The properties dialog for the Thermometer widget:

 

Tag

The Tag field displays the name and description of the tag that is associated with this widget. You can use this to select a different tag or parameter to use as the data source for this widget.

Options

Set the number of major divisions and minor divisions within each major division. Defaults to 10 and 5.

Choose whether to include the text used for engineering units within the gauge. Defaults to show units.

You can add a degree symbol to the engineering units when configuring the tag by holding down the Alt-key while typing 0176 on the numeric keypad. Release the Alt-key before typing the C or F.

Colorization

Use the color selector dialogs to set the color of the liquid, text and thermometer background. This widget does not use the Style Settings tag.

Scaling

If Use Tag Scaling is selected, the minimum and maximum range of the meter will be controlled by the tag's scaled minimum and maximum values.

Otherwise, 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.
