Hi,
I'm working with a couple of diagrams in excel 2007.

Here's a picture of it so far http://img178.imageshack.us/i/98893112.jpg/

It looks fine, all i need is that the line for temperature reaches the Y axis on both sides, so that january and december are joined. I also need to keep the staple diagram as it is in the background. Is this possible to do?

Would be extremely grateful for any help.

Kind regards,
Björn
