Hi Ryo,
It seems to be a case of when does Ferret know things as it's
working through a set of expressions and operations. In your
example, change it to an implied range of averaging in X,
yes? set data levitus_climatology
yes? let mt = temp[x=@AVE,y=90S:90N@AVE,z=0:6000@AVE]
yes? let a = {0, 0, 1, 1}
yes? plot/line/symbol/vlimits=-1:4/hlimits=0:5 a*mt
**ERROR: inconsistent sizes of data regions: can't
label X axis of MT
It really should treat these two examples the same, so this is a
bit of a bug -- It's incorrectly deciding it can't resolve the
context in X when combining the X information for variables A
and MT.
