The Backlit Gauge widget represents the associated tag's value as a photorealistic meter, displaying both labeled major divisions and unlabeled minor divisions, the dial of which fluctuates according to the tag's value.
The properties dialog for the Backlit Gauge widget:
Number of Major Divisions
Controls how many labeled divisions will be drawn around the meter. Each labeled division will also be drawn with a longer line.
Number of Minor Divisions
Controls how many unlabeled divisions will be drawn within each major division. Each minor division will be drawn with a shorter line.
Use tag’s scaled min and max values
If selected, the minimum and maximum range of the meter will be controlled by the tag's scaled minimum and maximum values
Minimum Value and Maximum Value
Used to set the smallest and largest values to display on the meter. By default, these values will match the tag’s scaled process values.
You can override those values to set your own scale range. For example, assume that you have a tag for which the minimum and maximum scaled process values are 20 and 80 respectively. Drawing this tag with a minimum value of 0 and a maximum value of 100 will result in a meter that shows a full range of numbers from 0 to 100, but whose needle will move only between 20 and 80.
