Legend Items are missing...

[Rob]

Hello,

I have found a bug (I think) in the RadChart control...  For several months now, we have been using the RadChart like follows:

<telerik:RadChart x:Name="RadChart" Grid.Row="2" Grid.Column="0" Grid.ColumnSpan="4" telerik:AnimationManager.IsAnimationEnabled="False" ItemsSource="{TemplateBinding Items}" MinFullHeight="100" MinFullWidth="100" MaxWidth="425" MaxHeight="300" Style="{StaticResource rc_style}" Background="#FFFFFFFF" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch">
   <telerik:RadChart.DefaultView>
      <telerik:ChartDefaultView>
         <telerik:ChartDefaultView.ChartArea>
            <telerik:ChartArea>
               <telerik:ChartArea.AnimationSettings>
                  <telerik:AnimationSettings ItemDelay="00:00:00.0" ItemAnimationDuration="00:00:00" />
                  </telerik:ChartArea.AnimationSettings>
               </telerik:ChartArea>
            </telerik:ChartDefaultView.ChartArea>
         </telerik:ChartDefaultView>
      </telerik:RadChart.DefaultView>
</telerik:RadChart>

Recently, we noticed that the legend items were not showing...  After some trial and error, I discovered that removing the animcation settings fixed the problem...  Can you tell me why?  I don't recall exactly why we were setting the animationsettings in the first place, or else I would just remove it.

<telerik:RadChart x:Name="RadChart" Style="{StaticResource rc_style}" Grid.Row="2" Grid.Column="0" Grid.ColumnSpan="4" telerik:AnimationManager.IsAnimationEnabled="False" ItemsSource="{TemplateBinding Items}" MinFullHeight="100" MinFullWidth="100" MaxWidth="425" MaxHeight="300"  Background="#FFFFFFFF" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch">
</telerik:RadChart>

Please see the attached screenshot of "working" and "hidden" legend items...

Hello Rob,

The reason the ChartLegend is not displayed is actaully because by defining a ChartDefaultView, you are overriding the default one - which conatins a ChartLegend. As you can see in this help topic, when defining a ChartDefaultView, if you want a ChartLegend, you have to define one and also you have to tell the ChartArea to use is by setting its LegendName property.
