Then choose Zoom In from the View menu, or click on the Zoom
In button on the toolbar. The graph will rescale, expanding the
selected region to fill the plotting area. If the Zoom In command is used
on one of several graph panes in a single graph window, the horizontal
axis will be changed in all graph panes.
Choosing Undo Zoom will reverse the last zoom action
performed, whether by the above Zoom In command or the
following Zoom Out command. You can undo multiple zooms with
multiple Undo Zooms.
The Zoom Out command will double the range of both the x- and
y-axes.
Autoscale Once will change the scales so that the plotted curves
fill the graph area. The scaling only takes place for the current
range of data plotted. You can also click on the Autoscale Once button
on the toolbar.
Set Axes to Autoscale makes the automatic scaling of the currently
active graph permanent so that the graph scales itself automatically for
the current data and each subsequent range of data that is plotted. Both x
and y axes may be changed. The y axis will not necessarily include the
origin, so you may want to perform a more limited autoscale by clicking
the y axis and choosing Autoscale from Zero in the ensuing dialog.
