Please help me on this one…drilling down the x axes on this grpah is really important because of the huge number of data it shows.. Thank you very much 🙂
This is for anyone who will come accross this problem with column charts..it took me 2 days but for some it might be a pretty obvious answer, so here goes, this code adds amcchart scrollbar to a column chart in javascript. 🙂
hope it helps 🙂
