How to set axisPointer snap to both X-axis and Y-axis?

Currently, I set yAxis.minInterval = 1. When I attempt to move my mouse inside the graph, can I force the Y-axis line (horizontal line) of the axisPointer to move discretely from 1 to 2, 2 to 3, etc., rather than continuously from 1 to 2 (i.e. 1.00 1.01 1.02 ... 1.99 2)?

如何让axisPointer同时吸附X轴和Y轴？比如我设了y轴的最小刻度为1，我能不能让axisPointer的那根y轴的线不要连续移动，而是只会比如 1 2 3的这样移动?

Expected Behavior

axisPointer snap to both X-axis and Y-axis.

axisPointer同时吸附X轴和Y轴。

Current Behavior

axisPointer only snaps to X-Axis.

axisPointer只吸附在X轴上。

Online Example

tooltip: {
    trigger: 'axis',
    axisPointer: {
        type: 'cross',
        label: {
            backgroundColor: '#6a7985'
        },
        snap: true
    }
},

@cuijian-dexter 不是可能我没表达清楚我的意思是比如我设了y轴的最小刻度为1，我能不能让axisPointer的那根y轴的线不要连续移动，而是只会比如 1 2 3的这样移动

Currently, in an axis whose type is 'value', the axisPointer can only snap to data point, rather than axis tick.

Could I know why do you intend to make axisPointer snap to axis tick (e.g., 1, 2, 3)? If the scenario is reasonable, it can be added as a new feature ~

I'm making a ranking chart. And since the ranking could only be an integer, there's no reason that the y-axis label of the axisPointer would be a floating number rather than an integer. That is what I am thinking. @100pah
