Tom, This is a bug I've reported here in the past - the problem (to me) seems to be that with a *constant* value column, the difference in the high and low is zero, and therefore the scaling "denominator" is going to be zero, if not properly considered in the limit case. Ideally, they'd have a flat line in the graph, but it's not shown at all. I can't tell you what to do in this case, because I too, am wishing this were possible. For now, it's not. Maybe they'll see this and count it as another vote for a fix to this problem. But for now, constant lines and "allmaximize" are not going to work together. Sorry for the bad news.
