To do this on the Graph window:
Do this:
Automatically configure settings so the Graph screen fills the entire
screen in accordance with the graph being drawn
Tap [Zoom] and then [Auto], or
tap
R
.
Return a graph to its original View Window settings
Tap [Zoom] and then [Original].
Adjust View Window
x
-axis values so that they are identical to the
y
-axis
values
Tap [Zoom] and then [Square].
Round View Window settings (
x
min,
x
max,
x
dot) to an appropriate
number of decimal places and redraw the graph
Tap [Zoom] and then [Round].
Make the value of each dot equal 1, which makes all coordinate values
integers
Tap [Zoom] and then [Integer].
Return View Window parameters to their settings prior to the last zoom
operation
Tap [Zoom] and then [Previous].
Return View Window parameters to their initial default (see “Initial
(Default)” under “View Window Preset Parameters” on page 102)
Tap [Zoom] and then [Initialize].
Redraw graphs using preset View Window parameter values
See “Using Quick Zoom” below.
Using Quick Zoom
The quick zoom commands on the [Zoom] menu draw a graph using preset built-in View Window parameter
values.
Note:
The values in the explanations below apply during the half-size view of the Graph window (which is the
initial default setting of the Graph & Table application). Tapping
r
on the icon panel will switch to the
full-screen view and change the View Window settings.

zoom command.
*2 Depending on the Basic Format Angle setting, executing Quick Trig changes the
x
scale setting to

Using Built-in Functions for Graphing

function, assign values to its coefficients, and graph the results.
