VTS Graphic Editor: Visibility

Applies to:  Arc, Bitmap, Border, Chord, Ellipse, Line, Pie, Pipe, Polygon, Rectangle, Text

Control Levels Available:  None,   Advanced

Defaults to:  None

The default control level is "None".  In this case, "None" means that no external factor has been applied to the visibility, thus it is visible as drawn.

Note that, in the case of a shape such as a rectangle, if both the fill and the border are set to "None", the object will be invisible regardless of how the Visibility is set.  Having a visibility property in addition to being able to set color and fill to "None" allows you to set those values to something meaningful and still have the object vanish when conditions dictate that it should not be seen.

 

Visibility can be controlled by a tag, an expression or a parameter, as selected using the button shown circled in the figure below.

 

The example shown in the above figure uses a tag named “AI_001” to control the visibility. The rectangle will be visible whenever when AI_001’s value is greater than 0.
