 TIpË 5: Adjusting the Viewing Window
You can adjust the viewing window for a specific graph. For example, with the
ZStandard
viewing window default values of
/
10
^
X
^
10 and
/
10
^
Y
^
10, the graph of
Y
1
=50X
appears as
shown in the screen below on the left.
Y
increases so rapidly in relation to
X
that this line is not
easily seen in this window. You can adjust the window ( ' ) values by scaling the
X
axis and
Y
axis to see the graph in a better perspective.

automatically adjust window values for you; however, you can manually set window values
using the window

X
and
Y
values (
Xmin

Xmax, Ymin
, and
Ymax
), and you can set the scale (distance between tick marks) of the
X
axis
and
Y
axis (

example, you will adjust the viewing window values in two ways.
•
Automatically adjust them by selecting a zoom function from the
ZOOM
( ( ) menu.
•
Manually adjust them using the window ( ' ) menu.
In the example that follows, you see how to change window (
S
) values to see a different
perspective of the graph of
Y

.
