【WEB前端】使用百度ECharts,绘制项目质量报表

xiaoxiao2021-02-28  186

一、下载ECharts的js库

下载地址:http://echarts.baidu.com/download.html

由于我们对体积无要求,所以我们采用了完整版本,功能齐全,在项目中,我们只需要像普通的 JavaScript 库一样用 script 标签引入即可。

<!DOCTYPE html> <html> < head >      <meta charset= "utf-8" >      <!-- 引入 ECharts 文件 -->      <script src= "echarts.min.js" >< /script > < /head > < /html >

二、绘制项目质量报表

根据需求,我们期望在绘制出如下的报表:

在绘图前我们需要为 ECharts 准备一个具备高宽的 DOM 容器。

<body>      <!-- 为 ECharts 准备一个具备大小(宽高)的 DOM -->      <div id= "echarts-line-chart" style= "width: 600px;height:400px;" ></div> </body>

然后就可以通过 echarts.init 方法初始化一个 echarts 实例并通过 setOption 方法生成一个统计图,下面是完整代码:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127
