Methods

buildFromPoints(List<ChartPoint> points, CoordinateTransformer transformer, {bool smooth = true, bool close = false}) → Path

Builds path from chart points using a coordinate transformer.

buildMonotonePath(List<Offset> points, {bool close = false}) → Path

Builds a smooth path using monotone cubic interpolation (Fritsch–Carlson). Unlike a cardinal spline, this never overshoots the data: the curve introduces no false peaks, no dips below a local minimum, and stays within the value range between points — so a smoothed line remains a faithful reading of the data.

buildSmoothPath(List<Offset> points, {bool close = false}) → Path

Builds a smooth cubic Bezier path through transformed points.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.
