VTS Graphic Editor: Advanced Outline Properties

The 2 figures below show the advanced outline properties.  In addition to Color, you can also set the outline style to any of the 5 options shown, and the outline width to be any of 1 to 30 pixels wide.

 

Both Editor and width provide the option of control via tag or expression, in addition to selecting directly from the menu shown above.  This is controlled with the button shown circled in the figure below

Being able to adjust the outline width in response to a changing tag value may be useful if you are also setting the scaling property to adjust with a tag's value.  This will allow you to set a narrower outline when the scale values are small and a wider line when the scale values are large.
