To do this on the Graph window:
Automatically configure settings so the Graph screen fills the entire
screen in accordance with the graph being drawn
Return a graph to its original View Window settings
Adjust View Window -axis values so that they are identical to the -axis
values
Round View Window settings ( min, max, dot) to an appropriate
number of decimal places and redraw the graph
Make the value of each dot equal 1, which makes all coordinate values
integers
Return View Window parameters to their settings prior to the last zoom
operation
Return View Window parameters to their initial default (see "Initial
(Default)" under "View Window Preset Parameters" on page 102)
Redraw graphs using preset View Window parameter values
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.

*1 Any View Window parameter that is not shown in the above table is unchanged when you execute a quick
zoom command.
*2 Depending on the Basic Format Angle setting, executing Quick Trig changes the scale setting to π/2 (for
Radian), 90 (for Degree), or 100 (for Grad). The following settings are applied based on the scale value:
min = –7.7 × scale, max = 7.7 × scale.
Using Built-in Functions for Graphing
Your ClassPad is pre-programmed with the commonly used functions listed below. You can recall a built-in
function, assign values to its coefficients, and graph the results.
