export default {
  data() {
    return {};
  },
  mounted() {
    this.polyLineChart();
  },
  methods: {
    polyLineChart() {
      var myChart = this.$echarts.init(
        document.getElementById("polyLineChart")
      );
      var option = {
        xAxis: {
          type: "category",
          data: ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"]
