This section explains how to customize the sparkline with multiple range bands.

Range band customization

The range band feature is used to highlight a particular range along with the y-axis using the [startRange] and [endRange] properties. You can also customize the [color] and [opacity] of the range band.

import { Sparkline } from '@syncfusion/ej2-charts';

let sparkline: Sparkline = new Sparkline({
    height: '150px',
    width: '150px',
    lineWidth: 2,
    fill: '#0d3c9b',
    dataSource:   [0, 6, 4, 1, 3, 2, 5],
    // To configure range band settings
    rangeBandSettings: [
            {
                startRange: 1,
                endRange: 3,
                color: '#bfd4fc',
                opacity:0.4
            }
    ]
});
sparkline.appendTo("#element");

Multiple range band customization

You can define multiple range bands to a sparkline as shown in the following code sample.

import { Sparkline } from '@syncfusion/ej2-charts';

 let sparkline: Sparkline = new Sparkline({
    height: '150px',
     width: '150px',
     lineWidth: 2,
     fill: '#0d3c9b',
     dataSource:   [0, 6, 4, 1, 3, 2, 5],
     rangeBandSettings: [
             {
                 startRange: 1,
                 endRange: 2,
                 color: '#bfd4fc',
                 opacity:0.4
             },
             {
                 startRange: 4,
                 endRange: 5,
                 color: 'red',
                 opacity:0.4
             }
         ]
 });
sparkline.appendTo("#element");
