Add Time (X) Reference Lines

Time Reference Lines are colored vertical lines that can be positioned anywhere within the range of X-values on the Data Graph.

These reference lines indicate the temperature values at the intersection of a Data Plot with each displayed reference line.

Important Information

This is available when in Engineer Mode.

To add Time Reference Lines to the Data Graph:

1)On the Profile menu, click Add Time (X) Reference Line.


2)Select the line color by clicking the line button below the label.


When a reference line is displayed on the Data Graph, the default label is the next number of reference line. For example if there is two reference lines displayed, the next default label will be 3. The software allows the user to rename the line by using the Name text box.

3)Click the OK command to accept the new settings or Cancel to quit the command.

Important Information

If a reference line is used in a Data Table calculation, the name of the reference appears in the header along with the parameter value. These parameters indicate units, date, time and relative position depending on the selected Time (X) Scale.


Feature Shortcut Cursor

This command can also be accessed by right-clicking the scale on the Data Graph and select Add Time (X) Reference from the shortcut menu.


To move an Time (X) Reference Line:

1)Position the mouse pointer over the a Time (X) Reference line.
2)When the mouse pointer becomes a mouse_pointer_(aero_split), click and hold the left mouse button to drag it left or right releasing the mouse button when the Time (X) Reference line is at the desired location.


When moving the selected Time (X) Reference line, it can be moved past other cursors to any location on the Data Graph.

When a Time (X) Reference line is moved to a new position, it snaps to the closest real Time (X) value. Notice on highly magnified graphs that the line jumps from point to point. The values in the Data Table are automatically updated to reflect the new position.
