Hi Mariusz,

Do you have data in the range 7->30 ?

Could you send a short script including your histogram file
that I can use to reproduce the problem?

When sending mails to roottalk, please specify a subject. Mails with no-subject
are in principle deleted by the system as it makes the life hard to people
using the roottalk digest.
