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.
