Hit testing on points in series. gives point, series, series index, point index, supports touch
RenderInfo for each chart area available, giving scale, offsets, visible ranges allowing you to transform to/from the render and data coordinate spaces
MinorTickCount: Ability to specify a minor tick count between major ticks Gridlines (from major ticks), stroke/alternating fill colors.

Data:
Supports dates, integers, and floating point data, plus labels for series and points 
Encourages data-driven charting - example data adapters for Stacked and Stacked-to-100% (with built in support for stacking with all appropriate chart types)
Supports LINQ projections into chart series 
Optimized updates for changing data.

Axes:
Multiple fixed and floating axes can all be controlled independently 
Automatic, manual, or semi-manual axis range detection 
Ability to ensure that zero is always within the range 
Customizable axis label format 
Axis color/stroke, tick length, ticks, frequency, count 
Axis label rotation

Annotations:

Supports binding to a view model associated with a datapoint, with AnnotationContentTemplate and AnnotationContentTemplateSelector so you can render arbitrary visuals/interactions

Zoom & Scroll: 
Ability to zoom and scroll around arbitrary X/Y subsets of the data
Automatic axis positioning while zooming (if floating, picks floating/anchored based on current minima/maxima in visible region)
Supports touch

Trendlines:
Ability to add y = mx + c or x = c trendlines to the graph, with Stroke, StrokeThickness and DashArray.
(Clearly, additional chart areas or annotations could be used for alternative trend lines)

Error bars:
Ability to add high/low error bars to y-axis values

Highlighting and selection:
Supports automatic and manual highlighting and selection

Performance:
Encourages clean, simple presentation of data (although you can go mad with the styling if you want)
Minimizes the number of visuals in the tree
