The compass indicator widget represents the associated tag's value as a needle that swings from the defined reference angle through a full circle in response the linked tag's value.
The properties dialog for the Compass Indicator:
Data source
The indicator must be linked to a tag before it can be grouped into a new meter as part of a tag widget. Also, a tag must be selected before the "Use tag's scaled min and max values" option can be chosen in the Scaling part of this dialog.
Select / Adjust / Clear Image
The image to be used for the needle. In general, the image should have a vertical orientation. The Adjust option opens the Adjust Image dialog.
Options
Offset from center: A vertical offset, allowing you to position the needle so that a portion is below the center.
Counter Clockwise: Controls the direction that the needle rotates in response to increasing tag values.
Reference angle: The angle that corresponds to both the tag's minimum and maximum scaled value. Angles are measured in degrees, clockwise from vertical.
Dampen movement: When selected, applies an animation effect to needle motion so that the image appears to sweep from one value to another rather than jumping immediately.
Color options
A complete selection of options for controlling the color and opacity of the selected image.
Scaling
Used to set the tag values corresponding to the minimum and maximum angles. It is recommended that you use the tag's scaled values.
