Bubble

To render a bubble 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 Bubble in your chart configuration. This indicates that the data should be displayed as a bubble series in the chart.
@Html.EJS().Chart("container").Series(series =>
   {
      series.Type(Syncfusion.EJ2.Charts.ChartSeriesType.Bubble).
      XName("x").
      YName("y").
      DataSource(ViewBag.dataSource).
      Name("Gold").
      Size("size").
      Width(2).
      Add();
   }).PrimaryXAxis(px => px.Interval(1).ValueType(Syncfusion.EJ2.Charts.ValueType.Category)).Title("Olympic Medal Counts - RIO").Render()
public ActionResult Index()
        {
            List<BubbleChartData> chartData = new List<BubbleChartData>
            {
                new BubbleChartData { x= 92.2, y= 7.8, size= 1.347, text= "China" },
                new BubbleChartData { x= 74, y= 6.5, size= 1.241, text= "India" },
                new BubbleChartData { x= 90.4, y= 6.0, size= 0.238, text= "Indonesia" },
                new BubbleChartData { x= 99.4, y= 2.2, size= 0.312, text= "US" },
                new BubbleChartData { x= 88.6, y= 1.3, size= 0.197, text= "Brazil" },
                new BubbleChartData { x= 99, y= 0.7, size= 0.0818, text= "Germany" },
                new BubbleChartData { x= 72, y= 2.0, size= 0.0826, text= "Egypt" },
                new BubbleChartData { x= 99.6, y= 3.4, size= 0.143, text= "Russia" },
                new BubbleChartData { x= 99, y= 0.2, size= 0.128, text= "Japan" },
                new BubbleChartData { x= 86.1, y= 4.0, size= 0.115, text= "Mexico" },
                new BubbleChartData { x= 92.6, y= 6.6, size= 0.096, text= "Philippines" },
                new BubbleChartData { x= 61.3, y= 1.45, size= 0.162, text= "Nigeria" },
                new BubbleChartData { x= 82.2, y= 3.97, size= 0.7, text= "Hong Kong" },
                new BubbleChartData { x= 79.2, y= 3.9, size= 0.162, text= "Netherland" },
                new BubbleChartData { x= 72.5, y= 4.5, size= 0.7, text= "Jordan" },
                new BubbleChartData { x= 81, y= 3.5, size= 0.21, text= "Australia" },
                new BubbleChartData { x= 66.8, y= 3.9, size= 0.028, text= "Mongolia" },
                new BubbleChartData { x= 78.4, y= 2.9, size= 0.231, text= "Taiwan" }
            };
            ViewBag.dataSource = chartData;
            return View();
        }
        public class BubbleChartData
        {
            public double x;
            public double y;
            public double size;
            public string text;
        }

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.Bubble).
      XName("x").
      YName("y").
      DataSource(ViewBag.dataSource).
      Name("Gold").
      Size("size").
      Width(2).
      Add();
   }).PrimaryXAxis(px => px.Interval(1).ValueType(Syncfusion.EJ2.Charts.ValueType.Category)).Title("Olympic Medal Counts - RIO").Render()
public ActionResult Index()
        {
            List<BubbleChartData> chartData = new List<BubbleChartData>
            {
                new BubbleChartData { x= 92.2, y= 7.8, size= 1.347, text= "China" },
                new BubbleChartData { x= 74, y= 6.5, size= 1.241, text= "India" },
                new BubbleChartData { x= 90.4, y= 6.0, size= 0.238, text= "Indonesia" },
                new BubbleChartData { x= 99.4, y= 2.2, size= 0.312, text= "US" },
                new BubbleChartData { x= 88.6, y= 1.3, size= 0.197, text= "Brazil" },
                new BubbleChartData { x= 99, y= 0.7, size= 0.0818, text= "Germany" },
                new BubbleChartData { x= 72, y= 2.0, size= 0.0826, text= "Egypt" },
                new BubbleChartData { x= 99.6, y= 3.4, size= 0.143, text= "Russia" },
                new BubbleChartData { x= 99, y= 0.2, size= 0.128, text= "Japan" },
                new BubbleChartData { x= 86.1, y= 4.0, size= 0.115, text= "Mexico" },
                new BubbleChartData { x= 92.6, y= 6.6, size= 0.096, text= "Philippines" },
                new BubbleChartData { x= 61.3, y= 1.45, size= 0.162, text= "Nigeria" },
                new BubbleChartData { x= 82.2, y= 3.97, size= 0.7, text= "Hong Kong" },
                new BubbleChartData { x= 79.2, y= 3.9, size= 0.162, text= "Netherland" },
                new BubbleChartData { x= 72.5, y= 4.5, size= 0.7, text= "Jordan" },
                new BubbleChartData { x= 81, y= 3.5, size= 0.21, text= "Australia" },
                new BubbleChartData { x= 66.8, y= 3.9, size= 0.028, text= "Mongolia" },
                new BubbleChartData { x= 78.4, y= 2.9, size= 0.231, text= "Taiwan" }
            };
            ViewBag.dataSource = chartData;
            return View();
        }
        public class BubbleChartData
        {
            public double x;
            public double y;
            public double size;
            public string text;
        }

Series customization

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

Fill

The Fill property determines the color applied to the series.

