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:
• Press „ô, simultaneously if in RPN mode, to access to the PLOT
SETUP window.
•
Change to
TYPE Wireframe.
• Press ˜ and type 'X+2*Y-3' @@@OK@@@.
•
Make sure that 'X' is selected as the
variables.
