I would like to be able to create a histogram where both the x and y axis are linear series and where I can specify the start and end position of each bin (not just one). Previously described workarounds include using StepLineSeries and bar series which cannot have two linear series. I cannot use a scatter plot series as they do not provide the step-wise look of the histogram.  Please add this support! 

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>

Support for displaying error bars

Add the option for having separate PanZoomBars for each axis, so the user can scroll/zoom each axis independently from the other axes.

Add support for BoxPlot series type either through enabling extensibility of the CandlestickSeries type, or through providing new built-in BoxPlot series type.

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.

If two or more data points from the same series have the same X value - it should be possible to show information for all of these data points in the track ball.

Add support for chart series animations.

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

Introduce Annotations ItemsSource property

Available in Release Version Q1 2016.

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

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.

Implement RangeSplineAreaSeries

Add RangeSeriesDescriptor

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