Enter the horizontal display range.
Enter the vertical display range.
Enter the horizontal range of the input sampling grid,
corresponding to the first independent variable (entered
in IHDEP).
Enter the vertical range of the input sampling grid,
corresponding to the second independent variable
(entered in DEF'ND).

Parametric Surface Plots
The Pr-Surface plot type draws an oblique-view, perspective,
3D plot of a wire-frame model of the surface determined by
F{u, v) = x(u, r:)i + yiu, t))j -F z(w, ?;)k where u and v are drawn from
the sampling grid
( X X -
and
Y Y “
ranges). Pr-Surface combines the
coordinate-mapping approach of Gridmap with the three-dimensional
perspective plotting of Wireframe.
