//datasource for column chart
public ActionResult Index()
        {
            List<ColumnChartData> chartData = new List<ColumnChartData>
            {
                new ColumnChartData { x= "USA", yValue= 46 },
                new ColumnChartData { x= "GBR", yValue= 27 },
                new ColumnChartData { x= "CHN", yValue= 26 },
                new ColumnChartData { x= "UK", yValue= 23 },
                new ColumnChartData { x= "AUS", yValue= 16 },

        {
            public string x;

                new ColumnChartData { x= "USA", yValue= 46 },
                new ColumnChartData { x= "GBR", yValue= 27 },

            ViewBag.dataSource = chartData;
            return View();
        }
        public class ColumnChartData
        {
            public string x;
            public double yValue;
        }

Range

Range of the category axis can be customized using minimum, maximum and interval property of the axis.

public ActionResult Index()
        {
            List<ColumnChartData> chartData = new List<ColumnChartData>
            {
                new ColumnChartData { x= "USA", yValue= 46 },
                new ColumnChartData { x= "GBR", yValue= 27 },
                new ColumnChartData { x= "CHN", yValue= 26 },

                new ColumnChartData { x= "MEX", yValue= 20 },
            };
            ViewBag.dataSource = chartData;
            return View();
        }
        public class ColumnChartData
        {
            public string x;
            public double yValue;
        }

Indexed category axis

Category axis also can be rendered based on the index values of data source. This can be achieved by defining the isIndexed property to true in the axis.

public ActionResult Index()
        {
            List<ColumnChartData> chartData = new List<ColumnChartData>
            {
                new ColumnChartData{ x= "Myanmar", y= 7.3 },
                new ColumnChartData{ x= "India", y= 7.9 },
                new ColumnChartData{ x= "Bangladesh", y= 6.8 },
                new ColumnChartData{ x= "Cambodia", y=7.0 },
                new ColumnChartData{ x= "China", y= 6.9 }
            };
            ViewBag.dataSource = chartData;
            List<ColumnChartData> chartData1 = new List<ColumnChartData>
            {
            new ColumnChartData{ x= "Poland", y=2.7 },
            new ColumnChartData{ x= "Australia", y=2.5 },
            new ColumnChartData{ x= "Singapore", y=2.0 },
            new ColumnChartData{ x= "Canada", y=1.4 },
            new ColumnChartData{ x= "Germany", y=1.8 }
            };
            ViewBag.dataSource1 = chartData1;
            return View();
        }
        public class ColumnChartData
        {
            public string x;
            public double y;
