ChartView: Implement radar column series.

Allow for the Polar chart to have multiple polar axes so that a user can easily understand what value does a data point have. For example a polar chart with four axes (with the same range) and an axis in each quadrant.

Provide way for specifying a minimum effective size of the zoom rectangle, so that accidental clicks can be ignored.

Support for displaying error bars

Add support for axis with multi-level categories.

RadPieChart labels are clipped when RadiusFactor is 1.0

Add support for millisecond sampling interval to ChartDataSource.

Currently in live data scenarios the TrackInfoControl does not update its content unless the mouse is moved. The track ball should get updated automatically when the DataPoints are modified.

If we set a Palette to RadCartesianChart and then modify the default StrokeThickness and Stroke of a LineSeries via Style, the new Stroke does not apply. The project attached demonstrates the problem.

Implement ChartSeriesLabelDefinition properties as DependencyProperties

Set the DataContext of a Candlestick to be the DataPoint to allow binding to properties of the business object.

Provide the option for displaying axes at both sides of the plot area at the same time.

When this mode is on, information should be displayed for all data points in a given category (as opposed to displaying the closest points taken from different categories).

ChartView: Add support for axes rendering, when no data is available

As a workaround add a series with one point and set its color to transparent.

<telerik:ScatterLineSeries XValueBinding="."
                  YValueBinding="."
                  Stroke="Transparent">
    <telerik:ScatterLineSeries.ItemsSource>
        <x:Array Type="system:Int32">
            <system:Int32>0</system:Int32>
        </x:Array>
    </telerik:ScatterLineSeries.ItemsSource>
</telerik:ScatterLineSeries>

When the CartesianPlotBand annotation is bound to the vertical axis its 'From' value doesn't align with the axis.
This changes when resizing.

Add support for categorical PointSeries type (i.e. ScatterPointSeries equivalent that supports DateTime data.

Currently when sampling is used to generate the data points, the DataItem property of the DataPoint is null and there is no way to find out which data items have been used to generate the data point. A new property can be introduced (DataItems) which can contain the data items in mind.

Available in R1 2017 Release

Allow Area ( and ScatterArea ) series origin to be set at a number, different than 0

Possible positions: 
- above or below the X axis 
- left or right of the Y axis

Add grid line style selector
