Hi,
I may have nit been clear enough. You could use th eif solution, but:
1. The subplot wit the legend is reshaped
2. The legend is formatted to the size of that particular subplot. So
it doesn't look like a global legend.

What I am trying to do is a more low level solution. So create a axes
that covers the whole figure, plot there, create a legend
(northouside, horizontal) and then try to make the big axes invisible,
so one sees only the legend. The do all the subplots. I could mak
ethis work.

The other option I was exploring is to create a second figure with a
legend and then "copy" the legend to the figure with the subplots.
Though there is a delete method for graphical objects, I can't figure
out how to do a "add" method. that is change the parents and the
childs of the legend.

Hope this makes it more clear
