Hi, I guess once you have "printed" the histogram in a PS file you then visualise it with gv or gs. It is a well know problem that some old versions of gv/gs are not able to visualise patterns. I have just tried your example and visualise the result with: pcitasd29> gs -v Aladdin Ghostscript 5.50 (1998-9-16) Copyright (C) 1998 Aladdin Enterprises, Menlo Park, CA. All rights reserved. and for me it works. By the way, if you print your file on paper it should be fine. Cheers, Olivier -- Org: CERN - European Laboratory for Particle Physics.
