HI all,

I am new on syncfusion products and I met some trouble with syncfusion chart control.
I am pretty sure it's pretty easy but i don't figure out.

I try to make a column chart with a category primary axis and a timespan secondary axis but I get a InvalidCastException: Unable to cast object of type 'System.TimeSpan' to type 'System.IConvertible'.

Code below :

XAML :

<Grid.DataContext>
       <local:ViewModel/>
</Grid.DataContext>
...
<chart:SfChart x:Name="columnChart" AreaBorderBrush="#8e8e8e" Background="White" Grid.Row="0">
                <chart:SfChart.Header>
                    <TextBlock FontSize="22"   Foreground="Black" FontFamily="Segoe UI">Time spend by application</TextBlock>
                </chart:SfChart.Header>
                <chart:SfChart.PrimaryAxis>
                    <chart:CategoryAxis  Header="Applications" Foreground="Black"  FontSize="20" LabelTemplate="{StaticResource labelTemplate}"/>
                </chart:SfChart.PrimaryAxis>
                <chart:SfChart.SecondaryAxis>
                    <chart:TimeSpanAxis  FontSize="20" Minimum="0" Maximum="500" Interval="50"   Header="Time (in Min)" Foreground="Black" LabelTemplate="{StaticResource labelTemplate}"/>
                </chart:SfChart.SecondaryAxis>
                <chart:ColumnSeries EnableAnimation="True" Palette="Metro" ItemsSource="{Binding ApplicationTime}"  XBindingPath="ApplicationName" YBindingPath="Time" Label="Sneakers sold" chart:ChartTooltip.EnableAnimation="true" ShowTooltip="True"> ...

View Model :

public class ViewModel
    {
        public ObservableCollection<Model> ApplicationTime { get; set; }

        public ViewModel()
        {
            ApplicationTime = new ObservableCollection<Model>();
            ApplicationTime.Add(new Model { ApplicationName = "Visual Studio 2013", Time = new TimeSpan(1,40,30)});
        }
    }

Model :

    public class Model
    {
        public TimeSpan Time { get; set; }
        public string ApplicationName { get; set; }
    }



Maybe I have to herit System.TimeSpan class to implements IConvertible (to convert it to double) ?

Thanks.

Dear Customer,

Thanks for using Syncfusion products.

At present we are not having TimeSpanAxis support for chart secondary axis. However we have meet your requirement in workaround by converting TimeSpan value to double. Please find the sample in the below location.
