Template:UnitDisplay

When the signal's physical unit is displayed, it is represented as a white bar:

In the example, there are white markers above and below the bar, indicating the range corresponding to the value written in the bar. These markers may be missing; then the range corresponds to the height of the bar itself.

Finally, the physical unit may be displayed with a white marker attached to the bar:

This display is used for nonnegative signals. Here, the physical unit corresponds to the distance of the white marker to the signal's baseline.
