I've just re-read or read more carefully the earlier posts about the new band plotting feature. They all seem to talk about a center/width combination to be passed to gretl. This would imply that the bands are restricted to be symmetric -- OK, I admit that you could reverse-engineer fake "center" and "width" values if you have the lower and upper bounds of the band in the first place. But (confidence) bands are not symmetric in general. So I would vote for the possibility to specify arbitrary center/low/high triplets instead. Or am I missing something with this new feature?

OK, so when this gets documented (or is it already, apart from mailing list posts?) and before the syntax is extended there should be a sentence about this reverse engineering. Perhaps it could go in the "cheat sheet" section.

OK, this is unrelated to the asymmetry question of this thread, but still has to do with the band option.
