Implement Scatter 3D series type that can plot data again X-Y-Z coordinate system (real Z axis).

Zooming & Scrolling is incorrect in datasets with clustered data and large gaps between the clusters.

Add support for gridlines and striplines for additional y axis.

There is a design time issue when binding to null collection with series mappings / itemmappings defined in XAML (MVVM).

It is currently possible to mousedown in a chart area, leave the RadChart with the mouse, and start interacting with other controls, and the RadChart will still await a mouseup event to stop Zooming / Scrolling. If a RadChart loses focus, it should resolve

If you set the following style: 
<Style x:Key="XAxisGridLineStyle" TargetType="Line">
    <Setter Property="StrokeThickness" Value="12" />
    <Setter Property="Stroke" Value="Black" />
</Style>

you get grid lines 50% thinner then the desired (6px).

Possibilities:
    *  The user double clicks on the orange part of the scroll bar, and it exapands to the full range.  
    * The user double clicks on one of the draggable handles and it returns to its end of the scroll bar.
    * When both scroll bars ar

If the the datetime field is a nullable type, no matter if it has a value, it throws a null reference exception.

Chart: AxisX should allow a single item with AutoRange =false

Interactivity API does not work in constructor, Loaded and DataBound events.

Chart: Allow AxisItem2D retemplating.

Expose HierarchyManager.Drill(...) method so the user can initiate drill-down action from code.

Expose public API for hover / highlight interactivity from code (currently hover action is triggered only if you physically move the mouse over the chart item).

Minor ticks are not displayed correctly when using logarithmic scale.

Chart series always show 0 values when bound to a dynamic object

See attached project

Allow the user to drag the chart area and perform panning in this was as an alternative to dragging the scrollbar.

Introduce functionality for getting the default colors programatically.

In statistics, a moving average, also called rolling average, rolling mean or running average, is a type of finite impulse response filter used to analyze a set of data points by creating a series of averages of different subsets of the full data set.

Add support for trendline curves that have the best fit to a series of data points, possibly subject to constraints (e.g. linear / quadratic / cubic fit curves, etc.)
