in fact, the range of data is between 70 and 100. Why is this happening?

Mar.07,2021

axisLabel: {
    formatter: function (val) {
        return val * 2; //  y 2
    }
},

first delete the label formatter in the yAxis axis, in addition, the maximum value of the Y axis can be determined by traversing the array, do not write dead 110, or directly set to 'dataMax' to automatically get the maximum value.
