Constructors

RadarChartData({@required List<RadarDataSet>? dataSets, Color? radarBackgroundColor, BorderSide? radarBorderData, RadarShape? radarShape, GetTitleByIndexFunction? getTitle, TextStyle? titleTextStyle, double? titlePositionPercentageOffset, int? tickCount, TextStyle? ticksTextStyle, BorderSide? tickBorderData, BorderSide? gridBorderData, RadarTouchData? radarTouchData, FlBorderData? borderData})

RadarChart draws some dataSets in a radar-shaped chart. it fills the radar area with radarBackgroundColor and draws radar border with radarBorderData then draws a grid over it, you can customize it using gridBorderData.

Properties

borderData → FlBorderData

Holds data to drawing border around the chart.

final, inherited

dataSets → List<RadarDataSet>

RadarChart draw dataSets that each of them showing a list of RadarEntry

final

getTitle → GetTitleByIndexFunction?

getTitle is used to draw titles outside the RadarChart getTitle is type of GetTitleByIndexFunction so you should return a valid RadarChartTitle for each index (we provide a default angle = index * 360 / titleCount)

final

gridBorderData → BorderSide

Defines style of showing RadarChart grid borders.

final

hashCode → int

The hash code for this object.

no setter, inherited

maxEntry → RadarEntry

defines the maximum RadarEntry value in all dataSets we use this value to calculate the maximum value of ticks.

no setter

minEntry → RadarEntry

defines the minimum RadarEntry value in all dataSets we use this value to calculate the minimum value of ticks.

no setter

props → List<Object?>

Used for equality check, see EquatableMixin.

no setter, override

radarBackgroundColor → Color

radarBackgroundColor draw the background color of the RadarChart

final

radarBorderData → BorderSide

radarBorderData is used to draw RadarChart border

final

radarShape → RadarShape

radarShape is used to draw RadarChart border and background

final

radarTouchData → RadarTouchData

Handles touch behaviors and responses.

final

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

tickBorderData → BorderSide

Defines style of showing RadarChart tick borders.

final

tickCount → int

Defines the number of ticks that should be paint in RadarChart the default & minimum value of this field is 1.

final

ticksTextStyle → TextStyle?

Defines style of showing RadarChart tick titles.

final

titleCount → int

titleCount we use this value to determine number of RadarChart grid or lines.

no setter

titlePositionPercentageOffset → double

the titlePositionPercentageOffset is the place of showing title on the RadarChart The higher the value of this field, the more titles move away from the chart. this field should be between 0 and 1, if it is 0 the title will be drawn near the inside section, if it is 1 the title will be drawn near the outside of section, the default value is 0.2.

final

titleTextStyle → TextStyle?

Defines style of showing RadarChart titles.

final

touchData → FlTouchData<BaseTouchResponse>

Holds data needed to touch behavior and responses.

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

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

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