没啥可说的直接粘贴就行
下面放代码

//template
    <ve-line
      width="100%"
      height="300px"
      :data="chartData"
      :settings="chartSettings"
      :data-zoom="dataZoom"
      :loading="loading"
      :extend="chartExtend"
    >
      <div v-if="!loading &&dataEmpty" class="data-empty">没有数据</div>
    </ve-line>

//js
data(){
    this.chartExtend = {
      series: {
        smooth: false
      }
    };
    ...
