3D Graphing 366
Note: If you enter a fractional number for xgrid or ygrid, it is rounded to the nearest whole
number | 1. The 3D mode does not have
scl Window variables, so you cannot set tick
marks on the axes.
Standard values (set when you select
6:ZoomStd from the „ Zoom toolbar menu) are:
You may need to increase the standard values for the grid variables (
xgrid, ygrid) to
ensure that enough points are plotted.
Note: Increasing the grid variables decreases the graphing speed.
Setting the Graph Format
The Axes and Style formats are specific to the 3D graphing mode.
Exploring a Graph
As in function graphing, you can explore a graph by using the following tools. Any
displayed coordinates are shown in rectangular or cylindrical form as set in the graph
format. In 3D graphing, cylindrical coordinates are shown when you use use:

xmin =
L10.
xmax = 10.
xgrid = 14.
ymin = L10.
ymax = 10.
ygrid = 14.
zmin = L10.
zmax = 10.
ncontour = 5.
