我有一个带 JSON 的动态 Google lineChart 和 3 个静态 Google gaugeCharts...我想将它们全部放在一个 html 页面上。在问这个问题之前，我确实在寻找答案；例如，我认为我没有任何同名变量。所有这些图表都有效。 lineChart 可以完全工作(在一个单独的 html 文件中)，3 个 gaugeCharts 也可以工作(也可以单独在一个 html 文档中)。老实说，我很迷茫，似乎无法让我的工作图表和谐地显示在一起。你能帮忙解决这个问题吗？如您所见，我添加了所有 css html javascript jquery 和 JSON 代码。但问题只是在某处的 html 文件中。

最佳答案

我不认为你可以在同一个函数中调用它们。要么为每个图表创建不同的函数，要么构建所有图表的函数堆栈。 For Reference
