So the legend shows all the right values, but the graph itself doesn't show anything ? A couple of ideas : 1) try substituting fixed numbers, eg CDEF:usedpct2neg=0,usedpct2,*,50,- CDEF:availpct2neg=0,availpct2,*,50,- 2) try a different formula, eg CDEF:usedpct2neg=usedpct2,-1,* CDEF:availpct2neg=availpct2,-1,* See if either make a difference. Hmm, takes another look and consults the docs ... But before doing that, you may want to take a look at your Y axis scaling options : -l 0 -u 100 -r Which as I read it, means scale from 0 to 100, rigidly. So the Y axis won't extend to negative numbers. Changing to -l -100 ought to fix it. -- Simon Hobson Visit http://www.magpiesnestpublishing.co.uk/ for books by acclaimed author Gladys Hobson.
