Sometimes it is useful to be able to draw a Trendline that is parallel to another line.
Each heading below corresponds to one of the option groups in the larger dialog window. For more details click on the relevant heading.
Drawing Options
You can select the Color of your Line by clicking on the colored square to the left of Line Color. You can also change the Style used to draw the Line to any of the defined values (Normal, Wide, Dashed, Dotted, Dash-Dot, Dash-Dot-Dot or Invisible) using the drop down list to the right of Line Style.
If you check Automatically Extend Using, your Trendlines will be extended to the edges of the overlay window using the color specified by clicking the colored square on the right.
Action/Reaction Lines
If you choose One Reaction Line for each Action Line, when you create a parallel on either side of your reference line, a second parallel will be drawn on the other side of the reference line at an equal distance.
If you choose Many Reaction Lines for each Action Line, when you create a parallel on either side of your reference line, many parallel lines will be drawn on the other side of the reference line using a spacing equal to the distance of the first parallel from the reference line.
These lines can be adjusted by Ctrl-clicking and dragging them.
The following items are common to all of the drawing tools. Click on a link for details (use the Back button to return here).
