## Wireframe plots

Wireframe plots are plots of three-dimensional surfaces described by z = f(x,y).
Unlike Fast 3D plots, wireframe plots are static plots. The user can choose the
viewpoint for the plot, i.e., the point from which the surface is seen. For
example, to produce a wireframe plot for the surface z = x + 2y –3, use the
following:

Keep the default plot window ranges to read:
Far: 1, Z-Low: -1, Z-High: 1, XE:0,YE:-3, ZE:0, Step Indep: 10 Depnd: 8
The coordinates XE, YE, ZE, stand for "eye coordinates," i.e., the coordinates
from which an observer sees the plot. The values shown are the default values.
The Step Indep: and Depnd: values represent the number of gridlines to be used
in the plot. The larger these number, the slower it is to produce the graph. For
the time being we'll keep the default values of 10 and 8 for the Step
