I love it when people ask questions we can answer straight away 🙂
The answer is yes – we have a feature in FastLineRenderableSeries called DrawNaNAs. When this is set, and you change the Y-Value of a data-point to double.NaN (or float.NaN) then the line will draw a gap, or close the line between two points.
This is demonstrated in our Gaps in Series example.
Hope this helps!
