19. Reference Line

The user can draw a reference line on the double mass plot. This allows the user to determine how straight the double mass plot is.

To display the reference line, select the Draw option under the Reference Line menu. Move the mouse to the starting location then click and drag the mouse to the end location. The reference line will be drawn as you move the mouse. Only one reference line can be displayed on the plot. To move the reference line, simply draw it again.

To remove the reference line from the plot, select the Remove option from the Reference Line menu and the reference line will be removed.
