hashCode → int
The hash code for this object.
no setterinherited
index ↔ int
在图表中的位置
getter/setter pairinherited
isInit ↔ bool

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
startAngle → double
开始弧度，可以调整起始位置
final
strokeCap → StrokeCap?
结尾样式
final
strokeWidth → double
线宽
final
yAxisPosition → int
跟哪个y轴关联
