Hello Daniel, First of all many thanks for the reply. I managed to display the chart, by apparently changing only the source for jquery.
There is a twist though : I can only display the chart when accessing the website from outside the localhost. All happened today since I only worked on the localhost until now. The twist is that when I try to access the site in the localhost's browser i get the "Invalid data table format:must have at least 2 columns" error. It works from let's say "external" but it doesn't work internally. I have to say that I am bit baffled by this fact. Any advice or thought regarding what leads to the error mentioned above when opening the web page in the localhoost's browser ? I don't know what information would be viable in diagnosing this issue so please let me know if possible if certain data is needed. The platform on which i have the web server (Apache) is a Raspberry PI2 with Debian Jessie as operating system. > -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
