This command makes the value of each dot equal 1, which makes all
coordinate values integers.
Performing a zoom operation changes View Window parameter
values. Execute this command to return View Window parameters to
their settings prior to the last zoom operation.
These seven quick zoom commands cause the graph to be redrawn
using preset View Window parameter values (page 3-2-9).
