这段代码中，x变量和z1数组的长度不一致，应该改为x0数组。另外，xAxis的type应该为category，而不是time。正确的代码如下：

plot2() {
  const limit2 = this.tableData.length;
  let y0 = [];
  let x0 = [];
  for (let i = 0; i <= limit2 - 1; i++) {
    y0.push(parseFloat(this.tableData[i].flux));
    x0.push(this.tableData[i].date);
  }
  console.log(y0);
  console.log(x0);
  let z1 = [];
  for (let i = 0; i < x0.length; i++) {
    z1.push([x0[i], y0[i]]);
  }
  const myChart2 = echarts.init(document.getElementById('chart2'));
  const option2 = {
    title: {
      text: '涌水量-时间'
    },
    tooltip: {
      trigger: 'axis',
      axisPointer: {
        type: 'cross'
      }
    },
    yAxis: {
      type: 'value',
      name: '涌水量'
    },
    xAxis: {
      type: 'category',
      data: x0,
      name: '时间'
    },
    series: [{
      data: z1,
      type: 'line',
      name: '涌水量',
      yAxisIndex: 0
    }]
  };
  myChart2.setOption(option2);
}
