[rrd-users] Re[2]: Re: Base for AREA plots

[Sergey Velikanov [UzPAK]]

I think again, and add new CDEF and new AREA operators, now it works
fine!  see http://vgray.uzpak.uz/test.png again, and you don't need to
patch rrdtool

rrdtool graph /home/httpd/www/user1/httpdocs/test.png --imgformat PNG \

"CDEF:value2=value,0,LE,value,0,IF " \
