How to specify different graph range

[nemesis]

Default graph range is 24 hour for daily graph (7 days for weekly,
4 weeks for monthly, and 12 months for yearly). How do I change
that to (ie. similar to cricket) 28 hours for daily, 10 days for weekly,
6 weeks for monthly, and 16 months for yearly? I find them easier for
comparing recent and older y-values.

Thank you,
