[rrd-users] Re: color tones

I tried to make that also, what I got was this
http://haas.oezie.org/rrd/haas-day-proces.png, from green to red. the
problem now is that I can't graph negative numbers. her is a piece of
perl code I made:

@color = ('00FF00','11FF00','22FF00','33FF00','44FF00','55F F00','66FF00','77FF00','88FF00','99FF00','AAFF00', 'BBFF00',
'CCFF00','DDFF00','EEFF00','FFFF00','FFEE00','FFDD 00','FFCC00','FFBB00','FFAA00','FF9900','FF8800',
'FF7700','FF6600','FF5500','FF4400','FF3300','FF22 00','FF1100','FF0000');

$letter = 'a';
for($i=0;$i<@color;$i++){
$control = ($i+1)*($Size/@color);
$fac = $Size/@color;
$value = $i*($Size/@color);
# print "CDEF:$letter=totaal,$control,GE,$fac,totaal,$valu e,-,0,LE,UNKN,totaal,$value,-,IF,IF\n";
push(@data,"CDEF:$letter=totaal,$control,GE,$fac,t otaal,$value,-,0,LE,UNKN,totaal,$value,-,IF,IF");
$letter++;
}
$letter = 'a';
push(@data,"AREA:$letter#$color[0]");
$letter++;
for($i=1;$i<@color;$i++){
push(@data,"STACK:$letter#$color[$i]");
$letter++;
}

where total is the DEF that you are graphing.

push(@data,"DEF:totaal=$file:hrStorageUsed:AVERAGE ");

maybe this will help you as a start.
