Hello,I got a big problem currently and i really hope that someone here can help me. I am working on some graphs that are integrated into a django app. So far no problem. I had really no experience with matplotlib before but i managed to create 2 of 3 graph types the way our graphics designer wants them to be. The last variation is making me really sick because it has nothing much to do with an ordinary graph (except the fact that is has bars ;)). Please take a look at the attachment and give me a hint how i could realize that. I would really appreciate that. Kind regards, Ben
The attached example (adapted mostly from barchart_demo2.py) should guide you in the right direction.
