Legend in ASP.NET MVC 3D Chart Component

11 Jan 202424 minutes to read

Legend provides information about the series rendered in the 3D chart.

Position and alignment

By using the Position property, the legend can be positioned at left, right, top or bottom of the 3D chart. The legend is positioned at the bottom of the 3D chart, by default.

CSHTML

@(Html.EJS().Chart3D("container").WallColor("transparent").EnableRotation(true).Rotation(7).Tilt(10).Depth(100)
   .Series(series =>

   )
   .Title("Olympic Medals")
   .LegendSettings(lg => lg.Visible(true).Position(Syncfusion.EJ2.Charts.LegendPosition.Top))
   .Render())

Position.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;
}

The custom position helps you to position the legend anywhere in the 3D chart using X and Y coordinates.

}

Legend alignment

The legend can be aligned at near, far or center to the 3D chart using the Alignment property.

Legend customization

To change the legend icon shape, LegendShape property in the Series can be used. By default, the legend icon shape is SeriesType.

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").
      LegendShape(Syncfusion.EJ2.Charts.LegendShape.Circle).
      DataSource(ViewBag.dataSource).
      Add();

      series.Type(Syncfusion.EJ2.Charts.Chart3DSeriesType.Column).

        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 },

    return View();
}
public class ChartData
{
    public string country;
    public double gold;
    public double silver;
    public double bronze;
}

Legend size

By default, legend takes 20% - 25% of the 3D chart’s height horizontally, when it is placed on top or bottom position and 20% - 25% of the 3D chart’s width vertically, when it is placed on left or right position. You can change this default legend size by using the Height and Width properties of the LegendSettings.
