Currently I know it should be set here

series[ { markpoint:{ data:[] } } ]

But it is not clear what value should be filled in the data.

The official example is like this

data : [ {type : 'max', name: '最大值'}, {type : 'min', name: '最小值'} ]

Bubbles are only used on the maximum and minimum. The effect I want is to display it on each column, and the displayed value is the value corresponding to the y-axis. How should it be set?
