Binding issue with Spline Series in XAML
posted

Hi,

I am using a xamDataChart and a SplineSeries. But unfortunately I am not able to bind my data with that.
Could you please see whether it will work with code which I have written?

Thanks

<Style TargetType="{x:Type ig:SplineSeries}" BasedOn="{StaticResource {x:Type ig:SplineSeries}}">
<Setter Property="ItemsSource" Value="{Binding Items}"/>
<Setter Property="ValueMemberPath" Value="SCurveValue" />
<Setter Property="XAxis" Value="{Binding ElementName=XAxis}"/>
<Setter Property="YAxis" Value="{Binding ElementName=YAxis}"/>
</Style>

 <ig:NumericYAxis x:Name="YAxis" MinimumValue="21" MaximumValue="29" ></ig:NumericYAxis>

<Style x:Name="XAxis" TargetType="{x:Type ig:CategoryXAxis}" BasedOn="{StaticResource {x:Type ig:CategoryXAxis}}">
<Setter Property="ItemsSource" Value="{Binding Path=AllSeries[0].Items, Mode=OneWay}" />
<Setter Property="Label" Value="{}" />
</Style>

    Hi,

    Thank you for posting in our forums.

    When setting up SplineSeries for a Resources, you should add the same XAxis and YAxis to the XamDataChard.Axis property.

    ------------------------------------------------------------------------------
    <Style TargetType="{x:Type ig:XamDataChart}">
    <Style.Resources>

    <ig:CategoryXAxis x:Key="XAxis" ItemsSource="{Binding Items}" Label="{}{Year}" />
    <ig:NumericYAxis x:Key="YAxis" />

    <Style TargetType="{x:Type ig:SplineSeries}">
    <Setter Property="ItemsSource" Value="{Binding Items}"/>
    <Setter Property="ValueMemberPath" Value="SCurveValue" />
    <Setter Property="XAxis" Value="{StaticResource XAxis}"/>
    <Setter Property="YAxis" Value="{StaticResource YAxis}"/>
    </Style>
    </Style.Resources>

    <Setter Property="local:AxesService.XAxis" Value="{StaticResource XAxis}" />
    <Setter Property="local:AxesService.YAxis" Value="{StaticResource YAxis}" />
    </Style>


    <ig:XamDataChart x:Name="xamDataChart" >
    <ig:XamDataChart.Series>
    <ig:SplineSeries x:Name="splineSeries" ></ig:SplineSeries>
    </ig:XamDataChart.Series>
    <ig:XamDataChart.Axes>
    </ig:XamDataChart.Axes>
    </ig:XamDataChart>
    ------------------------------------------------------------------------------

    I created a sample app.
    Please check an attached file.
