Column

To render a column series in your chart, you need to follow a few steps to configure it correctly. Here’s a concise guide on how to do this:

  • Set the series type: Define the series Type as Column in your chart configuration. This indicates that the data should be represented as a column chart, which is ideal for visualizing for comparing different categories of data or tracking changes over time.
@Html.EJS().Chart("container").Series(series =>
   {
      series.Type(Syncfusion.EJ2.Charts.ChartSeriesType.Column).  
      XName("x").
      YName("y").
      DataSource(ViewBag.dataSource).
      Name("Gold").
      Add();
   })
   .PrimaryXAxis(px => 
      px.Interval(1)
         .ValueType(Syncfusion.EJ2.Charts.ValueType.Category)
         .IsIndexed(true)
   )
   .Title("Olympic Medal Counts - RIO").Render()
public ActionResult Index()
        {
            List<AxisLabelData> chartData = new List<AxisLabelData>
            {
                new AxisLabelData { x= "South Korea", y= 39.4 },
                new AxisLabelData { x= "India", y= 61.3 }, 
                new AxisLabelData { x= "Pakistan", y= 20.4 },
                new AxisLabelData { x= "Germany", y= 65.1 }, 
                new AxisLabelData { x= "Australia", y= 15.8 },
                new AxisLabelData { x= "Italy", y= 29.2 },
                new AxisLabelData { x= "United Kingdom", y= 44.6 },
                new AxisLabelData { x= "Saudi Arabia", y= 9.7 },
                new AxisLabelData { x= "Russia", y= 40.8 },
                new AxisLabelData { x= "Mexico", y= 31 },
                new AxisLabelData { x= "Brazil", y= 75.9 },
                new AxisLabelData { x= "China", y= 51.4 }
            };
            ViewBag.dataSource = chartData;
            return View();
        }
        public class AxisLabelData
        {
            public string x;
            public double y;
        }

Binding data with series

You can bind data to the chart using the DataSource property within the series configuration. This allows you to connect a JSON dataset or remote data to your chart. To display the data correctly, map the fields from the data to the chart series XName and YName properties.

@Html.EJS().Chart("container").Series(series =>
   {
      series.Type(Syncfusion.EJ2.Charts.ChartSeriesType.Column).  
      XName("x").
      YName("y").
      DataSource(ViewBag.dataSource).
      Name("Gold").
      Add();
   })
   .PrimaryXAxis(px => 
      px.Interval(1)
         .ValueType(Syncfusion.EJ2.Charts.ValueType.Category)
         .IsIndexed(true)
   )
   .Title("Olympic Medal Counts - RIO").Render()
public ActionResult Index()
        {
            List<AxisLabelData> chartData = new List<AxisLabelData>
            {
                new AxisLabelData { x= "South Korea", y= 39.4 },
                new AxisLabelData { x= "India", y= 61.3 }, 
                new AxisLabelData { x= "Pakistan", y= 20.4 },
                new AxisLabelData { x= "Germany", y= 65.1 }, 
                new AxisLabelData { x= "Australia", y= 15.8 },
                new AxisLabelData { x= "Italy", y= 29.2 },
                new AxisLabelData { x= "United Kingdom", y= 44.6 },
                new AxisLabelData { x= "Saudi Arabia", y= 9.7 },
                new AxisLabelData { x= "Russia", y= 40.8 },
                new AxisLabelData { x= "Mexico", y= 31 },
                new AxisLabelData { x= "Brazil", y= 75.9 },
                new AxisLabelData { x= "China", y= 51.4 }
            };
            ViewBag.dataSource = chartData;
            return View();
        }
        public class AxisLabelData
        {
            public string x;
            public double y;
        }

Series customization

The following properties can be used to customize the column series.

Fill

The Fill property determines the color applied to the series.

@Html.EJS().Chart("container").Series(series =>
   {
      series.Type(Syncfusion.EJ2.Charts.ChartSeriesType.Column).
      XName("x").
      YName("y").
      DataSource(ViewBag.dataSource).
      Name("Gold").Fill("blue").
      Add();
   }).PrimaryXAxis(px =>
      px.Interval(1)
         .ValueType(Syncfusion.EJ2.Charts.ValueType.Category)
         .IsIndexed(true)
   ).Title("Olympic Medal Counts - RIO").Render()
public ActionResult Index()
        {
            List<AxisLabelData> chartData = new List<AxisLabelData>
            {
                new AxisLabelData { x= "South Korea", y= 39.4 },
                new AxisLabelData { x= "India", y= 61.3 }, 
                new AxisLabelData { x= "Pakistan", y= 20.4 },
                new AxisLabelData { x= "Germany", y= 65.1 }, 
                new AxisLabelData { x= "Australia", y= 15.8 },
                new AxisLabelData { x= "Italy", y= 29.2 },
                new AxisLabelData { x= "United Kingdom", y= 44.6 },
                new AxisLabelData { x= "Saudi Arabia", y= 9.7 },
                new AxisLabelData { x= "Russia", y= 40.8 },
                new AxisLabelData { x= "Mexico", y= 31 },
                new AxisLabelData { x= "Brazil", y= 75.9 },
                new AxisLabelData { x= "China", y= 51.4 }
            };
            ViewBag.dataSource = chartData;
            return View();
        }
        public class AxisLabelData
        {
            public string x;
            public double y;
        }

The Fill property can be used to apply a gradient color to the column series. By configuring this property with gradient values, you can create a visually appealing effect in which the color transitions smoothly from one shade to another.

