The following table details the fields on the Numeric Setup input form.

Field	Meaning

NUMSTART	The independent variable’s
	starting value.
NUMSTEP	The size of the increment from
	one independent variable value
	to the next.
NUMTYPE	Type of numeric table: Automatic
	or Build Your Own. To build your
	own table, you must type each
	independent value into the table
	yourself.
NUMZOOM	Allows you to zoom in or out on a
	selected value of the independent
	variable.

To reset the default values for all table settings, press
