Add Movable Line

Adds a brown movable line to the selected graph; the equation for the line is reported below the plot. The equation of the line dynamically updates as the line is moved.

Dragging near an end rotates the line, dragging near the middle moves it up or down (without changing its slope). In a univariate plot, the line can be moved left or right (up or down, if the attribute is on the vertical axis). The cursor changes shape to suggest what dragging will do at any given moment.

You can rechoose this command to add another movable line.
