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.

After calling this method, remove the DOM element associated with the UI component:

$("#mySparkline").dxSparkline("dispose");
$("#mySparkline").remove();

Use this method only if the UI component was created with jQuery or pure JavaScript. In Angular, Vue, and React, use conditional rendering:

<dx-sparkline ...
    *ngIf="condition">
</dx-sparkline>

<template>
    <DxSparkline ...
        v-if="condition">
    </DxSparkline>
</template>

<script>
import DxSparkline from 'devextreme-vue/sparkline';

export default {
    components: {
        DxSparkline
    }
}
</script>

import React from 'react';

import Sparkline from 'devextreme-react/sparkline';

function DxSparkline(props) {
    if (!props.shouldRender) {
        return null;
    }

    return (
        <Sparkline ... >    
        </Sparkline>
    );
}

class App extends React.Component {
    render() {
        return (
            <DxSparkline shouldRender="condition" />
        );
    }
}
export default App;

getInstance is a static method that the UI component class supports. The following code demonstrates how to get the Sparkline instance found in an element with the mySparkline ID:

// Modular approach
import Sparkline from "devextreme/viz/sparkline";
...
let element = document.getElementById("mySparkline");
let instance = Sparkline.getInstance(element) as Sparkline;

// Non-modular approach
let element = document.getElementById("mySparkline");
let instance = DevExpress.viz.dxSparkline.getInstance(element);

Normally, the UI component redraws itself automatically after the browser window is resized. But on rare occasions, you may need to request the redrawing, for example, after the UI component's container is resized. For this purpose, call the render() method.
