To interpolate the Y value under the active cursor:

1.Set the cursor to the point on the curve whose Y value you want to interpolate.

2.Open the list box and click Cursor Tools/Cursors[Edit] > Edit Value and choose the command Interpolate Value.

3.In the dialog box that appears, enter a new Y value in the physical unit of the data upon which the curve is based.

To interpolate the Y values of all data between the cursors:

1.Set both cursors on the left and right edge of the area whose Y values you want to interpolate.

2.Open the list box and click Cursor Tools/Cursors[Edit] > Edit Range and choose the command Interpolate Range.

3.In the dialog box that appears, enter a new Y value in the physical unit of the data upon which the curve is based.

Note:   You can only manipulate data directly if the curve is based on a data set and not on a formula. If the curve is based on a formula, you first have to convert it into a data set.

The manipulation takes place directly in the data set and cannot be undone.
