Procedure
Note: This dialog box is
similar to the Calculate
dialog box.
Note: If an item is not valid
for the current settings, it will
appear dimmed. You cannot
move the cursor to a
dimmed item.
Note: Plots defined with
column numbers always use
the last data variable in the
Data/Matrix Editor, even if
that variable was not used
to create the definition.
Tip: To use an existing list
variable for x, y, Freq, or
Category, type the list name
instead of the column
number.
