I restored the database and tried it.  It seems that if the time "now"
is reached, it fails.  set '--end now-5h' and then the Y-axis will go
from 60 to 75, or use alt-autoscale for 65.5 to 72.5

Tobi,

It seems that this is a bug introduced in 1.0.4, I assume that when the
unknown value at the end is reached, im->minval is set to zero.
Couldn't find out where, sorry.  I do not have the 1.0.3 and 1.0.4 sources
available so I couldn't diff.

Regards,
