To display the primary data or the current value of the data being measured known as the Feature Measure that should be encoded as a bar. This is called as the Actual Bar or the Feature Bar in the Bullet Chart, and to display the actual bar the ValueField should be mapped to the appropriate field from the data source.

CSHTML

@Html.EJS().BulletChart("container")
                        .Title("Sales Rate")
                        .ValueField("value")
                        .Ranges(rn =>
                        {
                            rn.End(35).Add();
                            rn.End(50).Add();
                            rn.End(100).Add();
                        })
                        .Minimum(0).Maximum(100).Interval(20)
                        .DataSource(ViewBag.dataSource)
                        .Render()

Value-bar.cs

public IActionResult Index()
        {
            List<DefaultBulletData> bulletData = new List<DefaultBulletData>
            {
                new DefaultBulletData { value = 55, target = 75}     
            };
            ViewBag.dataSource = bulletData;
            return View();
        }
        public class DefaultBulletData
        {           
            public double value;
            public double target;
        }

Types of actual bar

The shape of the actual bar can be customized using the Type property of the Bullet Chart. The actual bar contains Rect and Dot shapes. By default, the actual bar shape is Rect.

        {
            List<DefaultBulletData> bulletData = new List<DefaultBulletData>
            {
                new DefaultBulletData { value = 55, target = 75}     
            };
            ViewBag.dataSource = bulletData;
            return View();
        }
        public class DefaultBulletData
        {

                        .ValueField("value")
                        .ValueBorder(vb =>
                        {
                            vb.Color("red").Width(3).Add();
                        })
                        .Ranges(rn =>
                        {
                            rn.End(35).Add();
                            rn.End(50).Add();
                            rn.End(100).Add();
                        })
                        .Minimum(0).Maximum(100).Interval(20)
                        .DataSource(ViewBag.dataSource)
                        .Render()

Value-border.cs

public IActionResult Index()
        {
            List<DefaultBulletData> bulletData = new List<DefaultBulletData>
            {
                new DefaultBulletData { value = 55, target = 75}     
            };
            ViewBag.dataSource = bulletData;
            return View();
        }
        public class DefaultBulletData
        {           
            public double value;
            public double target;
        }

}

@(Html.EJS().BulletChart("container")
        .Title("Sales Rate")
        .ValueField("value")
        .ValueFill(@color)
        .ValueHeight(15)
        .Ranges(rn =>
        {
            rn.End(35).Add();
            rn.End(50).Add();
            rn.End(100).Add();
        })
        .Minimum(0).Maximum(100).Interval(20)
        .DataSource(ViewBag.dataSource)
        .Render())

Value-fill.cs

public IActionResult Index()
        {
            List<DefaultBulletData> bulletData = new List<DefaultBulletData>
            {
                new DefaultBulletData { value = 55, target = 75 }     
            };
            ViewBag.dataSource = bulletData;
            return View();
        }
        public class DefaultBulletData
        {           
            public double value;
            public double target;
        }
