[rrd-users] How to change graph colour as Temperature increases

[Matt.Garrett at shell.com]

Folks

 

I am monitoring some Temperature props.

At the moment graph looks nice with multi AREA stack but what I would
really like is to see the graphs change color

e.g. Temperature range is 0 - 100

Green stack of 0 - 30

Orange stack  30 - 50

Dark Orange 50 -70

Dark Red 70 - 100

 

Current graphs statement looks like

 

$def[1] =  "DEF:var1=$rrdfile:$DS[1]:AVERAGE " ;

$def[1] .= "CDEF:sp1=var1,100,/,12,* " ;

$def[1] .= "CDEF:sp2=var1,100,/,30,* " ;

$def[1] .= "CDEF:sp3=var1,100,/,50,* " ;

$def[1] .= "CDEF:sp4=var1,100,/,70,* " ;

$def[1] .= "AREA:var1#FF5C00:\"Ambient Zone\" " ;

$def[1] .= "AREA:sp4#FF7C00: " ;

$def[1] .= "AREA:sp3#FF9C00: " ;

$def[1] .= "AREA:sp2#FFBC00: " ;

$def[1] .= "AREA:sp1#FFDC00: " ;

$def[1] .= "LINE1:var1#000000:\"\" " ;

$def[1] .= "GPRINT:var1:LAST:\"%3.4lg %s$UNIT[1] LAST \" ";

$def[1] .= "GPRINT:var1:MAX:\"%3.4lg %s$UNIT[1] MAX \" ";

$def[1] .= "GPRINT:var1:AVERAGE:\"%3.4lg %s$UNIT[1] AVERAGE \" ";

 

What I think I need are some form of IF statements to change the color
over a certain value.

Does anybody have any examples they could share.

 

Thanks

 

Matt
