Gradient Table The gradient table depicts the points that

define the gradient curve in a tabular format. From this table

you can change the duration and %B concentration of any

point on the curve. To do so, select new values for the gradient

points. Changes that you make to the table will be reflected in

the gradient plot area.

You can also change the number of points on the curve by

inserting or deleting rows in the table. To change the number

of points, first highlight a table cell or row. Then click the

appropriate Gradient Button for the action you desire.
