What I have seen, involves in creating a whole lot of CDEFs lines, that compute a new area that is slightly less than the data you are looking at. For example: .... CDEF:max_in_95=max_in,0.95,* CDEF:max_in_90=max_in,0.90,* CDEF:max_in_85=max_in,0.85,* .... CDEF:max_in_05=max_in,0.05,* ... AREA:max_in_05#rrggbb AREA:max_in_10#rrggbb AREA:max_in_15#rrggbb ... AREA:max_in_95#rrggbb And.. here is the trick... you change the "rrggbb" string slightly to indicate how the color should change. -- EinarI -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://lists.ee.ethz.ch/rrd-users WebAdmin http://lists.ee.ethz.ch/lsg2.cgi
