pie chart with a list

[Norberto]

Hello

I have a list on my controller

Controller:

var generoEncuestas = (from genero in db.Encuestas

                                      select new { genero.Femenino, genero.Masculino, 

                                                           genero.SinEspecificarGenero }).ToList();

ViewBag.GeneroEncuestas = generoEncuestas;

1. Can the list be graphed?

2. How to graph in the view?

Happy New Year 2018

Hi Norberto, 

 

Thanks for using Syncfusion products.  

 

We have analyzed your query. Your requirement can be achieved by passing the list from controller to view through ViewBag. Now assign the data to the ‘dataSource’ property in series, then map the properties from list to xName and yName properties in series to render the graph . Please find the code snippet and screenshot below 

 

[CSHTML] 

  

@(Html.EJ().Chart("container") 

.Series(sr => 

    {                          sr.DataSource((IEnumerable<object>)ViewBag.dataSource).XName("XValue").YName("YValue").Add(); 

    }) 

) 

  

[CS] 

public ActionResult Pie() 

{ 

List<ChartPieData> data = new List<ChartPieData>(); 

            data.Add(new ChartPieData("Other Personal", 80)); 

            data.Add(new ChartPieData("Medical care", 70)); 

            data.Add(new ChartPieData("Housing", 60)); 

            data.Add(new ChartPieData("Transportation", 50)); 

            data.Add(new ChartPieData("Education", 40)); 

            data.Add(new ChartPieData("Electronics", 30)); 

            ViewBag.dataSource = data; 

            return View(); 

} 

public class ChartPieData 

    { 

        public ChartPieData(string xval, double yval) 

        { 

            this.XValue = xval; 

            this.YValue = yval; 

  

        } 

        public string XValue 

        { 

            get; 

            set; 

        } 

        public double YValue 

        { 

            get; 

            set; 

        } 

    }
