA). By default (if absent) values of x, y, z are equidistantly distributed in axis range. The minor dimensions of arrays x, y, z, c should be equal. Arrays x, y (and z for Surf3C, Surf3A) can be vectors (not matrices as c). String sch sets the color scheme (see Color scheme) for plot. String opt contain command options (see Command options).

MGL command: surfc zdat cdat ['sch'='']

C function: void mgl_surfc_xy (HMGL gr, HCDT x, HCDT y, HCDT z, HCDT c, const char *sch, const char *opt): The function draws surface specified parametrically {x[i,j], y[i,j], z[i,j]} and color it by matrix c[i,j]. If string sch have symbol ‘#’ then grid lines are drawn. If string sch have symbol ‘.’ then plot by dots is produced. All dimensions of arrays z and c must be equal. Surface is plotted for each z slice of the data. See also surf, surfa, surf3c. See section SurfC sample, for sample code and picture.
