I used a Linear Scale Component using Ignition 7.8 to display a fuel level like this:
I want to indicate the current value of the fuel in the same scale. But as I browse through the property of the Linear Scale Component, I couldn't any property resembling Value, Text, Number, or alike.
How can I display the Value in it?

Create a data set for that component that includes an indicator arrow or line. Then, use Cell Bindings to bind a tag to that indicator arrow.
