Vertical chart

To draw a chart in a vertical manner, change the orientation of the axis using the isTransposed property, which is supported by all series types.

CSHTML
Vertical.cs
<ejs-chart id="container" isTransposed="true">
        <e-series-collection>
                <e-series dataSource="ViewBag.dataSource" xName="x" yName="y"
                        type="@Syncfusion.EJ2.Charts.ChartSeriesType.Spline">
                        <e-series-marker visible="true"></e-series-marker>
                </e-series>
        </e-series-collection>
</ejs-chart>
public ActionResult Index()
        {
            List<VerticalData> chartData = new List<VerticalData>
            {
               new VerticalData{ x= 2005, y= 28 },
               new VerticalData{ x= 2006, y= 25 },
               new VerticalData{ x= 2007, y= 26 }, 
               new VerticalData{ x= 2008, y= 27 },
               new VerticalData{ x= 2009, y= 32 },
               new VerticalData{ x= 2010, y= 35 }, 
               new VerticalData{ x= 2011, y= 30 }
            };
            ViewBag.dataSource = chartData;
            return View();
        }
        public class VerticalData
        {
            public double 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.

CSHTML
Vertical.cs
<ejs-chart id="container" isTransposed="true">
        <e-series-collection>
                <e-series dataSource="ViewBag.dataSource" xName="x" yName="y"
                        type="@Syncfusion.EJ2.Charts.ChartSeriesType.Spline">
                        <e-series-marker visible="true"></e-series-marker>
                </e-series>
        </e-series-collection>
</ejs-chart>
public ActionResult Index()
        {
            List<VerticalData> chartData = new List<VerticalData>
            {
               new VerticalData{ x= 2005, y= 28 },
               new VerticalData{ x= 2006, y= 25 },
               new VerticalData{ x= 2007, y= 26 }, 
               new VerticalData{ x= 2008, y= 27 },
               new VerticalData{ x= 2009, y= 32 },
               new VerticalData{ x= 2010, y= 35 }, 
               new VerticalData{ x= 2011, y= 30 }
            };
            ViewBag.dataSource = chartData;
            return View();
        }
        public class VerticalData
        {
            public double x;
            public double y;
        }

Empty points

Data points with null or undefined values are considered empty. Empty data points are ignored and not plotted on the chart.

Mode

Use the mode property to define how empty or missing data points are handled in the series. The default mode for empty points is Gap.

CSHTML
Empty.cs
<ejs-chart id="container" isTransposed="true">
        <e-series-collection>
            <e-series dataSource="ViewBag.dataSource" xName="x" yName="y"
                      type="@Syncfusion.EJ2.Charts.ChartSeriesType.Spline">
                <e-series-emptypointSettings mode="Syncfusion.EJ2.Charts.EmptyPointMode.Zero"></e-series-emptypointSettings>
                <e-series-marker visible="true"></e-series-marker>
            </e-series>
        </e-series-collection>
    </ejs-chart>
public ActionResult Index()
        {
            List<VerticalData> chartData = new List<VerticalData>
            {
               new VerticalData{ x= 2005, y= 28 },
               new VerticalData{ x= 2006, y= 25 },
               new VerticalData{ x= 2007, y= null }, 
               new VerticalData{ x= 2008, y= 27 },
               new VerticalData{ x= 2009, y= 32 },
               new VerticalData{ x= 2010, y= null }, 
               new VerticalData{ x= 2011, y= 30 }
            };
            ViewBag.dataSource = chartData;
            return View();
        }
        public class VerticalData
        {
            public double x;
            public double y;
        }

Fill

Use the fill property to customize the fill color of empty points in the series.

CSHTML
Empty-fill.cs
<ejs-chart id="container" isTransposed="true">
        <e-series-collection>
            <e-series dataSource="ViewBag.dataSource" xName="x" yName="y"
                      type="@Syncfusion.EJ2.Charts.ChartSeriesType.Spline">
                <e-series-emptypointSettings mode="Syncfusion.EJ2.Charts.EmptyPointMode.Zero" fill="red"></e-series-emptypointSettings>
                <e-series-marker visible="true"></e-series-marker>
            </e-series>
        </e-series-collection>
    </ejs-chart>
public ActionResult Index()
        {
            List<VerticalData> chartData = new List<VerticalData>
            {
               new VerticalData{ x= 2005, y= 28 },
               new VerticalData{ x= 2006, y= 25 },
               new VerticalData{ x= 2007, y= null }, 
               new VerticalData{ x= 2008, y= 27 },
               new VerticalData{ x= 2009, y= 32 },
               new VerticalData{ x= 2010, y= null }, 
               new VerticalData{ x= 2011, y= 30 }
            };
            ViewBag.dataSource = chartData;
            return View();
        }
        public class VerticalData
        {
            public double x;
            public double y;
        }

Border

Use the border property to customize the width and color of the border for empty points.

CSHTML
Empty-border.cs
<ejs-chart id="container" isTransposed="true">
        <e-series-collection>
            <e-series dataSource="ViewBag.dataSource" xName="x" yName="y"

                    <e-emptypointSettings-border width="2" color="red"></e-emptypointSettings-border>
                </e-series-emptypointSettings>
                <e-series-marker visible="true"></e-series-marker>
            </e-series>
        </e-series-collection>
    </ejs-chart>
public ActionResult Index()
        {
            List<VerticalData> chartData = new List<VerticalData>
            {
               new VerticalData{ x= 2005, y= 28 },
               new VerticalData{ x= 2006, y= 25 },
               new VerticalData{ x= 2007, y= null }, 
               new VerticalData{ x= 2008, y= 27 },
               new VerticalData{ x= 2009, y= 32 },
               new VerticalData{ x= 2010, y= null }, 
               new VerticalData{ x= 2011, y= 30 }
            };
            ViewBag.dataSource = chartData;
            return View();
        }
        public class VerticalData
        {
            public double x;
            public double y;
        }

Events

Series render

The seriesRender event allows you to customize series properties, such as data, fill, and name, before they are rendered on the chart.

CSHTML
Series-render.cs
<ejs-chart id="container" isTransposed="true" seriesRender="changeColor">
        <e-series-collection>
                <e-series dataSource="ViewBag.dataSource" xName="x" yName="y"
                        type="@Syncfusion.EJ2.Charts.ChartSeriesType.Spline">
                        <e-series-marker visible="true"></e-series-marker>
                </e-series>
        </e-series-collection>
</ejs-chart>

<script>
        function changeColor(args) {
            args.fill = '#ff6347';
        }
    </script>
public ActionResult Index()
        {
            List<VerticalData> chartData = new List<VerticalData>

               new VerticalData{ x= 2011, y= 30 }
            };
            ViewBag.dataSource = chartData;
