So, what I think you want to do is to set a maximum upper-limit and a minimum lower-limit but allow autoscaling between this? RRDtool lets you do the opposite (specify a minimum upper limit and maximm lower limit and allow scaling outside) but not this - at least, not directly. What I would suggest is that you use a CDEF on your variable to clip it to the maximum range you want, and then you'll have it. 'var' is your variable. We're limiting it to the 0-100 range. CDEF:newvar=var,0,LT,0,var,IF,dup,100,GT,EXC,100,EXC,IF Now graph newvar. Make use to use 'var' in your VDEFs and not 'newvar', though, else you'll not get the correct calculations.
