Methods

calculateHeightForRotatedLabel(int rotation, double labelHeight, double labelLength) → double
Returns the height of a rotated labels on a domain axis.
calculateWidthForRotatedLabel(int rotation, double labelHeight, double labelLength) → double
Returns the width of a rotated labels on a domain axis.
collides(List<Tick<D>>? ticks, AxisOrientation? orientation) → CollisionReport<D>
Returns a CollisionReport indicating if there are any collisions.
override
decorateTicks(List<Tick<D>> ticks) → void
Decorate the existing list of ticks.
override
draw(ChartCanvas canvas, Tick<D> tick, {required AxisOrientation orientation, required Rectangle<int> axisBounds, required Rectangle<int> drawAreaBounds, required bool isFirst, required bool isLast, bool collision = false}) → void
Draws tick onto ChartCanvas.
