Data binding question for SfChart

How to use the TimeSpanAxis for a Series where bound collection x axis property is of type double representing seconds?  Is there a way to use a converter with the XBindingPath? I am assuming if using the TimeSpanAxis for the Primary, that the type expected for the Series XBindingPath needs to be a TimeSpan or a string with a valid time span representation?

Hi Jack,

We have validated your query and would like to suggest that you can use your double type seconds data in our TimeSpan axis by using below solution. 

You can convert your seconds to TimeSpan by using TimeSpan.FromSeconds methods. Then assign the TimeSpan type model property to our XBindingPath as per the below code snippet. 

public class ViewModel


        private Random random;

        public ObservableCollection<ChartModel> Data { get; set; }

        public ViewModel()


            random = new Random();

            Data = new ObservableCollection<ChartModel>();

            for(int i=0; i<10;i++)


                Data.Add(new ChartModel() { TimeSpanValue = GetTimeSpanValue(random.Next(20,120)),

                                           Value1 = random.Next(10,50) });



        private TimeSpan GetTimeSpanValue(double seconds)


            return TimeSpan.FromSeconds(seconds);



public class ChartModel


        public double Value1 { get; set; }

        public TimeSpan TimeSpanValue { get; set; }












            <chart:LineSeries ItemsSource="{Binding Data}" Label="First"

                                           XBindingPath="TimeSpanValue" YBindingPath="Value1" />



I have also attached a demo sample based on your requirement, please check and let us know if need any further assistance.
