The Left Bar widget is used to display a tag's value as a horizontal bar, the length of which increases from the right towards the left as the tag’s value increases. When the tag’s value is at a minimum, the bar will be shown as a thin line at the right edge of its range. When the tag’s value reaches its maximum, the widget will be displayed as a rectangle, filling the range.
The graphic editor for the Left Bar widget:
Set Color
Opens the Select Color Dialog from which you can select a color for this object.
Low Scale Range and High Scale Range
In most cases, these fields will be display-only, showing the Scaled Process Data Min and Scaled Process Data Max values configured for the associated tag.
These fields become editable when the widget is used to display a function or Calculation tag. The most common use is to provide an output range of 0 to 100 (%) given a data source whose numbers do not match these values (perhaps ranging from 20 to 80, for example). Set the low scale range to the value expected from the data source when it is at its minimum and the high scale range to the value expected from the data source when it is at its maximum.
