When you try to set the LabelDefinition property in style it is not applied.

As a workaround you can create an attached property to which you can apply the custom definition and set it to the LabelDefinition property of the annotation in its OnPropertyChangedCallback.

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).

Please add a feature for justifying the bar series chart so that bar data points can be plotted with a "Left", "Right", or "Center" justification to chart ticks.

An image to describe a "Right" vs "Center" bar justification is provided.

Add support for ScatterBar series type i.e. bar series that is plotted against linear / logarithmic axis.

      How can I hide the point in the lineSeries with the large data,and then zoom in by mousewheel,the point can be show in the lineSeries,when zoom out again,the point can be hide.
     Because with large data in a view,if show the point, the lineSeries's performance is poor,and the details area is not necessary,only when zoom in,we hope to show the point.

On a desktop device the tooltip is shown when the mouse enters the data point's visual element. On touch device the tooltip should be displayed when you tap (or tap and hold) on the visual element. Currently, this doesn't work. 

To work this around you can implement custom tooltip behavior using RadToolTip and TouchManager.

During Series animation, the stroke of the AreaSeries (area, splinearea, scatterarea, steparea) is not animated.

Add support for chart series animations.

This reproduces when the axis' SmartLabelMode is enabled. For example, set to SmartStep. 

See the attached video.

As a workaround you can disable the smart label mode and manually calculate the range when zooming. You can use its Minimum, Maximum, MajorStep and MajorStepUnit properties.

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.

Introduce a way to set a geometry for the chart series' data points. Currently you cannot easily change the geometry of the default visual of PointSeries and LineSeries, for example. We can also introduce a default visual geometry selector.

Expose RadFunnelChart and RadFunnelSeries for displaying funnel-like segments. They are usually used for visualizing stages in sales / marketing processes.

The exception is reproduced only if the Visibility is initially bound to a property that returns Collapsed.

This can be reproduce with the chart indicators that derives from LineIndicatorBase. For example, MovingAverageIndicator or MomentumIndicator.

To resolve this you can bind the Opacity property instead of Visibility.

This is reproducible only when the chart's automation peers are used. For example, they are used by default when you use the chart on a touch screen. Or when an accessibility tool is used on the application with the chart.

You can work it around by disabling the auto peers (http://docs.telerik.com/devtools/wpf/common-ui-automation).

AutomationManager.AutomationMode = AutomationMode.Disabled;

When the points in a series consist of values including 0, DivideByZeroException is thrown. The exception is thrown while measuring the chart - the tick step is set to 0 and the index of the tick on the axis cannot be calculated.
 
Workaround: Set the Minimum and Maximum properties of the Axis.

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