@Html.EJS().Chart("container").Series(series =>
   {
      series.Type(Syncfusion.EJ2.Charts.ChartSeriesType.Bubble).
      XName("x").
      YName("y").
      DataSource(ViewBag.dataSource).
      Name("Gold").
      Size("size").
      Fill("blue").
      Width(2).
      Add();
   }).PrimaryXAxis(px => px.Interval(1).ValueType(Syncfusion.EJ2.Charts.ValueType.Category)).Title("Olympic Medal Counts - RIO").Render()
public ActionResult Index()
        {
            List<BubbleChartData> chartData = new List<BubbleChartData>
            {
                new BubbleChartData { x= 92.2, y= 7.8, size= 1.347, text= "China" },
                new BubbleChartData { x= 74, y= 6.5, size= 1.241, text= "India" },
                new BubbleChartData { x= 90.4, y= 6.0, size= 0.238, text= "Indonesia" },
                new BubbleChartData { x= 99.4, y= 2.2, size= 0.312, text= "US" },
                new BubbleChartData { x= 88.6, y= 1.3, size= 0.197, text= "Brazil" },
                new BubbleChartData { x= 99, y= 0.7, size= 0.0818, text= "Germany" },
                new BubbleChartData { x= 72, y= 2.0, size= 0.0826, text= "Egypt" },
                new BubbleChartData { x= 99.6, y= 3.4, size= 0.143, text= "Russia" },
                new BubbleChartData { x= 99, y= 0.2, size= 0.128, text= "Japan" },
                new BubbleChartData { x= 86.1, y= 4.0, size= 0.115, text= "Mexico" },
                new BubbleChartData { x= 92.6, y= 6.6, size= 0.096, text= "Philippines" },
                new BubbleChartData { x= 61.3, y= 1.45, size= 0.162, text= "Nigeria" },
                new BubbleChartData { x= 82.2, y= 3.97, size= 0.7, text= "Hong Kong" },
                new BubbleChartData { x= 79.2, y= 3.9, size= 0.162, text= "Netherland" },
                new BubbleChartData { x= 72.5, y= 4.5, size= 0.7, text= "Jordan" },
                new BubbleChartData { x= 81, y= 3.5, size= 0.21, text= "Australia" },
                new BubbleChartData { x= 66.8, y= 3.9, size= 0.028, text= "Mongolia" },
                new BubbleChartData { x= 78.4, y= 2.9, size= 0.231, text= "Taiwan" }
            };
            ViewBag.dataSource = chartData;
            return View();
        }
        public class BubbleChartData
        {
            public double x;
            public double y;
            public double size;
            public string text;
        }

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.Bubble).
      XName("x").
      YName("y").
      DataSource(ViewBag.dataSource).
      Name("Gold").
      Size("size").
      Opacity(0.5).
      Width(2).
      Add();
   }).PrimaryXAxis(px => px.Interval(1).ValueType(Syncfusion.EJ2.Charts.ValueType.Category)).Title("Olympic Medal Counts - RIO").Render()
public ActionResult Index()
        {
            List<BubbleChartData> chartData = new List<BubbleChartData>
            {
                new BubbleChartData { x= 92.2, y= 7.8, size= 1.347, text= "China" },
                new BubbleChartData { x= 74, y= 6.5, size= 1.241, text= "India" },
                new BubbleChartData { x= 90.4, y= 6.0, size= 0.238, text= "Indonesia" },
                new BubbleChartData { x= 99.4, y= 2.2, size= 0.312, text= "US" },

                new BubbleChartData { x= 72, y= 2.0, size= 0.0826, text= "Egypt" },
                new BubbleChartData { x= 99.6, y= 3.4, size= 0.143, text= "Russia" },
                new BubbleChartData { x= 99, y= 0.2, size= 0.128, text= "Japan" },
                new BubbleChartData { x= 86.1, y= 4.0, size= 0.115, text= "Mexico" },
                new BubbleChartData { x= 92.6, y= 6.6, size= 0.096, text= "Philippines" },
                new BubbleChartData { x= 61.3, y= 1.45, size= 0.162, text= "Nigeria" },
                new BubbleChartData { x= 82.2, y= 3.97, size= 0.7, text= "Hong Kong" },
                new BubbleChartData { x= 79.2, y= 3.9, size= 0.162, text= "Netherland" },
                new BubbleChartData { x= 72.5, y= 4.5, size= 0.7, text= "Jordan" },
                new BubbleChartData { x= 81, y= 3.5, size= 0.21, text= "Australia" },
                new BubbleChartData { x= 66.8, y= 3.9, size= 0.028, text= "Mongolia" },
                new BubbleChartData { x= 78.4, y= 2.9, size= 0.231, text= "Taiwan" }
            };
            ViewBag.dataSource = chartData;
            return View();
        }
        public class BubbleChartData
        {
            public double x;
            public double y;
            public double size;
            public string text;
        }

Bubble size mapping

Use the Size property to map the size of each bubble to the value specified in the data source.

