The MinValue and MaxValue properties together define the range of values allowed for the ArcScale. The current value indicated by the needle is specified by the Value property.
Note that the MaxValue property value needn't necessarily be greater than the MinValue. For instance, if you switch their values, this will simply change a circular scale's direction.
MinValue = 0, MaxValue = 100 (Default) |
MinValue = 100, MaxValue = 0 (Rotated) |

While the MinValue and MaxValue properties define the limit values, the number of tickmarks (and therefore labels) between them is specified by the MinorTickCount and MajorTickCount properties. The following images demonstrate how these properties can be modified together to customize the circular scale.
Default
|
MinValue = 0, MaxValue = 12
|
MinValue = 0, MaxValue = 12,
MinorTickCount = 1, MajorTickCount = 13

To specify the angles where the scale starts and ends, use the StartAngle and EndAngle properties.