<svg style="width:1px; height:1px">
    <defs>
        <linearGradient id="gradient">
            <stop offset="0%" style="stop-color:blue;stop-opacity:5" />
            <stop offset="50%" style="stop-color:violet;stop-opacity:5" />
        </linearGradient>
    </defs>
</svg>

@Html.EJS().Chart("container").Series(series =>
   {
      series.Type(Syncfusion.EJ2.Charts.ChartSeriesType.Column).
      XName("x").
      YName("y").
      DataSource(ViewBag.dataSource).
      Name("Gold").Fill("url(#gradient)").
      Add();
   }).PrimaryXAxis(px =>
      px.Interval(1)
         .ValueType(Syncfusion.EJ2.Charts.ValueType.Category)
         .IsIndexed(true)
   ).Title("Olympic Medal Counts - RIO").Render()
public ActionResult Index()
        {
            List<AxisLabelData> chartData = new List<AxisLabelData>
            {
                new AxisLabelData { x= "South Korea", y= 39.4 },
                new AxisLabelData { x= "India", y= 61.3 }, 
                new AxisLabelData { x= "Pakistan", y= 20.4 },
                new AxisLabelData { x= "Germany", y= 65.1 }, 
                new AxisLabelData { x= "Australia", y= 15.8 },
                new AxisLabelData { x= "Italy", y= 29.2 },
                new AxisLabelData { x= "United Kingdom", y= 44.6 },
                new AxisLabelData { x= "Saudi Arabia", y= 9.7 },
                new AxisLabelData { x= "Russia", y= 40.8 },
                new AxisLabelData { x= "Mexico", y= 31 },
                new AxisLabelData { x= "Brazil", y= 75.9 },
                new AxisLabelData { x= "China", y= 51.4 }
            };
            ViewBag.dataSource = chartData;
            return View();
        }
        public class AxisLabelData
        {
            public string x;
            public double y;
        }

Opacity

The Opacity property specifies the transparency level of the fill. Adjusting this property allows you to control how opaque or transparent the fill color of the series appears.

@Html.EJS().Chart("container").Series(series =>
   {
      series.Type(Syncfusion.EJ2.Charts.ChartSeriesType.Column).  
      XName("x").
      YName("y").
      DataSource(ViewBag.dataSource).
      Name("Gold").
      Opacity(0.5).
      Add();
   }).PrimaryXAxis(px => 
      px.Interval(1)
         .ValueType(Syncfusion.EJ2.Charts.ValueType.Category)
         .IsIndexed(true)
   ).Title("Olympic Medal Counts - RIO").Render()
public ActionResult Index()
        {
            List<AxisLabelData> chartData = new List<AxisLabelData>
            {
                new AxisLabelData { x= "South Korea", y= 39.4 },
                new AxisLabelData { x= "India", y= 61.3 }, 
                new AxisLabelData { x= "Pakistan", y= 20.4 },
                new AxisLabelData { x= "Germany", y= 65.1 }, 
                new AxisLabelData { x= "Australia", y= 15.8 },
                new AxisLabelData { x= "Italy", y= 29.2 },
                new AxisLabelData { x= "United Kingdom", y= 44.6 },
                new AxisLabelData { x= "Saudi Arabia", y= 9.7 },
                new AxisLabelData { x= "Russia", y= 40.8 },
                new AxisLabelData { x= "Mexico", y= 31 },
                new AxisLabelData { x= "Brazil", y= 75.9 },
                new AxisLabelData { x= "China", y= 51.4 }
            };
            ViewBag.dataSource = chartData;
            return View();
        }
        public class AxisLabelData
        {
            public string x;
            public double y;
        }

Dash array

The DashArray property determines the pattern of dashes and gaps in the series.

