在Vue3项目中使用 Echarts 绘制股票图表的分享（五）：分时图的基础上绘制出五日图

效果展示

分析：五日图其实也就是展示了相当于五天的分时图的数据量；对比前面的分时图绘制效果，我们可以发现：它多出了对这五天内的现价做个最高价和最低价的标注，并且对最新时间段的现价数据做个闪烁点+涟漪特效。

绘制五日图

关键代码

标注数据的最高价和最低价：

options[''series''] = [
    {

markPoint 属性可以对图表的数据进行标注，借由该属性中的 data 字段里面的 type 我们可以在图表上标注出最高价和最低价。

当前时间节点数据的闪烁点：

  options[''series''] = [
  ......
      {
      gridIndex: 0,
      // 设置涟漪特效动画
      type: ''effectScatter'',
      // 有三种: cartesian2d(二维的直角坐标系) polar(极坐标系) geo(地理坐标系) ,此需求使用cartesian2d
      coordinateSystem: ''cartesian2d'',
      // 单个闪烁点 ↓
      data: pricesEffectScatter, //2d坐标系--[x轴, y轴, 标记大小]
      // 何时显示特效:''render''-绘制完成后显示特效 ''emphasis''-高亮（hover）的时候显示特效

现价中的闪烁点是使用带有涟漪特效动画的散点（气泡）图来实现的，它可以利用动画特效可以将某些想要突出的数据进行视觉突出。
