I have a question related to embedding a Chart gadget on Google Spreadsheets. Where do I go for help?
For specific questions related to Google Spreadsheets we suggest you first check the Spreadsheet Integration section. You can also refer to the help pages for Google Spreadsheets. If you are not able to find an answer in either of these places, the best way is to post your question on the Visualization discussion group. Google employees also participate in the group and pop in from time to time to answer developer questions.
