WPF issue with custom tooltips flashing over and over if they are associated with chart items that physically are placed in the lower-right corner of the monitor (i.e. the app window should be maximized to observe the undesirable behavior).

Implement pyramid series type in RadChart.

The user needs to disable the "select an area" zooming and to keep the "resize the scrollbar" zooming technique.

Functionality for changing the origin to an arbitrary point needs to be add.

Dragging pie slices is not supported at present. The current implementation hooks the MouseLeftButtonDown event to manage the visual transition from selected to unselected state and vice versa. So it is not possible to integrate with other solutions where 

Line3d series is rendered incorrectly with in case of negative values(345938)

Chart: More graceful handling of negative values when using logarithmic Y Axis.

The RadChart for Silverlight doesn't show the top value of YAxis when Step = 0.2.

When you set SeriesDefinition.SeriesStyle, you need to Rebind() in order to have the chart updated.

Keep the underlying data item for sampling functions like First, Last, Min and Max.

Chart: Provide event for chart item mouse up.

More geometries need to be available as marked zones. Additional y axes support also is necessary.

Chart: Allow user styles for interactivity features.

Microsoft Excel has an "autorange" feature for 1) y-axis min, 2) y-axis max, 3) major unit and 4) minor unit, all working independently of each other while Telerik RadChart AutoRange sets all 4 of these properties collectively, or sets none at all if autor

The developer should be able to change the axis origin location in order to enable scenarios like this one:

- Essentially you have a list of negative numbers: 0, -10, -24, -35 and so on.
- If you want to show them as positive numbers (pointing upwards), y

Marked Zones and Custom Gridlines need to be separated in different layers.

Zooming works incorrectly when using AutoRange=true and CollectionIndex. The problem is also observed when dataitems in different series have independent XValues.

For a Pie chart there should be a way to have things grouped into an other group.  For example anything that makes up less than 5% of the total is grouped in an other group.

Chart: Allow legend labels formatting when grouping
