OK, so assuming those 3: Here a "Red/green" colorcoding you could also use: CDEF:DS1GREEN=DS1,UN,0,1,IF CDEF:DS1RED=DS1,UN,1,0,IF CDEF:DS2GREEN=DS2,UN,0,1,IF CDEF:DS2RED=DS2,UN,1,0,IF CDEF:DS3GREEN=DS3,UN,0,1,IF CDEF:DS3RED=DS3,UN,1,0,IF TICK:DS1GREEN#00ff00:-.03 TICK:DS1RED#ff0000:-.03 TICK:DS2GREEN#00ff00:-.02 TICK:DS2RED#ff0000:-.02 TICK:DS3GREEN#00ff00:-.01 TICK:DS3RED#ff0000:-.01 # here graph the other stuff (on top of the ticks!)
Then you would get 3 stripes that are green/red in the relevant sections of the DS being undefined If you want even "bars" separating those 3 sections: add the following: CDEF:bar=1 TICK:DS1GREEN#00ff00:-.03 TICK:DS1RED#ff0000:-.03 TICK:bar#000000:-0.21 TICK:DS2GREEN#00ff00:-.02 TICK:DS2RED#ff0000:-.02 TICK:bar#000000:-0.11 TICK:DS3GREEN#00ff00:-.01 TICK:DS3RED#ff0000:-.01 that should show bars all the length of the graph with green/red in between I also have sent a patch to Tobi to allow TICK to use the values of the DEF/CDEF itself as the fraction - so this could mean a non-constant fraction... This may also be helpful in some usecases to present data...
