The Bar Marker property of the WinGauge control is used to point out values on a scale of your Linear or Radial gauge. A Bar Marker is displayed as bars that have a start and end point on the scale. For example, if you were creating a Linear gauge to represent a thermometer you would use a bar marker to display the mercury level.
You can customize the bar marker on your gauge using the Bar Marker Layout tab of the Properties panel. You can access this tab by either clicking Bar Marker in the Gauge Explorer (Gauge > Scales > Markers > Bar Marker) or clicking a bar marker on your gauge in the interactive preview area.
The tab is divided into three panes:
