What problem does this feature solve?

有多个0/1的开关变量，能否用柱状图实现，效果为在一个竖轴上有多条柱，0/1为不同颜色交替，这个怎么实现？

What does the proposed API look like?

There are more than 0/1 switch variables, can be achieved with a bar chart, the effect is to have more than one column on a vertical axis, 0/1 for different colors alternate, how to achieve this?

给每个 item 设置不同的颜色？

可以两种颜色交替，但是开关量为0的时候没有柱体延伸，这样的话不就只有为1的值一直堆叠了么

可以给把开关量0和1设置为同一个值用来画图，这个值是无意义的，然后对 label 和 tooltip 进行 formatter, 判断哪些柱子是 0 或者 1

懂了，谢谢，我还有个小疑问，能否在tooltip的自定义悬浮窗函数formatter中获取一些全局的数据变量？

只能获取它提供给你的参数。
