plots
A parametric surface plot draws an oblique, 3-D plot of a wireframe model
of a surface determined by a complex-valued function. This plot type
combines the coordinate mapping approach of the gridmap plot (see page
4-22) with the 3-D perspective plotting of wireframe plots (see page 4-20).
The following example is a parametric surface plot of xcos(y)i -i- a'sin(y)j
