echarts实现象形柱状图（三角锥形柱状图）

象形柱状图效果如下：

option = {
   grid: {
     top: 30,
     bottom: 20
   },
   // 双横坐标轴
   xAxis: [{
    type: 'category',
    data: ['6/10', '6/11', '6/12', '6/13', '6/14', '6/15', '6/16'],
    axisTick: {
      show: false
    },
    axisLine: {
      show: true,
      lineStyle: {
        color: '#E5E6EB'
      }
    },
    axisLabel: {
      color: '#86909C',
      fontFamily: 'font-family: AlibabaPuHuiTi_3_65_Medium',
      fontSize: 11
    },
    splitLine: {
      show: true,
      lineStyle: {
        color: '#EFF0F3',
        type: 'dashed',
      }
    },
  }, {
    type: 'category',
    data: ['周一', '周二', '周三', '周四', '周五', '周六', '周日'],
    axisTick: {
      show: false
    },
    axisLine: {
      show: true,
      lineStyle: {
        color: '#E5E6EB'
      }
    },

      fontSize: 11
    },
    splitLine: {
      show: true,
      lineStyle: {
        color: '#EFF0F3',
        type: 'dashed',
      }
    },
  }],
  yAxis: {
    type: 'value',
    position: 'right', // 右侧显示纵坐标轴
    minInterval: 1, // 刻度最小间隔1
    max: (value) => value.max + value.max*0.1, 
    axisLine: {

    },
    splitNumber: 10
  },
