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
L
10
{
X
{
10 and
L
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.

(q) functions
automatically adjust window values for you; however, you can manually set window values using
the window
(p) menu. You can set minimum and maximum
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 (
Xscl
and
Yscl
).
In the
³
Try-It! 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 (p) values to see a different
perspective of the graph of
Y
1
=50X
.
Note:
The examples in the next section assume that the calculator has been reset to the default settings as described in