@Html.EJS().Chart("container").Series(series =>
   {
      series.Type(Syncfusion.EJ2.Charts.ChartSeriesType.Column).
      XName("x").
      YName("y").
      DataSource(ViewBag.dataSource).
      Border(ViewBag.border).
      DashArray("5,5").
      Add();
   }).PrimaryXAxis(px =>
      px.Interval(1)
         .ValueType(Syncfusion.EJ2.Charts.ValueType.Category)
   ).Render()
public ActionResult Index()
        {
            List<AxisLabelData> chartData = new List<AxisLabelData>
            {
                new AxisLabelData { x= "South Korea", y= 39.4 },
                new AxisLabelData { x= "India", y= 61.3 }, 
                new AxisLabelData { x= "Pakistan", y= 20.4 },
                new AxisLabelData { x= "Germany", y= 65.1 }, 
                new AxisLabelData { x= "Australia", y= 15.8 },
                new AxisLabelData { x= "Italy", y= 29.2 },
                new AxisLabelData { x= "United Kingdom", y= 44.6 },
                new AxisLabelData { x= "Saudi Arabia", y= 9.7 },
                new AxisLabelData { x= "Russia", y= 40.8 },
                new AxisLabelData { x= "Mexico", y= 31 },
                new AxisLabelData { x= "Brazil", y= 75.9 },
                new AxisLabelData { x= "China", y= 51.4 }
            };
            ViewBag.dataSource = chartData;
            ChartBorder border = new ChartBorder();
            border.Width = 2;
            border.Color = "#FFA500";
            ViewBag.border = border;
            return View();
        }
        public class AxisLabelData
        {
            public string x;
            public double y;
        }

Border

Use the Border property to customize the width and color of the series border.

@Html.EJS().Chart("container").Series(series =>
   {
      series.Type(Syncfusion.EJ2.Charts.ChartSeriesType.Column).
      XName("x").
      YName("y").
      DataSource(ViewBag.dataSource).
      Border(ViewBag.border).
      Add();
   }).PrimaryXAxis(px =>
      px.Interval(1)
         .ValueType(Syncfusion.EJ2.Charts.ValueType.Category)
   ).Render()
public ActionResult Index()
        {
            List<AxisLabelData> chartData = new List<AxisLabelData>
            {
                new AxisLabelData { x= "South Korea", y= 39.4 },
                new AxisLabelData { x= "India", y= 61.3 }, 
                new AxisLabelData { x= "Pakistan", y= 20.4 },
                new AxisLabelData { x= "Germany", y= 65.1 }, 
                new AxisLabelData { x= "Australia", y= 15.8 },
                new AxisLabelData { x= "Italy", y= 29.2 },
                new AxisLabelData { x= "United Kingdom", y= 44.6 },
                new AxisLabelData { x= "Saudi Arabia", y= 9.7 },
                new AxisLabelData { x= "Russia", y= 40.8 },
                new AxisLabelData { x= "Mexico", y= 31 },
                new AxisLabelData { x= "Brazil", y= 75.9 },
                new AxisLabelData { x= "China", y= 51.4 }
            };
            ViewBag.dataSource = chartData;
            ChartBorder border = new ChartBorder();
            border.Width = 2;
            border.Color = "#FFA500";
            ViewBag.border = border;
            return View();
        }
        public class AxisLabelData
        {
            public string x;
            public double y;
        }

Column space and width

Column space

Use the ColumnSpacing property in the series to adjust the space between columns.

@Html.EJS().Chart("container").Series(series =>
   {
      series.Type(Syncfusion.EJ2.Charts.ChartSeriesType.Column).  
      XName("x").
      YName("y").
      DataSource(ViewBag.dataSource).
      ColumnSpacing(0.5).
      Add();
   }).PrimaryXAxis(px => px.ValueType(Syncfusion.EJ2.Charts.ValueType.Category)).Render()
public ActionResult Index()
        {
            List<AxisLabelData> chartData = new List<AxisLabelData>
            {
                new AxisLabelData { x= "South Korea", y= 39.4 },
                new AxisLabelData { x= "India", y= 61.3 }, 
                new AxisLabelData { x= "Pakistan", y= 20.4 },
                new AxisLabelData { x= "Germany", y= 65.1 }, 
                new AxisLabelData { x= "Australia", y= 15.8 },
                new AxisLabelData { x= "Italy", y= 29.2 },
                new AxisLabelData { x= "United Kingdom", y= 44.6 },
                new AxisLabelData { x= "Saudi Arabia", y= 9.7 },
                new AxisLabelData { x= "Russia", y= 40.8 },
                new AxisLabelData { x= "Mexico", y= 31 },
                new AxisLabelData { x= "Brazil", y= 75.9 },
                new AxisLabelData { x= "China", y= 51.4 }
            };
            ViewBag.dataSource = chartData;
            return View();
        }
        public class AxisLabelData
        {
            public string x;
            public double y;
        }

Column width

Use the ColumnWidth property in the series to adjust the width of the columns.

