# Animation
## Content
By default, when the `Value` of a gauge is changed, the pointer animates smoothly from the old value to the new one. This provides a natural, fluid transition between values.
In cases where this animation is not desired — for example, when values update very frequently or need to reflect changes instantly — set `IsAnimated="False"` to disable all animation. Value changes will then appear immediately without any transition.
### Customizing the Animation
The `UpdateAnimation` property allows you to customize the animation behavior when the gauge value changes. You can configure:
| @cols=1:**Property** | @cols=1:**Description** |
| -------- | ----------- |
| @cols=1:@rows=1:`Duration` | @cols=1:@rows=1:How long the animation takes to complete. |
| @cols=1:@rows=1:`StartDelay` | @cols=1:@rows=1:A delay before the animation begins. |
| @cols=1:@rows=1:`Easing` | @cols=1:@rows=1:The easing function that controls the acceleration curve of the animation. |
For example, the **Clock** sample demonstrates how to customize the easing so the seconds hand moves more realistically, using an `ElasticEase` to simulate the mechanical bounce of a real clock:
```auto
clockSecs.UpdateAnimation.Easing = new ElasticEase() { Oscillations = 1, Springiness = 4 };
```

> **Note:** `IsAnimated` is `true` by default. Setting it to `false` disables both the default animation and any custom `UpdateAnimation` configuration.
