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

Gaps appear between the bars in the stacks when the series are populated with negative and positive values. Check the attached picture.

If you have a scenario with mixed values (positive and negative) use RangeBarSeries instead of BarSeries.

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.

An InvalidCastException is thrown in the Fill/Background property binding in the series' DefaultVisualStyle when the RenderOptions is set to Bitmap or Direct2D.

Create 2-dimensional contour plot from unstructured 3-dimensional data.  Means the points are randomly arranged in the XY plane.

Attached file shows an example of what I would like to achieve.  I think the contour plot Telerik does currently requires a structured grid, i.e. full grid of NxM points.

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;

The exception can be observed when you a plot data point with value that falls outside of the range of the Decimal type.

As a workaround you can coerce the data before give it to the chart.

The exception is reproducible when the chart contains series with RenderOptions=Direct2DRenderOptions.

The error message is:

HRESULT: [0x8876086A], Module: [SharpDX.Direct3D9], ApiCode: [D3DERR_NOTAVAILABLE/NotAvailable], Message: Unknown

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.

Some of the data points plotted in the chart are not positioned as expected in a scenario with DateTimeContinuousAxis with SmartLabelsMode=SmartStep and PlotMode=OnTicksPadded or BetweenTicks.

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.

Allow to track points that intercept vertical line from mouse position (as now)  or points that intercept horizontal line from mouse position.
So allow to choose TrackDirection = Horizontal/Vertical

Thanks.

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.

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.
