Selection in ASP.NET MVC 3D Chart Component

9 Jan 202419 minutes to read

The 3D chart provides selection support for the series and its data points on mouse click.

When mouse is clicked on the data points, the corresponding series legend will also be selected.

We have different types of selection mode for selecting a data.

• None
• Point
• Series
• Cluster

Point

To select a point, set the SelectionMode property to Point.

Selection type

To select multiple points or series, enable the IsMultiSelect property.

CSHTML

@(Html.EJS().Chart3D("container").WallColor("transparent").EnableRotation(true).Rotation(7).Tilt(10).Depth(100)
   .Series(series =>
   {
      series.Type(Syncfusion.EJ2.Charts.Chart3DSeriesType.Column).  
      XName("country").
      YName("gold").
      Name("Gold").
      DataSource(ViewBag.dataSource).
      Add();

      series.Type(Syncfusion.EJ2.Charts.Chart3DSeriesType.Column).  
      XName("country").
      YName("silver").
      Name("Silver").
      DataSource(ViewBag.dataSource).
      Add();

      series.Type(Syncfusion.EJ2.Charts.Chart3DSeriesType.Column).  
      XName("country").
      YName("bronze").
      Name("Bronze").
      DataSource(ViewBag.dataSource).
      Add();
   })
   .PrimaryXAxis(px => 
      px.ValueType(Syncfusion.EJ2.Charts.ValueType.Category)
   )
   .Title("Olympic Medals")
   .SelectionMode(Syncfusion.EJ2.Charts.Chart3DSelectionMode.Series)
   .IsMultiSelect(true)
   .Render())

Selection-type.cs

public ActionResult Index()
{
    List<ChartData> chartData = new List<ChartData>
    {
        new ChartData { country= "USA",       gold= 50, silver= 70, bronze= 45 },
        new ChartData { country= "China",     gold= 40, silver= 60, bronze= 55 },

    public string country;
    public double gold;
    public double silver;
    public double bronze;

Selection during initial loading

In a 3D chart, selecting a point or series during initial loading can only be done programmatically. The SelectedDataIndexes property can be used for this.

CSHTML

@(Html.EJS().Chart3D("container").WallColor("transparent").EnableRotation(true).Rotation(7).Tilt(10).Depth(100)
   .Series(series =>
   {
      series.Type(Syncfusion.EJ2.Charts.Chart3DSeriesType.Column).  
      XName("country").
      YName("gold").
      Name("Gold").
      DataSource(ViewBag.dataSource).
      Add();

      series.Type(Syncfusion.EJ2.Charts.Chart3DSeriesType.Column).  
      XName("country").
      YName("silver").
      Name("Silver").
      DataSource(ViewBag.dataSource).
      Add();

      series.Type(Syncfusion.EJ2.Charts.Chart3DSeriesType.Column).  
      XName("country").
      YName("bronze").
      Name("Bronze").
      DataSource(ViewBag.dataSource).
      Add();
   })
   .PrimaryXAxis(px => 
      px.ValueType(Syncfusion.EJ2.Charts.ValueType.Category)
   )
   .Title("Olympic Medals")
   .SelectionMode(Syncfusion.EJ2.Charts.Chart3DSelectionMode.Point)
   .IsMultiSelect(true)
   .SelectedDataIndexes(ViewBag.selectedData)
   .Render())

Onload.cs

public ActionResult Index()
{
    List<ChartData> chartData = new List<ChartData>
    {
        new ChartData { country= "USA",       gold= 50, silver= 70, bronze= 45 },
        new ChartData { country= "China",     gold= 40, silver= 60, bronze= 55 },
        new ChartData { country= "Japan",     gold= 70, silver= 60, bronze= 50 },
        new ChartData { country= "Australia", gold= 60, silver= 56, bronze= 40 },
        new ChartData { country= "France",    gold= 50, silver= 45, bronze= 35 },
        new ChartData { country= "Germany",   gold= 40, silver= 30, bronze= 22 },
        new ChartData { country= "Italy",     gold= 40, silver= 35, bronze= 37 },
        new ChartData { country= "Sweden",    gold= 30, silver= 25, bronze= 27 }
    };
    ViewBag.dataSource = chartData;
    return View();
}
public class ChartData
{
    public string country;
    public double gold;
    public double silver;
    public double bronze;
}

Selection through legend

To select a point or series through on legend use ToggleVisibility property. Also, use EnableHighlight property for highlighting the series through legend.

CSHTML

@(Html.EJS().Chart3D("container").WallColor("transparent").EnableRotation(true).Rotation(7).Tilt(10).Depth(100)
   .Series(series =>
   {
      series.Type(Syncfusion.EJ2.Charts.Chart3DSeriesType.Column).  
      XName("country").
      YName("gold").
      Name("Gold").
      DataSource(ViewBag.dataSource).
      Add();

      series.Type(Syncfusion.EJ2.Charts.Chart3DSeriesType.Column).  
      XName("country").
      YName("silver").
      Name("Silver").
      DataSource(ViewBag.dataSource).
      Add();

      series.Type(Syncfusion.EJ2.Charts.Chart3DSeriesType.Column).  
      XName("country").
      YName("bronze").
      Name("Bronze").
      DataSource(ViewBag.dataSource).
      Add();
   })
   .PrimaryXAxis(px => 
      px.ValueType(Syncfusion.EJ2.Charts.ValueType.Category)
   )
   .Title("Olympic Medals")
   .LegendSettings(lg => lg.Visible(true).ToggleVisibility(false).EnableHighlight(true))
   .Render())

Selection-legend.cs

public ActionResult Index()

        new ChartData { country= "USA",       gold= 50, silver= 70, bronze= 45 },
        new ChartData { country= "China",     gold= 40, silver= 60, bronze= 55 },
        new ChartData { country= "Japan",     gold= 70, silver= 60, bronze= 50 },
