常量 { createSampledDataGenerator } = 要求（'@arction/xydata'）
大家好，我正在尝试让这个 ECG（https://www.arction.com/lightningchart-js-interactive-examples/edit/lcjs-example-0150-ecg.html）在没有 nodejs 或 nmp 的情况下工作。我已经看到可以使用 IIFE js 版本。在网站上实现 IIFE 版本时，我发现运行上述命令时出错，我无法在我的网络服务器中执行。我该如何运行它？是否有 xydata 的 IIFE 版本？我必须包含什么脚本以及如何包含？谢谢
xydata可以使用.iife.jsxydata 构建版本直接在浏览器中运行。您可以@arction/xydata从 npm 下载软件包并xydata.iife.js从那里使用该文件，或者您也可以使用像UNPKG这样的 CDN 。
在您的 html 头中添加（如果您在本地提供文件，请<script src="https://unpkg.com/@arction/xydata@1.2.1/dist/xydata.iife.js">替换 src url），然后将. iife 文件会将变量添加到全局上下文中。require("@arction/xydata")xydataxydata
请参阅下面的完整工作示例。我确实必须减少示例中的数据量才能适合此处的示例，因为 StackOverflow 限制了答案的长度。