@Html.EJS().Chart("container").Series(series =>
   {
      series.Type(Syncfusion.EJ2.Charts.ChartSeriesType.Column).  
      XName("x").
      YName("y").
      DataSource(ViewBag.dataSource).
      ColumnWidth(0.75).
      Add();
   }).PrimaryXAxis(px => px.ValueType(Syncfusion.EJ2.Charts.ValueType.Category)).Render()
public ActionResult Index()
        {
            List<AxisLabelData> chartData = new List<AxisLabelData>
            {
                new AxisLabelData { x= "South Korea", y= 39.4 },
                new AxisLabelData { x= "India", y= 61.3 }, 
                new AxisLabelData { x= "Pakistan", y= 20.4 },
                new AxisLabelData { x= "Germany", y= 65.1 }, 
                new AxisLabelData { x= "Australia", y= 15.8 },
                new AxisLabelData { x= "Italy", y= 29.2 },
                new AxisLabelData { x= "United Kingdom", y= 44.6 },
                new AxisLabelData { x= "Saudi Arabia", y= 9.7 },
                new AxisLabelData { x= "Russia", y= 40.8 },
                new AxisLabelData { x= "Mexico", y= 31 },
                new AxisLabelData { x= "Brazil", y= 75.9 },
                new AxisLabelData { x= "China", y= 51.4 }
            };
            ViewBag.dataSource = chartData;
            return View();
        }
        public class AxisLabelData
        {
            public string x;
            public double y;
        }

Column width in pixel

Use the ColumnWidthInPixel property in the series to define the exact width of the columns in pixels. This property ensures that each column maintains the specified width, providing a uniform appearance throughout the chart.

@Html.EJS().Chart("container").Series(series =>
   {
      series.Type(Syncfusion.EJ2.Charts.ChartSeriesType.Column).  
      XName("x").
      YName("y").
      DataSource(ViewBag.dataSource).
      ColumnWidthInPixel(10).
      Add();
   }).PrimaryXAxis(px => px.ValueType(Syncfusion.EJ2.Charts.ValueType.Category)).Render()
public ActionResult Index()
        {
            List<AxisLabelData> chartData = new List<AxisLabelData>
            {
                new AxisLabelData { x= "South Korea", y= 39.4 },
                new AxisLabelData { x= "India", y= 61.3 }, 
                new AxisLabelData { x= "Pakistan", y= 20.4 },

Cylindrical column chart

To render a cylindrical column chart, set the ColumnFacet property to Cylinder in the chart series. This property transforms the regular columns into cylindrical shapes, enhancing the visual representation of the data.

@(Html.EJS().Chart("container").Series(series =>
   {
      series.Type(Syncfusion.EJ2.Charts.ChartSeriesType.Column).  
      XName("country").
      YName("gold").
      ColumnFacet(Syncfusion.EJ2.Charts.ShapeType.Cylinder).
      DataSource(ViewBag.dataSource).
      TooltipMappingName("tooltipMappingName").
      Add();
   })
   .PrimaryXAxis(px => 
      px.Interval(1)
         .ValueType(Syncfusion.EJ2.Charts.ValueType.Category)
   )
   .PrimaryYAxis(py => 
      py.Title("Medal Count")
         .Interval(10).Minimum(0).Maximum(80)
       )
   .Title("Olympic Gold Medal Counts - RIO")
   .Tooltip(tt => tt.Enable(true).Header("<b>${point.tooltip}</b>").Format("Gold Medal: <b>${point.y}</b>")).Render())
public ActionResult Index()
{
    List<CylindricalChartData> chartData = new List<CylindricalChartData>

        new CylindricalChartData { country= "USA",       gold= 50, tooltipMappingName= "USA"       },
        new CylindricalChartData { country= "Japan",     gold= 70, tooltipMappingName= "Japan"     }, 
        new CylindricalChartData { country= "Australia", gold= 60, tooltipMappingName= "Australia" },
        new CylindricalChartData { country= "France",    gold= 50, tooltipMappingName= "France"    }, 
        new CylindricalChartData { country= "Italy",     gold= 40, tooltipMappingName= "Italy"     },
        new CylindricalChartData { country= "Sweden",    gold= 55, tooltipMappingName= "Sweden"    }

    ViewBag.dataSource = chartData;
    return View();
}
public class CylindricalChartData

      Name("Gold").EmptyPointSettings(ViewBag.emptyPoint).
      Add();
   }).PrimaryXAxis(px =>
      px.Interval(1)
         .ValueType(Syncfusion.EJ2.Charts.ValueType.Category)
         .IsIndexed(true)
   ).Title("Olympic Medal Counts - RIO").Render()

            new AxisLabelData { month = "Dec", sales = 32 },
        };
        ViewBag.dataSource = chartData;
        ChartEmptyPointSettings chartEmptyPointSettings = new ChartEmptyPointSettings();
        chartEmptyPointSettings.Mode = EmptyPointMode.Zero;
        ViewBag.emptyPoint = chartEmptyPointSettings;
