    [CLOSED] "SeriesLabel" in Line Chart not displaying properly

    Hi,

    I am having a dynamic Line Chart where i am displaying a custom text on Line series marker, Say i want to display "A" or "P" on line series "Diamond" marker. I have achieved this by using "SeriesLabel" option of "LineSeries". I have added the 2 model fields which contain "A" and "P" and assigned it to SeriesLabel based on the condition.

    But the issue i have facing is, Line Chart is displaying either "A" or "P" on marker for the all line series but not both simultaneously.

    Here is the sample snapshot which will give you better idea


    Below it sample code:

    This example contains 2 series one is for Albania and second is for France country, for Albania text "A" should be displayed and for France text "P" should display on line series in Diamond marker, but Line chart is displaying "P" for both the series.

    //Controller & Model

    
      public class GrpColumns
            {
                public string Country { get; set; }
                public string IsScheduled { get; set; }
                public bool? isProvisional { get; set; }
                public string MonthName { get; set; }
                public double Value { get; set; }
            }
    
            public ActionResult Index()

            layout: "fit"

    });
    As far as you can see both the Series are rendered with the same label configuration including the "field" which a label's text comes from.
    label: {
        "stroke": "#fdfdf9",
        "stroke-width": 0.0,
        "zIndex": 100000,
        "display": "middle",
        "color": "#fdfdf9",
        "field": "SeriesLabelFrance"
    }
    I guess there is a logical error in the C# code. Please investigate.
  3. #3
    Sorry for late reply.

    Yes, in sample example which i posted there was issue sorry for that, but in real application there was no logical error.

    Anyway by changing the approach problem has been solved.

    Thanks..
