[rrd-users] Min-min and min-max?

Is there any way to set upper and lower limits for the upper and lower limits?
For example, I'm graphing temperatures from an automated weather station.  The
graph changes its upper and lower limit depending on what needs to be graphed,
which is fine, but I'd like the bottom of the graph to never be higher than
zero, but go as low as it needs to go to show temperatures below zero.
Basically, when the temperature is in the 70's, I don't want my graph to only
show 40-80 degrees.  I want it to show 0-80 degrees.

Is this kind of granularity possible?  Or can I only set main upper and lower
