        minorTickLines: {width: 4, color: 'red'},
        dataSource: [{ value: 23, target: 22 }],
        animation: { enable: false },
        valueField: 'value',
        targetField: 'target',
        ranges: [{ end: 20 },
            { end: 25 },
            { end: 30 }

Category Label

The Bullet Chart supports X-axis label by specifying the property from the data source to the categoryField. It helps to understand the input data in a more efficient way.

var chart = new ej.charts.BulletChart({
      title: 'Sales Rate',
        dataSource: [{ value: 1500, target: 1300, category: 'Product A'  }],
        animation: { enable: false },
        valueField: 'value',
        targetField: 'target',
        categoryField: 'category',
        ranges: [{ end: 500 },
            { end: 1500 },
            { end: 2500 }
        ],
        minimum: 0, maximum: 2500, interval: 250

Category Label Customization

The label color, opacity, font size, font family, font weight, and font style can be customized by using the categoryLabelStyle setting for category and the labelStyle setting for axis label. The useRangeColor property specifies the color of the axis label and represents the color from the corresponding range colors.

var chart = new ej.charts.BulletChart({
      title: 'Sales Rate',
        dataSource: [{ value: 1500, target: 1300, category: 'Product A'  }],
        animation: { enable: false },
        valueField: 'value',
        targetField: 'target',
