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.

ChartDataSource control should perform the sampling operation asynchronously in a background thread so that it is not blocking the UI thread.

"Insert" operation is not supported properly for chart series but is handled like "Add" i.e. RadCartesianChart.Series.Insert(0, series) will not result in inserting the series at zero index but internally it will be added to the end of the collection and it will be treated as last series.

Available in version 2014.3.1215.

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.

When adding two BarSeries in code-behind, the second one is not aligned well on the horizontal DateTimeContiniousAxis. It starts from the beginning of the axis, but not the supposed DateTime.

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

Users should be able to create custom financial indicators.

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.

Decline reason: This item is duplicate of the following one:

Extend ChartSelectionBehavior to support continuous range selection through drag&drop.

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

Add support for chart series animations.

Add support for ScatterBar series type i.e. bar series that is plotted against linear / logarithmic axis.

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.

When this mode is on - all of the points for which information in the track ball is shown should be on the left hand side of the mouse.

Add support for 3D Surface Series Type.

This feature is now available as part of the ChartView control since R3 2016 Official release. Refer to the link below for more information.
http://docs.telerik.com/devtools/wpf/controls/radchartview3d/series/surfaceseries3d.html

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

PlotArea occasionally stops refreshing in live data scenario with asynchronous updates (multithreading).

Numeric axes should be able to specify their PlotMode as categorical axes do (currently numeric axes use hardcoded OnTicks plot mode).

Add support for tooltip visualization over the continuous series segments that would interpolate the actual value between data points.

XAML Team reviewed this request and decided not to address it in the future. Appropriate way to get this is to use the crosshair behavior.

Add support for tooltip visualization over the continuous series segments (besides the current support for visualizing the tooltip over the actual data point / point mark).

Declined due to duplication with http://feedback.telerik.com/Project/143/Feedback/Details/113405-chartview-enhanced-tooltip-support-for-continuous-series-segments-line-area-e
