I don't think this (180) will ever work.  AFAIK rrdtool
does not create unequal parts on any axis.

You may get lucky with multiples of 15 and 17, and --height 255 or
--height 256, but don't hold your breath.  You'll need --y-grid 15:17
or something alike (see man rrdgraph).  --y-grid 51:5 may also be
something to try.  

Using --rigid and --upper-limit is probably necessary as well.
