two overlapping fan charts?

[PTillmann-436]

Dear all,

I am plotting impulse respons functions. I want to plot the mean response (beta) and two alternative confidence bands:

graph(nodates,number=0,ovcount=2,overlay=fan,ovsame) 5
# beta / 5
# upper1 / 8
# lower1 / 8
# upper2 / 8
# lower2 / 8

In this graph, one pair is shown as a fan chart, the other as lines. How can I generate two overlapping fan charts?

Thanks for the help.
Peter

The problem with that is that fan charts "paint" an entire region, so if you could do two separate ones (you can't) the second one done will paint over the first. If you one set is reliably inside the other, you can just list the four and the inner one will be colored in a darker shade than the outer one.
