With “box zoom”, you draw a selection boundary around the area you 
would like to enlarge. This causes the selected area to be enlarged so 
it fills the entire graph display.
“Factor zoom” lets you specify a zoom factor for enlarging or reducing 
a graph. 
Use the [Factor] command to configure zoom factor settings, the 
[Zoom In] command to zoom in, and the [Zoom Out] command to 
zoom out. 
“Auto zoom” automatically configures View Window 
y-axis values and 
redraws the graph so it fills the Graph window along the 
y-axis. 
Return a graph to its original View Window settings
Executing this command adjusts View Window 
x-axis values so that 
they are identical to the 
y-axis values. 
Round View Window settings (xmin, xmax, xdot) to an appropriate 
number of decimal places and redraw the graph. 
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).
