      //统计绘画
      drawLine() {
        var echarts = require('echarts');
        // 基于准备好的dom，初始化echarts实例
        let myChart = echarts.init(document.getElementById('myChart'))
        // 绘制图表
        myChart.setOption({
          xAxis: {
            type: 'category',
            name: '日期',
            data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
