Hi Andy
Thanks so much for your quick response but I had read through the threads
and had already checked to see if it was a stacked linear chart. It was not.
I resolved the issue but probably not in the best way. When I clicked to
edit the Y axis, I saw that the maximum field was set to 1.2 so I just
uncheched that field and changed the value to 1.0 and it seemed to work.
