Quick Standard
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).
