简介： 29-Vue之ECharts-散点图

前言

  • 本篇来学习散点图的实现

散点图特点

  • 散点图可以帮助我们推断出不同维度数据之间的相关性, 比如：看得出身高和体重是正相关, 身
    高越高, 体重越重
  • 散点图也经常用在地图的标注上

散点图实现步骤

  1. ECharts 最基本的代码结构
  2. 准备 x 轴和 y 轴的数据准备 x 轴和 y 轴的数据
  3. 准备配置项

    //1. ECharts最基本的代码结构
    //2. x轴和y轴数据 二维数组 [ [身高,体重],...   ]
    //3. 将type的值设置为scatter, x轴和y轴的type都是value

  • 效果

散点图常见效果

气泡效果

var option = {
  series: [
   {
      type: 'scatter',
      data: axisData,
      symbolSize: 25,
      itemStyle: {
        color: 'green',
     }
   }
 ]
}

涟漪动画效果

  • type:effectScatter：能够产生涟漪动画的效果
  • rippleEffect ：可以配置涟漪动画的大小
  • showEffectOn：以控制漪动画在什么时候产生, 它的可选值有两个: render 和 emphasis
  • render 代表界面渲染完成就开始涟漪动画
  • emphasis 代表鼠标移过某个散点的时候, 该散点开始涟漪动画
var option = {
  series: [
   {
      type: 'effectScatter',   // 产生涟漪动画的效果
      showEffectOn: 'emphasis',  // 鼠标移过某个散点的时候, 该散点开始涟漪动；可选其他值 rende
      rippleEffect:{
        scale:3    // 涟漪动画的大小
     }
   }
 ]
}
