Add built-in support for smart series item labels i.e. automatic label arrangment that ensures the labels do not overlap.

Introduce Annotations ItemsSource property

Available in Release Version Q1 2016.

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

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

Knowing where the cursor is and the associated coordinate and data information is critical to really create highly functional finacial chart. It allows the developer to overlay order tools on the chart like trendlines, possibly even enables the end-user to place an order directly from chart.

- Enhance cartesian chart interactivity by enabling the usage of TrackballInfo features without actually showing the trackball e.g. show the OHLC info in the top left corner of the chart (add mouse down/move events as well).
- Enable scenarios that need to pass trackball info to other charts e.g. on chart #1 you want to show trackball info for chart #2 at the same time (knowing the trackball info and coordinates of each chart is critical to syncing the track info of another chart that may be below the main chart as stock would want to see the tracking info for all chart simultaneaously).

Available in Q2 2015 Release.

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

Add support for automatic step calculation for the chart's axes.

Available in Q2 2015 Release.

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 RangeSeriesDescriptor

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! 

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.

Currently it is only possible to get the Actual Minimum and Maximum of the Linear axis, but it is not possible to track change notifications. Needed properties should be introduced so that it is possible to track the Actual Min and Max (with and without the ZoomAndPan behavior).

Available in Q3 2014 SP1 Release.

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.

Automatic axis range calculation should take into account the visibility of the chart series (i.e. the data points of a collapsed series should not be respected).

Note: This is by design. The range of all series forms the range of the axis. If the user wants the collapsed series not to affect the range of the axis he can remove them.

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

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

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