Where can I go to get help with using the Chart Tools APIs?
For general questions about the Chart Tools API for GWT, first try the Google Visualization API Google group. Make sure to mention that you are using the GWT wrappers for the project. Another place you can to for help is the GWT-Google-Apis group, which is the forum for the developers of the GWT wrappers for all Google APIs. You can also try the Google-Web-Toolkit group which is the main public forum for GWT.
