Axis color/stroke, tick length, ticks, frequency, count
Axis label rotation

Add arbitrary annotations at any point on a chart area (including points not in the main series)
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
