javascript - Google Visualization - 尝试格式化每个工具提示以通过格式化程序或查询显示百分比

转载作者：行者123 更新时间：2023-12-03 05:41:31

我一直在尝试将图表的工具提示格式化为百分比，但没有成功。以下是将我的项目的以下功能简化为最低限度:

UI 由 2 组单选按钮和 1 个复选标记组成。
用户可以切换查看不同图表类型显示的数据源。
从用户可以查看的 7 个 Google 表格中查询来源。
用户可以使用 4 种图表类型查看这些数据源。
初始数据源由 chartWrapper() 显示(chart 由 drawChart() 调用)
接下来的 6 个数据源共享一个 chartWrapper()(main 由 alterChart() 调用)

我已在 M.C.V.E 中发表评论。 3次失败尝试详情如下:

第一次尝试:将编码的查询字符串添加到数据源网址。
第二次尝试:使用setQuery()
第三次尝试:使用 formatter 对象。

欢迎使用前面提到的 3 种方法中的任何一种来解决此问题。我对我没有涵盖的任何内容都持开放态度，但我可能需要更多详细信息，因为我仍在学习这个 API。感谢您抽出宝贵的时间，我很感激。

最佳答案

您正在设置图表的数据源 URL，并且在您有机会设置数据格式之前它已自行呈现。解决方案是自己查询数据，格式化，然后将其传递到图表中。
