FitGridCellVisualSpec.bar constructor
const
FitGridCellVisualSpec.bar({})
A bar spanning from to to across the cell — from the zero line to
the value, so a negative value extends the other way.
Implementation
const FitGridCellVisualSpec.bar({
required this.from,
required this.to,
this.negative = false,
this.color,
}) : kind = FitGridVisualKind.bar,
points = const <double>[],
filled = false;
