Hi,

   I am using XamChart with 2 series one Line and other Area. 

<igChart:XamChart.Series>

<igChart:Series ChartType="Area" DataMapping="Value = ActiveNode; Label = TimeStamp"

DataSource="{Binding Path=ChartPointCollection, Mode=OneWay}" Stroke="GreenYellow"

Fill="GreenYellow" StrokeThickness="4" Label="Active Node"/> 

<igChart:Series ChartType="Line" DataMapping="Value = AvailableNode; Label = TimeStamp; ToolTip=AvailableNode" DataSource="{Binding Path=ChartPointCollection, Mode=OneWay}"

StrokeThickness="2" Fill="DarkRed" Stroke="DarkRed" Label="Available Node"/> 

</igChart:XamChart.Series>

Both series are bind to a ObservableCollection. Everything works fine and I am getting both Line and Area graph but also getting a Binding Error message with every point added to collection

System.Windows.Data Error: 39 : BindingExpression path error: 'AreaPoint1' property not found on 'object' ''AreaChartTemplate' (HashCode=4892154)'. BindingExpression:Path=AreaPoint1; DataItem='AreaChartTemplate' (HashCode=4892154); target element is 'PathFigure' (HashCode=44029393); target property is 'StartPoint' (type 'Point')

 How to get rid of this error message?

Thanks,

Deep
