Binding line series to Array/List

[Andrey]

Hi, 
I have my model described like: 
    public class PerformanceChartSeriesModel_2
    {
        public string[] Date { get; set; }
        public double[] P1 { get; set; }
    }

Now, I chart :
    @(Html.Kendo().Chart<PerformanceChartSeriesModel_2>()
        .Name("chartPerformance")        
        .Legend(legend => legend
        .Position(ChartLegendPosition.Bottom)
        )
        .DataSource(ds => ds
            .Read(read => read.Action("PerformanceChartData", "Performance").Data("performanceChartData"))
        )
       .Series(series =>
       {
           series.Line(p=>p.P1);                      
       })
               .CategoryAxis(axis =>
               {
                   axis.Categories(l => l.Date);
               })   

Neither series nor categories pick up values, series actually behave in a strange way drawing only one point.
Could you tell what is wrong, or how can I work with such model.
Thanks.

Hello Andrey Dorokhov,

As you can see in our offline example line-charts/remote-data you need to pass an array with objects. Then you need to specify the bindable field.

If you want to pass an array to the series you can do this with ViewBag or Model.Something.

Kind regards,

Hi!

Can you show me the PerformanceChartData action of your Performance controller? I'm facing similar problem and try to find some solution... My action returns with Json(res.ToDataSourceResult(request)), where res is IEnumerable<MyClass>.

 

Many thanks

Hello, Attila,

In general, the Action should return an array of objects as Hristo suggested.

Please inspect the response from the server when the data is returned with "Json(res.ToDataSourceResult(request))"

The expected result can be observed in our demo:

Please have in mind that this is an old thread and there is a big chance Andrey to not have the code available as this was 5 years ago.

If there is a specific issue, please provide more details or runnable example and we will gladly assist.

Regards,
Stefan
