Using Parameters in Reference Lines

Parameters give you a way to dynamically modify a reference line, band, or box. For example instead of showing a reference line at a fixed location on the axis, you can reference a parameter. Then you can use the parameter control to move the reference line.

A list of parameters is available in the Value drop-down list in the Add Reference Line, Band, or Box dialog box. Select the parameter you want to use.

The reference line is drawn at the Current Value specified by the parameter. To open the parameter control, right-click (Control-click on a Mac) the parameter in the Data pane and then select Show Parameter Control. Use the parameter control to change where the reference line is drawn.
