Inheritance
Mixed-in types

Constructors

Line({required List<T> data, required ChartPosition<T> position, required LinePosition values, int yAxisPosition = 0, List<Color> colors = colors10, List<Shader>? shaders, List<Color>? dotColors, double dotRadius = 2, double strokeWidth = 1, bool isHollow = false, bool? filled = false, bool isCurve = false, PathOperation? operation, bool async = false})

Properties

async → bool
是否异步初始化布局
final
chartState ↔ ChartLayoutState
图表的布局状态
getter/setter pairinherited
colors → List<Color>
线颜色
final
controller ↔ ChartController
getter/setter pairinherited
data → List<T>
数据源
finalinherited
dotColors → List<Color>?
点的颜色
final
dotRadius → double
点半径
final
filled → bool?
是否填充颜色 true：填充，false：不填充 默认false
final
hashCode → int
The hash code for this object.
no setterinherited
index ↔ int
在图表中的位置
getter/setter pairinherited
isCurve → bool
是否是曲线 默认false
final
isHollow → bool
是否有空心圆
final
isInit ↔ bool
getter/setter pairinherited
operation → PathOperation?
路径之间的处理规则
final
position → ChartPosition<T>
不要使用过于耗时的方法 数据在坐标系的位置，每个坐标系下取值逻辑不一样，在line和bar下是相对于每格的值，比如xAxis的interval为1，你的数据放在1列和2列中间，那么position就是0.5，在pie下是比例
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
shaders → List<Shader>?
优先级高于colors 跟filled有关，false是折线的颜色，true是填充色
final
strokeWidth → double
线宽
final
values → LinePosition
每个点对应的值 不要使用过于耗时的方法
final
yAxisPosition → int
跟哪个y轴关联
finalinherited

Methods

asyncInitWithOutAnimal(ChartsState state) → Map<int, LineInfo>
inherited
draw(Canvas canvas, ChartsState state) → void
inherited
getLastData(bool need) → List<ChartItemLayoutState>?
inherited
init(ChartsState state) → void
初始化 耗时的方法都可以放到这里
lerpList(List<num>? a, List<num>? b, double t) → List<num>?
inherited
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.
