GWT visualization API Motion Chart language

I'm using the gwt visualization library to display motion charts in a gwt app. However, the language shown in the chart is random (different language every time it loads).

This: http://code.google.com/apis/visualization/documentation/using_overview.html#localization says I can set it, but only through the load method. But the GWT load method does not allow me to set anything other than the version and Packages.

As far as I can tell, there is no way of explicitly setting the language using the GWT API.

Any ideas开发者_开发百科?

You can set the locale of a GWT application in many ways: Locales in GWT. My guess would be that the Visualization API uses that value to set its own locale value.

You should be able to do a quick test of this by appending locale=fr (change to your desired locale) to the address:

http://www.example.com/MyGwtApp.html?locale=fr

This will force that locale to be used by GWT.

Update: the AjaxLoader does support setting the language via the AjaxLoader.AjaxLoaderOptions:

AjaxLoaderOptions options = AjaxLoaderOptions.newInstance();
options.setLanguage("fr");
AjaxLoader.loadApi("visualization", "1", null, options);

I'm not sure you can use null for the callback parameter, but you get the general idea.

I've discovered that this is a bug, which I've submitted here:
