推荐答案

Google 图表工具中的新功能还没有分别进入 GWT 可视化 API 和包装器.
我实际上不确定 GWT API 是否会更新.但是，您始终可以自己实现这些功能.

Well the new features in the google charting tools haven't made their way into the the GWT visualization API and wrapper respectively.
I am actually not sure if the GWT API's will be updated at all. However you can always implement these features yourself.

根据您创建 DataTable 的方式(以编程方式或通过后端)，您可以:

Depending on how you create your DataTable (Programmatically or by the backend) you can:

• 以编程方式:您可以扩展 DataTable 或 AbstractDataTable 类并通过 JSNI(即addColumn(type, role)等.查看AbstractDataTable).
• 来自后端的 JSON:您可以在后端创建适当的 DataTable JSON 结构，然后调用 DataTable.create() 并将其传递给 draw() 方法，无需任何代码修改.(我还没有测试过，但它应该可以工作，因为 DataTable 只是一个 JavaScriptObject)

• Programmatically: you could extend the DataTable or AbstractDataTable class and implement the missing features and functions via JSNI (i.e. addColumn(type, role), etc. Checkout the source code for AbstractDataTable).
• JSON from the backend: you could just create the appropriate DataTable JSON structure on the backend and then just call DataTable.create() and pass it to the draw() method without any code modifications. (I haven't tested it but it should work as DataTable is just a JavaScriptObject)

顺便说一句:GWT 可视化 API 的最新版本实际上是 (1.1.2)

BTW: the latest version of the GWT Visualization API is actually (1.1.2)
