Chart is not exported properly when Margin is present.

Bar series with DateTimeContinuousAxis axis with no MajorStep specified. When you zoom the bars gets to big and does not stay within its tick boundaries.

When adding two BarSeries in code-behind, the second one is not aligned well on the horizontal DateTimeContiniousAxis. It starts from the beginning of the axis, but not the supposed DateTime.

Pan/zoom behavior should be configurable whether to execute its logic on right mouse button or left mouse button down.

CategoricalSeriesDescriptor.TypePath is not currently bindable. This means this has to point to a property on your DataSource that returns Telerik series types. This breaks the MVVM design model, as the DataSource points to the ViewModel, that should not contain any View specific types. Please provide a bindable alternative, such that a Converter can be applied to supply the View specific types.

Will be available in Q1 2016 Release.

NullReferenceException on updating data when mouse is over chart's area and trackballinfo is visible. 

To workaround this, remove the TrackBallBehavior when data is updated and add it again on MouseMove.

Will be available in Q1 2015 Release.

If you set the PolarAxis.Maximum property to value which is equal to or less than the smallest value of a series, a DevideByZero exception is thrown.

Fixed in Q3 2014

A design time exception may be thrown in certain scenarios.

Available in LIB Version 2015.2.907.

The fix is available in LIB Version 2015.1.0420.

When there are no data points in the bar series, the chart fails to retrieve a color for the marker of the legend item. This can be worked around by modifying the item template of the legend item. In the new template the binding of the Fill of the marker, should include not just the MarkerFill but TargetNullValue:

<DataTemplate x:Key="legendItemContentTemplate1">
 <StackPanel Orientation="Horizontal">
  <Path Fill="{Binding MarkerFill, TargetNullValue=#9B25B1}" Width="12" Height="12">
   <Path.Data>
    <Binding Path="ActualMarkerGeometry" 
      RelativeSource="{RelativeSource AncestorType=telerik:LegendItemControl}" />
   </Path.Data>
  </Path>
  <TextBlock Margin="2" Text="{Binding Title}" />
 </StackPanel>
</DataTemplate>


Will be available in Q2 2016 Release.

A NullReferenceException is thrown when the Strategy of the series is set

Add support for 3D Series Type in RadChartView.

A RadCartesianChart3D was introduced with R3 2016. You can use its BarSeries3D to easily achieve the Manhattan chart visualization.

See the documentation: 
http://docs.telerik.com/devtools/wpf/controls/radchartview3d/overview
See the SDK examples: 
https://github.com/telerik/xaml-sdk/tree/master/ChartView3D/WPF
See the demos: 
https://demos.telerik.com/wpf/

If the annotation and its label are out of the viewport (the plot area) and then use the PanZoomBar to scroll to it, the label is not displayed. It appears after the chart layout is updated (ex: resize or zoom).

The trackball becomes unresponsive in a live data scenario with more than one chart. The issue is observed in a scenario with a categorical axis and grid lines originating from it. 

The fix is available in LIB Version: 2016.2.829.

When a linear axis is used with the same ticks (ticks number and ticks position), and the same plot mode as a categorical axis (BetweenTicks or OnTicks) - the width of the bars is different and is slightly smaller with the linear axis.


Available in LIB version: 2016.3.1017

The exception is reproducible when you are using SplineSeries with DateTimeContinuousAxis. You need to add data points to the chart with a gap between the dates.
