Chris,
thanks for helping me out. I considered Option 1 and then dismissed it
for lack of elegance. :-) Option 2 makes sense, not as simple as I had
hoped for, but at least it works.
I still think that the plot title moving as a result of the
axs.yrange=[0,1] command is a bug. I thought we had a similar exchange
a while ago, but I am not entirely sure that this was the same issue.
It may have been on moving x/y titles instead.
Cheers,
Haje
