| RenderFragment |
A collection of scales (UI fragments).
|
Use the Scales property to define a collection of scales in the Timeline view.
The following code snippet defines two time scales.
Note
If you set the view’s Duration property, its value should be greater than the result of multiplying Units by UnitCount (Units*UnitCount). Otherwise, an appointment’s duration may be displayed incorrectly.
