Plot view functionality that is common to many apps is described in detail in this section. Functionality that is available only in a particular app is described in the chapter dedicated to that app.

Press Pto open Plot view.

[Scope: Advanced Graphing, Function, Parametric, Polar, Sequence, Solve, Statistics 1 Var, and Statistics 2Var. Also, to a limited degree, Geometry.]

Zooming redraws the plot on a larger or smaller scale. It is a shortcut for changing the range settings in Plot Setup view. The extent of most zooms is determined by two zoom factors: a horizontal and a vertical factor. By default, these factors are both 2. Zooming out multiplies the scale by the factor, so that a greater scale distance appears on the screen. Zooming in divides the scale by the factor, so that a shorter scale distance appears on the screen.

To change the default zoom factors:

1.Open the Plot view of the app (P).

2.Tap to open the Plot view menu.

3.Tap to open the Zoom menu.

4.Scroll and select Set

Factors.

The Zoom Factors screen appears.

5.Change one or both zoom factors.

6.If you want the plot to be

centered around the current position of the cursor in Plot view, select Recenter.

7.Tap or press E.

Zoom options are available from three sources:

•the keyboard

•the menu in Plot view

•the Views menu (V).
