axisPointer: {
      // Use axis to trigger tooltip
      type: 'shadow', // 'shadow' as default; can also be 'line' or 'shadow'
      shadowStyle: {
        // color: 'transparent'
        color: '#f00'
      }
    }

试试在 axisPointer 中添加 shadowStyle 属性

效果

与series添加这个就行了:

  axisPointer: {
    show: false,
  },

option = {
  xAxis: {
    type: 'category',
    data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
  },
  yAxis: {
    type: 'value'
  },
  series: [
    {
      data: [120, 200, 150, 80, 70, 110, 130],
      type: 'bar'
    }
  ]
};
