Numeric
Setup
Although you can configure
the X- and Y-values shown in
Numeric view by entering
values and zooming in or
out, you can also directly set
the values shown using
Numeric setup.
15. Display the Numeric
Setup view:
S
M
(Setup)
You can set the starting value and step value (that is, the
increment) for both the X-column and the Y-column, as well as
the zoom factor for zooming in or out on a row of the table.
You can also choose whether the table of data in Numeric
view is automatically populated or whether it is populated by
you typing in the particular x-values and y-values you are
interested in. These options—Automatic or
BuildYourOwn—are available from the
Num Type list. They
are explained in detail in “Custom tables” on page 103.
Trace in
Numeric
view
Besides the default configuration of the table in Numeric view,
there are other options available in the Trace menu. The trace
options in Numeric view mirror the trace options in Plot view.
Both are designed to help you investigate the properties of
relations numerically using a tabular format. Specifically, the
table can be configured to show any of the following:
• edge values (controlled by X or Y)
• points of interest (PoI):
– X-intercepts
– Y-intercepts
– horizontal extrema
– vertical extrema
– inflections
The values shown using the
Trace options depend on the Plot view window; that is, the
values shown in the table are restricted to points visible in Plot
view. Zoom in or out in Plot view to get the values you want to
see in the table in Numeric view.
