echarts折线图大白点

先看效果图：

 代码如下：

 <div id="lineChart" style="100%;height:100%"></div>

//自适应字体大小变化
 WidthAdaptive(res) {
      var windth = window.innerWidth;
      let fontSize = windth / 5280;
      return fontSize * res;
 },

myecharts() {
      let myChart = this.$echarts.init(document.getElementById("lineChart"));


      // 绘制图表
      //myChart.setOption({
      var option = {
        grid: {
