[Solved] Populate data to RadChart 3D Stacked Bar

[Heiko]

Hi,

I am working with RadChart 3D Stacked Bar.

Is it possible to send me an example, how I can populate data , including YValues, XCategories and Legend with more than one SeriesMapping.

Thank you & kind regards,

Heiko

Hello Heiko,
I believe you will find the following online resources helpful, considering the task you have before you:

1. http://demos.telerik.com/silverlight/#Chart/Gallery3D/StackedBar
2. http://www.telerik.com/help/silverlight/radchart-features-categorical-charts.html

Apart from these links, below I have included the code of a simple example, demonstrating the approach that you can use:

<UserControl.DataContext>
    <data:ViewModel></data:ViewModel>
</UserControl.DataContext>

<Grid x:Name="LayoutRoot" Background="White">

    <telerik:RadChart x:Name="radChart" telerik:StyleManager.Theme="Windows7" ItemsSource="{Binding Data}">
        <telerik:RadChart.DefaultView>
            <telerik:ChartDefaultView>
                <telerik:ChartDefaultView.ChartLegend>
                    <telerik:ChartLegend Name="legend" ReverseLegendItemsOrder="True" />
                </telerik:ChartDefaultView.ChartLegend>
                <telerik:ChartDefaultView.ChartArea>
                    <telerik:ChartArea LegendName="legend">
                        <telerik:ChartArea.Extensions>
                            <telerik:CameraExtension />
                        </telerik:ChartArea.Extensions>
                    </telerik:ChartArea>
                </telerik:ChartDefaultView.ChartArea>
            </telerik:ChartDefaultView>
        </telerik:RadChart.DefaultView>
        <telerik:RadChart.SeriesMappings>
            <telerik:SeriesMapping LegendLabel="Stacked Bar 1" CollectionIndex="0">
                <telerik:SeriesMapping.SeriesDefinition>
                    <telerik:StackedBar3DSeriesDefinition StackGroupName="Stack1" />
                </telerik:SeriesMapping.SeriesDefinition>
                <telerik:ItemMapping DataPointMember="YValue" FieldName="Value1" />
                <telerik:ItemMapping DataPointMember="XCategory" FieldName="Category" />
            </telerik:SeriesMapping>
            <telerik:SeriesMapping LegendLabel="Stacked Bar 2" CollectionIndex="1">
                <telerik:SeriesMapping.SeriesDefinition>
                    <telerik:StackedBar3DSeriesDefinition StackGroupName="Stack1" />
                </telerik:SeriesMapping.SeriesDefinition>
                <telerik:ItemMapping DataPointMember="YValue" FieldName="Value2" />
                <telerik:ItemMapping DataPointMember="XCategory" FieldName="Category" />
            </telerik:SeriesMapping>
        </telerik:RadChart.SeriesMappings>
    </telerik:RadChart>
</Grid>

public class ViewModel
{
    public ObservableCollection<ObservableCollection<DemoData>> Data
    {
        get
        {
            ObservableCollection<ObservableCollection<DemoData>> seriesData;
            seriesData = new ObservableCollection<ObservableCollection<DemoData>>()
            {
                new ObservableCollection<DemoData>(){
                    new DemoData() {Category="Category 0", Value1 = 23.4600},
                    new DemoData() { Category="Category 1", Value1 = 23.3200},
                    new DemoData() { Category="Category 2", Value1 = 23.1300},
                    new DemoData() { Category="Category 3", Value1 = 23.6300},
                    new DemoData() { Category="Category 4", Value1 = 23.6200}},
                new ObservableCollection<DemoData>(){
                    new DemoData() {Category="Category 1", Value2 = 10.2},
                    new DemoData() { Category="Category 2", Value2 = 12.6},
                    new DemoData() { Category="Category 3", Value2 = 30.1},
                    new DemoData() { Category="Category 4", Value2 = 5.3},
                    new DemoData() { Category="Category 5", Value2 = 1.5}}
            };
            return seriesData;
        }
    }
}

public class DemoData
{
    public string Category
    {
        get;
        set;
    }
    public double Value1
    {
        get;
        set;
    }
    public double Value2
    {
        get;
        set;
    }
}

All the best,
