Its back up. So you can check that out if you want. But the exampl linked is really more for if you want to create the series based on a template in Xaml. If you are already creating the series collection in your View Model have you tried just binding it to the chart?

I.E if the property holding the SeriesCollection on your DataContext is called Series. Have you tried

<XamWebChart Series="{Binding Series} ...

Thank you very much Graham. That works like a charm. If possible, please keep me posted about the bug status.

Thank you.

Hi,

I'm trying to do the same thing for a XamDataChart, but the Series property is marked as read-only. How would one assign the series collection to the control fro mthe view model in this control?

Sorry for the delay, I've been out of the office for a while. Here's something that can should get you started.
The gist is to use an attached property to synchronize your source viewmodel with the series that are populated in the chart.
The viewmodels for the series are produce the concrete series by means of a DataTemplate you provide which should produce a series when loaded.

Here's an example of the Xaml:

<Grid x:Name="LayoutRoot" Background="White">
        <Grid.RowDefinitions>
            <RowDefinition />
            <RowDefinition Height="Auto"/>
        </Grid.RowDefinitions>
        <ig:XamDataChart Name="xamDataChart1" >
            <ig:XamDataChart.Axes>
                <ig:CategoryXAxis x:Name="xAxis"
                          ItemsSource="{Binding Item.Data}"
                          Label="{}{Label}"/>
                <ig:NumericYAxis x:Name="yAxis" />
            </ig:XamDataChart.Axes>
            
            <local:SeriesBinder.BindingInfo>
                <local:SeriesBindingInfo 
                    ItemsSource="{Binding}">
                    <local:SeriesBindingInfo.SeriesTemplate>
                        <DataTemplate>
                            <ig:LineSeries 
                                ItemsSource="{Binding Item.Data}"
                                ValueMemberPath="{Binding Item.ValueMemberPath}"
                                XAxis="{Binding Path=Owner.Axes[0]}"
                                YAxis="{Binding Path=Owner.Axes[1]}"
                                >
                            </ig:LineSeries>
                        </DataTemplate>
                    </local:SeriesBindingInfo.SeriesTemplate>
                </local:SeriesBindingInfo>
            </local:SeriesBinder.BindingInfo>
        </ig:XamDataChart>

        <Button Grid.Row="1" 
                Content="Click" 
                Click="Button_Click"/>
    </Grid>

And here is the code behind to support this usage:

        public MainPage()

            InitializeComponent();

            DataContext = new TestSeries();
        }

        {

    }

                                    .OuterContext = GetContextBridge(o);
                            }
                        }
                    }
                }));


        public static void SetBindingInfo(
            DependencyObject target,
            SeriesBindingInfo info)
        {
            target.SetValue(BindingInfoProperty, info);
        }

        public static SeriesBindingInfo GetBindingInfo(
            DependencyObject target)
        {
            return (SeriesBindingInfo)target.GetValue(BindingInfoProperty);
        }

        public static void SetContextBridge(
            DependencyObject target,
            object context)
        {
            target.SetValue(ContextBridgeProperty, context);
        }

        public static object GetContextBridge(

    }

The above example was assuming a situation where you wanted to share axes between all the series in the chart
However, you could also use an approach like this to define seperate axes per item in your viewmodel collection, e.g:

<Grid x:Name="LayoutRoot" Background="White">
        <Grid.RowDefinitions>
            <RowDefinition />
            <RowDefinition Height="Auto"/>
        </Grid.RowDefinitions>
        <ig:XamDataChart Name="xamDataChart1" >
            <ig:XamDataChart.Axes>
                <ig:NumericYAxis x:Name="yAxis" />
            </ig:XamDataChart.Axes>
            
            <local:SeriesBinder.BindingInfo>
                <local:SeriesBindingInfo 
                    ItemsSource="{Binding}">
                    <local:SeriesBindingInfo.SeriesTemplate>
                        <DataTemplate>
                            <ig:LineSeries 
                                ItemsSource="{Binding Item.Data}"
                                ValueMemberPath="{Binding Item.ValueMemberPath}"
                                YAxis="{Binding Path=Owner.Axes[0]}"
                                >
                                <ig:LineSeries.XAxis>
                                    <ig:CategoryXAxis
                                        ItemsSource="{Binding Item.Data}"
                                        Label="{}{Label}"/>
                                </ig:LineSeries.XAxis>
                            </ig:LineSeries>
                        </DataTemplate>
                    </local:SeriesBindingInfo.SeriesTemplate>
                </local:SeriesBindingInfo>
            </local:SeriesBinder.BindingInfo>
        </ig:XamDataChart>

        <Button Grid.Row="1" 
                Content="Click" 
                Click="Button_Click"/>
    </Grid>

Hope this helps! Let me know if you have questions.

Dear Graham,

how can i redo this but for stacked column series, its really urgent.

Thanks

For xamWebChart or for xamDataChart? Could you describe what your data looks like?

Hi Graham,

I am facing the same issue with xamGrid - Silverlight. From the description you gave in the post above, it make sense that ICustomTypeProvider works at silverlight binding level but xamGrid works at a level lower than that.

The workaround you suggested of creating runtime types works fine but causes performance overhead. I would ideally like to see ICustomTypeProvider or DynamicObjects binding seamlessly with Infragistics components.

Is there any plan to support this in upcoming Infragistics releases ? I have tried Infragistics 12.1 as well, but its still not implemented.

thx alot

Is there any  article or blog that binds the pivot grid with the datachart??

am searching but there is only for webchart

I believe you can just set the Brush property on each fragment.

OK, i will now try to work with the pivotgrid and bind it :)

but i want to ask a question first,

can i chose the colors of the stacked fragments, because i don't want the randomely selected colors i get

i want to specify the color of the fragment when adding it, can i??
