双y轴折柱图

 设置双y轴

      yAxis: [
          {
            type: "value",
            show: true,
            name: "单位：件",
            axisTick: {
              show: false, //刻度线
            },
            axisLine: {
              show: false, //隐藏y轴
            },
          },
          {
            type: "value",
            name: "单位：%",
            min: -100, //设置右侧y轴显示数据，最大值和最小值
            max: 100,
            splitNumber: 10,
            axisTick: {
              show: false, //刻度线
            },
            axisLine: {
              show: false, //隐藏y轴
            },
            splitLine: {
              show: false, //隐藏y轴横线
            },
          },
        ],

指定使用左边右边Y轴数据，这里折线使用右边y轴

series: [
          {
            name: "本期",
            type: "bar",
            barWidth: 14,
            emphasis: {
              focus: "series",
            },
            data: [220, 182, 191, 234, 290, 220, 182, 191, 234, 290],
          },
          {
            name: "同期",
            type: "bar",
            barWidth: 14,
            emphasis: {
              focus: "series",
            },
            data: [150, -232, 201, 154, 190, 150, 232, 201, 154, 190],
          },
          {
            name: "同比",
            type: "line",
            barGap: 0,
            yAxisIndex: 1,  //指定需要使用的Y轴，1代表右边，0代表左边，默认是左边
            smooth: true,
            symbol: "none",
            emphasis: {
              focus: "series",
            },
            data: [-100, 32, 31, 34, 39, 20, 32, 1, 34, 39],
            lineStyle: {
