Many things might be failing. Here are some ideas on things to try: * Check your JavaScript console to see if there is an error message. * Replace the LineChart with a Table chart, just to see if the data looks as you expect. * Use local data, to bypass the ajax fetching. * Could you set up a jsfiddle example so we could be looking at the same code?
