Vue CircularGauge Methods
beginUpdate()
Prevents the UI component from refreshing until the endUpdate() method is called.
The beginUpdate() and endUpdate() methods prevent the UI component from excessive updates when you are changing multiple UI component settings at once. After the beginUpdate() method is called, the UI component does not update its UI until the endUpdate() method is called.

getInstance(element)
getInstance is a static method that the UI component class supports. The following code demonstrates how to get the CircularGauge instance found in an element with the myCircularGauge ID:
// Modular approach
import CircularGauge from "devextreme/viz/circular_gauge";
...
let element = document.getElementById("myCircularGauge");
let instance = CircularGauge.getInstance(element) as CircularGauge;
// Non-modular approach
let element = document.getElementById("myCircularGauge");
let instance = DevExpress.viz.dxCircularGauge.getInstance(element);See Also
getSize()
Returns an object with the following fields.
- width
The width of the UI component in pixels. - height
