BarChart needs this class to render itself.

It holds data needed to draw a bar chart, including bar lines, colors, spaces, touches, ...

Constructors

BarChartData.new({List<BarChartGroupData>? barGroups, double? groupsSpace, BarChartAlignment? alignment, FlTitlesData? titlesData, BarTouchData? barTouchData, double? maxY, double? minY, double? baselineY, FlGridData? gridData, FlBorderData? borderData, RangeAnnotations? rangeAnnotations, Color? backgroundColor, ExtraLinesData? extraLinesData, int rotationQuarterTurns = 0, FlErrorIndicatorData<BarChartSpotErrorRangeCallbackInput> errorIndicatorData = const FlErrorIndicatorData()})

BarChart draws some barGroups and aligns them using alignment, if alignment is BarChartAlignment.center, you can define groupsSpace to apply space between them.

Properties

alignment → BarChartAlignment

Arrange the barGroups, see BarChartAlignment.

final

backgroundColor → Color

A background color which is drawn behind the chart.

final, inherited

barGroups → List<BarChartGroupData>

BarChart draws barGroups that each of them contains a list of BarChartRodData.

final

barTouchData → BarTouchData

Handles touch behaviors and responses.

final

baselineX → double

final, inherited

baselineY → double

final, inherited

borderData → FlBorderData

Holds data to drawing border around the chart.

final, inherited

clipData → FlClipData

clip the chart to the border (prevent draw outside the border)

final, inherited

errorIndicatorData → FlErrorIndicatorData<BarChartSpotErrorRangeCallbackInput>

Holds data for showing error (threshold) indicators on the spots in the different BarChartGroupData.barRods

final

extraLinesData → ExtraLinesData

Extra horizontal or vertical lines to draw on the chart.

final, inherited

gridData → FlGridData

final, inherited

groupsSpace → double

Apply space between the barGroups.

final

hashCode → int

The hash code for this object.

no setter, inherited

horizontalDiff → double

Difference of maxX and minX

props → List<Object?>

Used for equality check, see EquatableMixin.

no setter, override

rangeAnnotations → RangeAnnotations

final, inherited

rotationQuarterTurns → int

Rotates the chart by 90 degrees clockwise in each turn

final, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

stringify → bool?

If set to true, the toString method will be overridden to output this instance's props.

no setter, inherited

titlesData → FlTitlesData

final, inherited

verticalDiff → double

Difference of maxY and minY

Methods

copyWith({List<BarChartGroupData>? barGroups, double? groupsSpace, BarChartAlignment? alignment, FlTitlesData? titlesData, RangeAnnotations? rangeAnnotations, BarTouchData? barTouchData, FlGridData? gridData, FlBorderData? borderData, double? maxY, double? minY, double? baselineY, Color? backgroundColor, ExtraLinesData? extraLinesData, int? rotationQuarterTurns, FlErrorIndicatorData<BarChartSpotErrorRangeCallbackInput>? errorIndicatorData}) → BarChartData

Copies current BarChartData to a new BarChartData, and replaces provided values.

lerp(BaseChartData a, BaseChartData b, double t) → BarChartData

Lerps a BaseChartData based on t value, check Tween.lerp.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
