Actually what I want to do *is* drawing histograms. What I am looking for is an improved vertical resolution. Compare these figures that all represent the same constant increase: _ _ _-"| ## _ _ _| | | _-" | ##### _ _ _| | | | | | _-" | ######## _ _ _| | | | | | | | | _-"_________| ########### _|_|_|_|_|_|_|_|_|_|_|_| [...+....1..] [...+....1.] [...+....1....+....2...] In the first case I did use '_' to represent values smaller than 1/3, '-' for values between 1/3 and 2/3 and '"' for values above 2/3 (in units of a single character box). As has been pointed out: the issue is large slopes. The scond one uses '#' for anything above 1/2. The last image shows a 'real' histogramm. You see the difference (both in terms of resolution and width)? The playing around with this problem gave rise to a new signature. I'm pretty sure it will result in some 'Your signature is too long' false alerts ;-) Josef 'Jupp' Schugt -- Web: http://jupp.tux.nu/ __..--""""""--..__ jup...@gmx.de _________________________..--"" There's source ""--..______________ ""--..__ out there! __..--"" ""--..__..--""
