Yes you can, but only for a single graph (not multi-graphs like disks). You can't do calculations to adjust the graph COLOR value, but you can draw more than one graph so that one hides the other and gives the impression of changing colours.

Example 1:

[image: Inline images 1]

This is the config I used, based on the standard [la] definition:

[la] TITLE CPU Load YAXIS Load DEF:avg=la.rrd:la:AVERAGE CDEF:la=avg,100,/ CDEF:la_lo=la,0.3,MIN AREA:la#CC0000:CPU Load Average AREA:la_lo#00CC00:CPU Load Average > 0.3 -u 1.0 GPRINT:la:LAST: \: %5.1lf (cur) GPRINT:la:MAX: \: %5.1lf (max) GPRINT:la:MIN: \: %5.1lf (min) GPRINT:la:AVERAGE: \: %5.1lf (avg)\n

What's happening here is that I draw two AREA graphs, the first one showing the normal graph in red, and the second one (which goes in front of the first) with a cap of 0.3 (using "MIN"). So you can see the reds peeking out above the greens.

Example 2:

[image: Inline images 2]

This is the config I used:

[la] TITLE CPU Load YAXIS Load DEF:avg=la.rrd:la:AVERAGE CDEF:la=avg,100,/ CDEF:la_hi=la,0.3,LT,0,la,IF AREA:la#00CC00:CPU Load Average AREA:la_hi#CC0000:CPU Load Average > 0.3 -u 1.0 GPRINT:la:LAST: \: %5.1lf (cur) GPRINT:la:MAX: \: %5.1lf (max) GPRINT:la:MIN: \: %5.1lf (min) GPRINT:la:AVERAGE: \: %5.1lf (avg)\n

What's going on here is that I define a new variable "la_hi" which is set to the value of "la", but is then set to zero if it's less than than the threshold - in other words, untouched only if it equals or exceeds the threshold.

Then I graph the standard "la" graph, and in front of that, I graph the new "la_hi" graph. Where the "la_hi" is zero, you see the "la" graph peeking through.

Is it possible to have a custom graph display different colors based on the value and if so can someone help show how?

For example if the value of the graph is

0-80 then color = yellow

81-100 then color = green

TIA
