[rrd-users] Area in different colors

[Simone Felici]

Hi to all!

I know, this was often discussed, but I cannot find an example.
I've a graph with one DS (area) and I need this single DS change color every 20 units if the DS goes over these values. The scale goes from 0 to 100 
(like a rainbow).
I've found something but only changing one time the colour:

(...)
'DEF:cnxs=NbCnx.rrd:cnxs:AVERAGE' \
'CDEF:Cnxs=cnxs,600,LE,cnxs,600,IF' \
'CDEF:CnxsOrange=cnxs,600,LE,0,cnxs,600,-,IF' \
'AREA:Cnxs#00FF00' \
'STACK:CnxsOrange#FF9F00'
(...)

This works, but I've no idea how to create multiple colors...
Can someone help me?
Thank's a lot!

Simon
