Hi to all, I need some help for the following task
I have two table called Users and Documents, each user can upload or not several documents I need to create a bar chart with a bar containing the number of users who uploaded less than 10 documents, another bar with the number of users who upload more than 10 documents but less than 100 and the last containing the number of users who upload more than 100 documents.
I've tried with the class function but it seems that the interval cannot be specified for each single bar.
Can someone give me a little hint to complete this chart.
