如何在 google 分析中包含依赖项

How to include dependencies in google analytics

我正在尝试在我自己的网站上创建和显示 google 分析的自定义仪表板。我正在关注 ga-dev-tools to achieve this. Problem is i am unable to add components and dependencies including view-selector2.js, date-range-selector.js and active-users.js. I am unable to find these files anywhere on google as well. when i paste the code given on third party visualizations 上的 tuts,上面写着 view-selector2.jsdate-range-selector.js 和在控制台中找不到 active-users.js 文件。 到目前为止,这是我的代码
