StackBar<T> class

stackBar 支持水平/垂直排列

Inheritance
Mixed in types

Constructors

StackBar({required List<T> data, required ChartPosition<T> position, required StackBarPosition<T> values, int yAxisPosition = 0, Color? highlightColor = Colors.yellow, List<Color> colors = colors10, List<Shader>? shaders, double itemWidth = 20, Axis direction = Axis.horizontal, bool full = false, double padding = 5, Color? hotColor, BarValuesFormatter? valuesFormatter, TextStyle textStyle = const TextStyle(fontSize: 10, color: Colors.black), Offset valueOffset = Offset.zero})

Properties

chartState ↔ ChartLayoutState
图表的布局状态
getter/setter pairinherited
colors → List<Color>
多个颜色
final
controller ↔ ChartController
getter/setter pairinherited
data → List<T>
数据源
finalinherited
direction → Axis
方向
final
full → bool
撑满 如果为true则会根据实际数值的总和求比例，如果为false则会根据Y轴最大值求比例
final
hashCode → int
The hash code for this object.
no setterinherited
highlightColor → Color?
高亮颜色
final
hotColor → Color?
绘制热区 颜色
final
index ↔ int
在图表中的位置
getter/setter pairinherited
isInit ↔ bool
getter/setter pairinherited
itemWidth → double
bar的宽度
final
padding → double
两个bar之间的间距
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
final
textStyle → TextStyle
值文字样式
final
valueOffset → Offset
文案偏移
final
values → StackBarPosition<T>
值格式化
final
valuesFormatter → BarValuesFormatter?
值文案格式化 不要使用过于耗时的方法
final
yAxisPosition → int
跟哪个y轴关联
finalinherited

inherited
lerpList(List<num>? a, List<num>? b, double t) → List<num>?
inherited
noSuchMethod(Invocation invocation) → dynamic
