5-3 Drawing a 3D Graph

This section explains how to draw a 3D graph, as well as how to change the angle of a graph

and how to rotate a graph.

Use the 3D Graph View Window to specify maximum and minimum values for the

-variable, and

like for drawing the grid.

• For the xgrid enter the number of lines you would like drawn within the interval from xmin

to xmax. For example, if xmin = −3, xmax = 3 and xgrid= 15, 15 almost vertical lines will be

used to display your graph. The ygrid lines will be almost horizontal.

• After drawing a 3D graph, pressing the = key cycles the 3D Graph [Axes] setting (page

1-9-8) in the following sequence: "Off" → "On" → "Box" → "Off", and so on.

Before drawing a graph, be sure to first configure View Window parameters as required to

ensure proper display of the graph.
