【数据可视化】—大屏数据可视化展示

一、数据可视化

数据可视化的目的：借助于图形化工具，清晰有效的传达与沟通信息。

数据可视化可以把数据从冰冷的数字转换成图形，揭示蕴含在数据中的规律和道理。

二、免费数据可视化库

Echarts

百度创建的这个库对于 Web 的数据可视化非常有用。它也提供英文版本，适用于大数据集。它还支持 SVG 和 Canvas 渲染。

适用于：所有环境

D3.js、AntV……

三、Echarts使用五步曲

在这里插入图片描述

<style>
        .box{
            width: 500px;
            height: 500px;
            background-color: pink;
        }
    </style>
</head>
<body>
    <div class="box">

    </div>
    <script src="./js//echarts.min.js"></script>
    <script>
        //初始化
        var myChart=echarts.init(document.querySelector(".box"))
 // 指定图表的配置项和数据
 var option = {
        title: {
          text: 'ECharts 入门示例'
        },
        tooltip: {},
        legend: {
          data: ['销量']
        },
        xAxis: {
          data: ['衬衫', '羊毛衫', '雪纺衫', '裤子', '高跟鞋', '袜子']
        },
        yAxis: {},
        series: [
          {
            name: '销量',
            type: 'bar',
            data: [5, 20, 36, 10, 10, 20]
          }
        ]
      };

      // 使用刚才指定的配置项和数据显示图表。
      myChart.setOption(option);

    </script>
