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
3D Graph View Window parameters let you specify the maximum and minimum values for
the
x
-,
y
- and
z
-axis. 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
13-3-6) 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.
