Fixed in LIB version: 2014.2.0913

When changing the Items of the legend - the legend flickers. The reason for this is that there is RelativeSource binding for the ContentTemplate of the LegendItemControl, and for the binding to work - the legend item control needs to be in the visual tree. And the binding kicks in after the legend item control is added to the visual tree. 

Workaround: 
Create an implicit style targeting the LegendItemControl and use a Setter as suggested below:
<telerik:RadLegend.Resources>
 <Style TargetType="telerik:LegendItemControl">
  <Setter Property="ContentTemplate" Value="{Binding ItemTemplate, RelativeSource={RelativeSource AncestorType=telerik:RadLegend}}" />

ElementName bindings are not resolved correctly for ItemMapping object when RadChart is placed inside TabControl.

CameraExtention doesn't work with late binding - Async data loading from WCF service.

When rendering Line3D with constant YValue the visuals do not appear as expected and a significant delay is observed.

Chart: X axis zoom is ignored when grouping.

ConvertDataUnitsToPhysical functionality should be able to return results relative to the entire chart, so that a user can place an object over it.

REASON FOR DECLINATION
This is supported out-of-the-box by the new RadChartView.

Having Series Mapping, a specific XCategory needs to be highlighted.

REASON FOR DECLINATION
This is supported out-of-the-box by the new RadChartView (use the LabelTemplateSelector of the axes).

This event should be fired even when the axis is collapsed.

Chart: X axis min value changes when moving the right slider handle

Chart: Add nearest points outside the zoom area to the graph.

Chart: AxisX.ActualMinValue is incorrect when zooming (AutoRange=false)

Range series style is applied according to X axis ticks.

If there is another Theme set to the Control, it is not applied correctly to the series and the axes.

Edit: Please use ChartView and implicit styling instead if possible.

Chart: bars too wide in strict mode. This is partially fixable by decreasing TicksDistance. Still, no fix when AxisX.Visibility is set to Collapsed.
