HiI am using Google chart API (with php) in my project to show some chart like line, pie, bar etc.I want to insert a comment next to each data point on a chart that's created, so that this data can store to the database. Eg: I have a trend line for 5 years. The values being 10,13,22,15,14 For one or more of these points, I want to insert a comment in the graph that I create. Eg: The spike in Year3 has been due to blah blah.... How do I do this? Any tweaks? Please help!!!Thanks in advance.
