Hello,

I try to implement a XamDataChart with Stacked100ColumnSeries but it seems these components cannot be databind to a collection in the viewmodel !? No problem with a StaticResource but nothing is displayed with a binding to the viewmodel...

Here is the xaml:

<

ig:XamDataChart Margin="0,10,20,0"
HorizontalZoomable="True"
HorizontalZoombarVisibility="Visible"
Legend="{Binding ElementName=scadaStatusStatisticLegend}" >
<ig:XamDataChart.Axes>
<ig:CategoryXAxis x:Name="scadaStatusStatisticXAxis"
ItemsSource="{Binding ScadaStatusStatisticDataList}"
Label="{}{GroupName}"
Strip="Transparent"
MajorStroke="Transparent" >
<ig:CategoryXAxis.LabelSettings >
<ig:AxisLabelSettings Location="OutsideLeft"
Extent="30" />
</ig:CategoryXAxis.LabelSettings>
</ig:CategoryXAxis>
<ig:NumericYAxis x:Name="scadaStatusStatisticYAxis"
MinimumValue="0">
<ig:NumericYAxis.LabelSettings>
<ig:AxisLabelSettings Location="OutsideLeft"
Extent="50" />
</ig:NumericYAxis.LabelSettings>
</ig:NumericYAxis>
</ig:XamDataChart.Axes>
<ig:XamDataChart.Series>
<ig:Stacked100ColumnSeries ItemsSource="{Binding ScadaStatusStatisticDataList}"
XAxis="{Binding ElementName=scadaStatusStatisticXAxis}"
YAxis="{Binding ElementName=scadaStatusStatisticYAxis}" >
<ig:StackedColumnSeries.Series>
<ig:StackedFragmentSeries ValueMemberPath="Status1"
Title="Operation" />
<ig:StackedFragmentSeries ValueMemberPath="Status2"
Title="Technical Problems" />
<ig:StackedFragmentSeries ValueMemberPath="Status3"
Title="Maintenance" />
</ig:StackedColumnSeries.Series>
</ig:Stacked100ColumnSeries>
</ig:XamDataChart.Series>
</ig:XamDataChart>
<ig:Legend x:Name="scadaStatusStatisticLegend"
Grid.Column="0"
Content="{x:Static res:Labels._LegendTitle}"
ig:XamDock.Edge="OutsideRight"
ig:XamDock.VerticalDockAlignment="Center"
ig:XamDock.HorizontalDockAlignment="Right"
Margin="-5,0,5,0"/>

Here is the viewmodel:

Public

Sub New()
Dim statisticDataList = New ObservableCollection(Of StatisticData)
statisticDataList.Add(New StatisticData("01/2010", 80, 10, 5))
statisticDataList.Add(New StatisticData("02/2010", 10, 20, 2))
ScadaStatusStatisticDataList = statisticDataList
End Sub

_scadaStatusStatisticDataList As ObservableCollection(Of StatisticData)
Public Property ScadaStatusStatisticDataList() As ObservableCollection(Of StatisticData)
Get
Return _scadaStatusStatisticDataList
End Get
Set(ByVal value As ObservableCollection(Of StatisticData))
_scadaStatusStatisticDataList = value
OnPropertyChanged(ScalarProperty.ScadaStatusStatisticDataList.ToString())
End Set
End Property

And the data class:

Public

Class StatisticData
Public Property GroupName As String
Public Property Status1 As Double
Public Property Status2 As Double
Public Property Status3 As Double
Public Sub New(ByVal groupName As String, ByVal status1 As Double, ByVal status2 As Double, ByVal status3 As Double)
Me.GroupName = groupName
Me.Status1 = status1
Me.Status2 = status2
Me.Status3 = status3
End Sub
End Class

Thanks for your help,
