The Tickmark property on the WebGauge control is used to visually display the values on a scale of your Radial or Linear gauge. There are two types of tick marks:
minor tick marks
major tick marks
You can configure both of them to display 'ticks' at specific values. Major tick marks are usually larger than minor tick marks. They are configured to highlight every nth value on the scale.
You can customize the tick marks on your gauge using the Tickmark Layout tab of the Properties panel.
