Error when using LabelRotationAngle

[Stuart]

Hi

I have a simple chart declared declaratively and bound to my viewmodel using the following

<telerik:RadChart ItemsSource="{Binding Data}" Margin="10" Padding="10">
                    <telerik:RadChart.DefaultView>
                        <telerik:ChartDefaultView>
                            <telerik:ChartDefaultView.ChartArea>
                                <telerik:ChartArea>
                                    <!--<telerik:AxisX LabelRotationAngle="90" />-->
                                </telerik:ChartArea>
                            </telerik:ChartDefaultView.ChartArea>
                        </telerik:ChartDefaultView>
                    </telerik:RadChart.DefaultView>
                    <telerik:RadChart.SeriesMappings>
                        <telerik:SeriesMapping LegendLabel="Label1">
                            <telerik:SeriesMapping.SeriesDefinition>
                                <telerik:BarSeriesDefinition ShowItemLabels="True"/>
                            </telerik:SeriesMapping.SeriesDefinition>
                            <telerik:SeriesMapping.ItemMappings>
                                <telerik:ItemMapping DataPointMember="XCategory" FieldName="Country"/>
                                <telerik:ItemMapping DataPointMember="YValue" FieldName="Value1"/>
 
                            </telerik:SeriesMapping.ItemMappings>
                        </telerik:SeriesMapping>
                    </telerik:RadChart.SeriesMappings>
                </telerik:RadChart>

In addition I would like to rotate the category values along the bottom by 90 degrees. However when I uncomment the line with the LabelRotateAngle attribute in suddenly my whole SLapp collapses and refuses to render the page - it complains about the itemsource not being empty etc.


Can anyone help?

Thanks

Okay, ignore me, I've seen the error of my ways.

I had to use

<telerik:ChartArea.AxisX>
    <telerik:AxisX LabelRotationAngle="90"/>
</telerik:ChartArea.AxisX>

rather than what I had above.

Thanks anyway
