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).

In a multiple series scenario if one series gets removed, an internal axis flag is incorrectly reset resulting in the horizontal axis displaying only one label when SmartLabelsMode is used. One way to work-around this is to add an empty dummy series after removing a real series:

            this.chart1.Series.Remove(EmptyDummySeries);
            if (this.chart1.Series.Count > 0)
            {
                this.chart1.Series.RemoveAt(this.chart1.Series.Count - 1);
                if (this.chart1.Series.Count > 0)
                {
                    this.chart1.Series.Add(EmptyDummySeries);
                }
            }

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

Workaround: Bind the UpStroke and DownStroke properties of the Candlestick via custom style (which is set to the DefaultVisualStyle property) to properties from the model. Then in the setter of the Close property, can set different color depending on whether the Close is less than Open property.

Currently, if the trackball position is outside the plot area boundaries, the element is not clipped and there is no mechanism that allows clipping it. 

Note: The trackball is the small ellipse that snaps to the data points.

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.

When you change series datapoints and then play ChartRevealAnimation the following InvalidOperationException might occur:

 Cannot call the ClockController.SkipToFill method for a Clock that has a Duration or RepeatDuration of Forever, because this Clock will never reach its fill period.
=====
Workaround:
You can try calling PlayAnimation in Dispatcher:

  Dispatcher.BeginInvoke(new Action(() =>
            {
                this.LineSeries1.PlaySeriesAnimation();
            }));

The ToolTip behavior respect how the series are added to the chart. Setting ZIndex property to reorder them will not be respected by the ToolTip.

Currently, the PanZoomBar is not themed across the themes. Consider improving this by applying different colors to the Thumbs based on the applied theme.

When you set the Palette property to a new instance of ChartPalette in XAML, a NullReferenceException is thrown. This happens when you click inside the chart control in the Visual Studio designer.

The exception reproduces only if the "Miscellaneous" category in the "Properties" pane of Visual Studio is expanded.

To work this around, set the Palette property in code:

C#:

VB.NET:

 

 

The start point of the MoveAnimation(Top and Left) is not calculated correctly.

Currently, you can format the axis labels using the LabelFormat property. This allows the same format to display different label value for the different cultures when the UI culture is changed. 

Add support also for the Language framework property in this case. 

It appears the ChartView is also affected by the same SharpDX issue that affected the RadWebCam when it is used over Remote Desktop. 

A simple test of any series will replicate the issue. If it is being used via Remote Desktop, the series will not render.

Allow setting OriginValue on the series in the RadPolarChart. Currently, the area series are fixed to OriginValue of 0.

The same feature is available in the RadCartesianChart series.

The Telerik.Windows.Controls.Chart.Direct2D.dll is missing from the nuget package file containing all Telerik dlls (Telerik.UI.For.Wpf).

When the application starts, the PointAnimation isn't played on PieSeries in a data-bound scenario. Also, this will hide the labels of the segments.

Currently, you can customize the fill and stroke of the data point visuals using the DefaultVisualStyle property of the series. In the common scenario, you can use data bindings to data bind the fill and stroke of the corresponding element. Additionally, you can use the DefaultVisualStyleSelector for such customization. However, when the Direct2DRenderOptions or BitmapRenderOptions are used, data bindings and the DefaultVisualStyleSelector are not support. The bindings in the DefaultVisualStyle throw errors and the selector is not applied.

Add support for conditional styling. This should include support for data binding in the fill and stroke properties of the element from the DefaultVisualStyle, or support for DefaultVisualStyleSelector, or another type of API.
