Ethan , I don't think you understood what I was reporting.

None of those examples seems to have anything to do with iteration.

What I was expecting to see was that the substitution done by for [...] 
would be applied to the file name and each file name would be used as 
the default title , as is usually the case without iteration.


having a legend that looks like:

"dataset-".date.".dat"
"dataset-".date.".dat"
"dataset-".date.".dat"
"dataset-".date.".dat"

is certainly of no use , so one is obliged to set it explicitly .

plot for [date in "1881 1883"]  "dataset-".date.".dat" tit 
"dataset-".date.".dat"

No harm done but its a bit messy.
