setGraph() CATALOG
setGraph(modeNameString, settingString) ⇒ string
Sets the Graph mode modeNameString to
settingString, and returns the previous setting
of the mode. Storing the previous setting lets
you restore it later.
modeNameString is a character string that
specifies which mode you want to set. It must
be one of the mode names from the table
below.
settingString is a character string that
specifies the new setting for the mode. It
must be one of the settings listed below for
the specific mode you are setting.
setGraph("Graph Order","Seq")
¸"SEQ"
setGraph("Coordinates","Off")
¸"RECT"
Note: Capitalization and blank spaces are
optional when entering mode names.
