Drawing a 3D Graph
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.
Configuring 3D Graph View Window Parameters
Use the 3D Graph View Window to specify maximum and minimum values for the x -axis,
y -axis, z -axis, s -variable, and t -variable. You can also specify the number of lines you would
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” m
Before drawing a graph, be sure to first configure View Window parameters as required to
ensure proper display of the graph.
S ClassPad Operation
(1) On the application menu, tap .
• This starts up the 3D Graph application and displays the initial screen of the active 3D
Graph Editor window.
(2) Tap  to display the View Window dialog box.
(3) Tap the “3D” option button so the option is selected.
(4) Configure the View Window parameters as described below.
• Press A to move the cursor and input an appropriate value for each parameter.
