Yes, that's nice, I agree. > Btw, there is a weird thing for large matrices with my obs. as > used below.

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. Allin
