2 js引入

<script  src="/statics/admin/js/g2.min.js"  language="JavaScript" ></script>

3 copy 示例到代码

报错

浏览器控制台

Uncaught (in promise) ReferenceError: Chart is not defined
    at onlineCount.html:154
//提示引入错误
 const chart = new Chart({
                    container: 'container',
                    autoFit: true,
                    height: 500,
                    padding: [30, 20, 70, 30]
                });

修改后
 const chart = new G2.Chart({
                    container: 'container',
                    autoFit: true,
                    height: 500,
                    padding: [30, 20, 70, 30]
                });

//继续报错
g2.min.js:13117 Uncaught (in promise) TypeError: Cannot read property 'appendChild' of null
    at new e (g2.min.js:13117)
    at onlineCount.html:154
// container 对应id找不到
<!-- 创建图表容器 -->
    <div id="c1"></div>

  const chart = new G2.Chart({
                    container: 'c1',
                    autoFit: true,
                    height: 500,
                    padding: [30, 20, 70, 30]
                });

显示成功
