Hi, don't know if my first message in this list were seen by anybody, thats why i'm posting again. OWTChart is a great, useful program. But i have problems with the logarithmic scale. The definition of the y-min/max-parameters has no effect in log-scale. Could this be a bug? I'm using: OWTChart V.1.1.0 (20020114) (GDCHART V.2.2.0 (20020111)) Thanks for information, Lutz
