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.
Zoom factors 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.

5. Change one or both zoom
factors.

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