Methods

createPainter() → SeriesPainter<MarkerSeries>

Is called whenever series is created to create its seriesPainter as well.

override

didUpdate(ChartData? oldData) → bool

Always returns false because marker changes do not drive tick animations; only the main series result is used for that purpose.

override

getMaxEpoch() → int?

Maximum epoch of this ChartData on the chart's X-Axis.

override

getMinEpoch() → int?

Minimum epoch of this ChartData on the chart's X-Axis.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

onUpdate(int leftEpoch, int rightEpoch) → void

Updates series visible data.

override

paint(Canvas canvas, Size size, double epochToX(int), double quoteToY(double), AnimationInfo animationInfo, ChartConfig chartConfig, ChartTheme theme, ChartScaleModel chartScaleModel) → void

Paints seriesPainter's data on the canvas.

inherited

recalculateMinMax() → List<double>

Calculate min/max values in updated data

override

shouldRepaint(ChartData? previous) → bool

Checks if this ChartData needs to repaint with the chart widget's new frame.

inherited

toString() → String

A string representation of this object.

inherited

update(int leftEpoch, int rightEpoch) → void

Updates visible entries for this Series.
