Comparative bar in EJ2 JavaScript Bullet chart control

29 Dec 20238 minutes to read

The line marker that runs perpendicular to the orientation of the graph is known as the Comparative Measure and it is used as a target marker to compare against the feature measure value. This is also called as the Target Bar in the Bullet Chart. To display the target bar, the targetField should be mapped to the appropriate field from the datasource.

var chart = new ej.charts.BulletChart({
        title: 'Sales Rate',
        dataSource: [
        { value: 55, target: 75, category: 'Year 1'  },
        ],
        animation: { enable: false },
        targetField: 'target',
        ranges: [ { end: 35 },
        { end: 50 },
        { end: 100 }
        ],
        minimum: 0, maximum: 100, interval: 20
}, '#element');
