![wingauge's tickmark extent pane.](images/Tickmark_Extent_Pane_01.png)
The Extent pane determines the start and end point of the tick mark on the scale. This sets the length of the tick mark. In a Radial gauge the start and end values are measured from the center and in a Linear gauge the start and end values are measured from the left of the gauge.
Start — Set this value to an integer from 0 to 100. This value sets the start position of the tick mark.
End — Set this value to an integer from 0 to 100. This value sets the end position of the tick mark.
