Yes, that's nice, I agree.
Glad you like it ;-)

Not really so weird. The number that (can) follow "border" in this
context is a line-type. Line type -1 is a solid black line. So with
"border -1" and the daily djclose data you're requesting that each of
the 2528 boxes is bordered by a black line. That produces a totally
dense black mass with no pixels left to show any colors.
Line type -2 doesn't exist, so (by courtesy, it seems) if you say
"border -2" that's equivalent to saying "noborder", in which case
the
selected colors for the boxes are visible.
Thank you for this clarification. Then
it makes sense to check the
number of boxes and set the option for border accordingly.
Best,
Artur
