Hi, I am using charts in my app. In certain screens chart works fine but in certain screens it throws UnhandledException (earlier it was working fine). I am not getting much exception details. What's wrong with the chart?
System.Exception
   at Windows.UI.Xaml.UIElement.Measure(Size availableSize)
   at WinRTXamlToolkit.Controls.DataVisualization.Charting.Primitives.EdgePanel.MeasureOverride(Size constraint)   at Windows.UI.Xaml.FrameworkElement.MeasureOverride(Size availableSize)

"Error HRESULT E_FAIL has been returned from a call to a COM component."
Here's code to regenerate it. I am doing all the stuff in code behind because in real there would be dynamic chart.

XAML
<Page.Resources>
    <Style TargetType="charting:ColumnDataPoint" x:Key="MyColumnDataPointStyle">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="charting:ColumnDataPoint">
                    <Grid>
                        <ToolTipService.ToolTip>
                            <ContentControl>
                                <TextBlock Text="{Binding Tooltip}" TextAlignment="Center" />
                            </ContentControl>
                        </ToolTipService.ToolTip>
                        <Rectangle Fill="{Binding Color}" Stroke="{Binding Color}" StrokeThickness="3" />
                    </Grid>
                </ControlTemplate>