@Html.EJS().Chart("container").Series(series =>
   {
      series.Type(Syncfusion.EJ2.Charts.ChartSeriesType.Bubble).
      XName("x").
      YName("y").
      DataSource(ViewBag.dataSource).
      Name("Gold").
      Size("size").
      Width(2).
      Add();
   }).PrimaryXAxis(px => px.Interval(1).ValueType(Syncfusion.EJ2.Charts.ValueType.Category)).Title("Olympic Medal Counts - RIO").Render()
public ActionResult Index()
        {
            List<BubbleChartData> chartData = new List<BubbleChartData>
            {
                new BubbleChartData { x= 92.2, y= 7.8, size= 1.347, text= "China" },
                new BubbleChartData { x= 74, y= 6.5, size= 1.241, text= "India" },
                new BubbleChartData { x= 90.4, y= 6.0, size= 0.238, text= "Indonesia" },
                new BubbleChartData { x= 99.4, y= 2.2, size= 0.312, text= "US" },
                new BubbleChartData { x= 88.6, y= 1.3, size= 0.197, text= "Brazil" },
                new BubbleChartData { x= 99, y= 0.7, size= 0.0818, text= "Germany" },
                new BubbleChartData { x= 72, y= 2.0, size= 0.0826, text= "Egypt" },
                new BubbleChartData { x= 99.6, y= 3.4, size= 0.143, text= "Russia" },
                new BubbleChartData { x= 99, y= 0.2, size= 0.128, text= "Japan" },
                new BubbleChartData { x= 86.1, y= 4.0, size= 0.115, text= "Mexico" },
                new BubbleChartData { x= 92.6, y= 6.6, size= 0.096, text= "Philippines" },
                new BubbleChartData { x= 61.3, y= 1.45, size= 0.162, text= "Nigeria" },
                new BubbleChartData { x= 82.2, y= 3.97, size= 0.7, text= "Hong Kong" },
                new BubbleChartData { x= 79.2, y= 3.9, size= 0.162, text= "Netherland" },
                new BubbleChartData { x= 72.5, y= 4.5, size= 0.7, text= "Jordan" },
                new BubbleChartData { x= 81, y= 3.5, size= 0.21, text= "Australia" },
                new BubbleChartData { x= 66.8, y= 3.9, size= 0.028, text= "Mongolia" },
                new BubbleChartData { x= 78.4, y= 2.9, size= 0.231, text= "Taiwan" }
            };
            ViewBag.dataSource = chartData;
            return View();
        }
        public class BubbleChartData
        {
            public double x;
            public double y;
            public double size;
            public string text;
        }

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.

@Html.EJS().Chart("container").Series(series =>
{
    series.Type(Syncfusion.EJ2.Charts.ChartSeriesType.Bubble).
    XName("x").
    YName("y").
    EmptyPointSettings(empty => empty.Mode(Syncfusion.EJ2.Charts.EmptyPointMode.Zero)).
    DataSource(ViewBag.dataSource).
    Name("Gold").
    Size("size").
    Fill("blue").
    Width(2).
    Add();
}).PrimaryXAxis(px => px.Interval(1).ValueType(Syncfusion.EJ2.Charts.ValueType.Category)).Title("Olympic Medal Counts - RIO").Render()
public ActionResult Index()
        {
            List<BubbleChartData> chartData = new List<BubbleChartData>
            {
                new BubbleChartData { x= 92.2, y= 7.8, size= 1.347, text= "China" },
                new BubbleChartData { x= 74, y= 6.5, size= 1.241, text= "India" },
                new BubbleChartData { x= 90.4, y= 6.0, size= 0.238, text= "Indonesia" },
                new BubbleChartData { x= 99.4, y= 2.2, size= 0.312, text= "US" },

                new BubbleChartData { x= 72, y= 2.0, size= 0.0826, text= "Egypt" },
                new BubbleChartData { x= 99.6, y= 3.4, size= 0.143, text= "Russia" },
                new BubbleChartData { x= 99, y= 0.2, size= 0.128, text= "Japan" },
                new BubbleChartData { x= 86.1, y= 4.0, size= 0.115, text= "Mexico" },
                new BubbleChartData { x= 92.6, y= null, size= 0.096, text= "Philippines" },
                new BubbleChartData { x= 61.3, y= 1.45, size= 0.162, text= "Nigeria" },
                new BubbleChartData { x= 82.2, y= 3.97, size= 0.7, text= "Hong Kong" },
                new BubbleChartData { x= 79.2, y= 3.9, size= 0.162, text= "Netherland" },
                new BubbleChartData { x= 72.5, y= 4.5, size= 0.7, text= "Jordan" },
                new BubbleChartData { x= 81, y= 3.5, size= 0.21, text= "Australia" },
                new BubbleChartData { x= 66.8, y= 3.9, size= 0.028, text= "Mongolia" },
                new BubbleChartData { x= 78.4, y= 2.9, size= 0.231, text= "Taiwan" }
            };
            ViewBag.dataSource = chartData;
            return View();
        }
        public class BubbleChartData
        {
            public double x;
            public double? y;
            public double size;
            public string text;
        }

Fill

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

@Html.EJS().Chart("container").Series(series =>
