PyBinding MarkupExtension: use Python statements for Data Binding
A very nice extension built for WPF, Read the full details Here.
E.g. -
<Polyline Points="{ln:PyBinding PointCollection([Point(p.Time,
p.Value * $(Container.ActualHeight))
for p in $(.MarketData.DataPoints)])}"
Stroke="IndianRed" StrokeThickness="1" />
Very cool!
