g2 动态条形图 颜色排序随Y轴数据变换而变换 #3612

• I have searched the issues of this repository and believe that this is not a duplicate.

What problem does this feature solve?

https://g2.antv.vision/zh/examples/case/dynamic#dynamic-bar 官方示例里面 changeData() 颜色的排序并不随y轴值的变换而变换，观感上会有“数据的排序并没有改变” 虽然可以clear()再重新设置图表。但重新加载图表会破坏动态数据变化时图表的连贯性

What does the proposed API look like?

color() 添加 "颜色位置变换"option https://g2.antv.vision/zh/examples/case/dynamic#dynamic-bar 官网示例里面 颜色的排序并不随y轴值的变换而变换
