[rrd-users] Duplicate Y-axis labels Not: Duplicate month

  I imagine you're referring to the   -Y  rrdtool graph argument,
which I have tried previously (and again just now).  It works well in
many situations, but in others, it will print only 1 Y-axis value at a
certain location on the Y-axis (at the middle of the Y-axis in my most
recent test case) which, while eliminating the duplication issue,
introduces another.  Clearly this is the lesser of the evils, but I'll
keep tinkering I guess.
