Advanced cursor options
The options in the Advanced area of the Cursor dialog box includes options that place the selected
cursor at special locations on the graph.
After the cursor moves to the option you selected, the option is cleared and you can manually position
the cursor.
You can select the following options:
The Align to <CursorNumber> and Lock to <CursorNumber> check box options are enabled only
when both cursors 1 and 2, both cursors 3 and 4, or both cursors 5 and 6 are active.
•
Go To MAX:
Places the cursor at the maximum-Y data point of the plot to which the cursor is
attached.
•
Go To MIN:
Places the cursor at the minimum-Y data point of the plot to which the cursor is
attached.
•
Align to #:
Aligns the cursor to the same X axis value as the next cursor. The Align To option is
disabled if a subsequent cursor is not available (Visible is cleared).
•
Lock to #:
Locks the position of the cursor relative to the position of the next cursor. For
example, the next cursor is cursor 3 if the first is 2. The cursor tracks the movement of the next
cursor, and the relative X distance between the two cursors remains constant. Note that the next
cursor does not track the movement of the previous cursor. The Lock To option is disabled if a
subsequent cursor is not available (Visible is cleared).
•
Fit On:
For information on the Fit On options, see
(on page 6-205).
Line fits between cursors
You can fit lines to test result graphs for one or two line fits between existing cursors. When the line is
fitted, the graph displays:
•
The fitted line.
•
The fit parameters.
•
The data point at which a tangent line is fitted to the plot or the starting and ending data points
(data range).
•
The data-point coordinates. Tangent or starting and ending data points are defined by
cursors.
The results on the Graph line fits are similar to the results with the corresponding Formulator
functions, as shown in the table below.
