You could use the combination of "--upper-limit 4 --rigid" to always stop graphing at 4.00 You could also choose to use the CDEF approach where you modify the values as described by Serge. This has a "side effect" (not really) of also modifying the values used for GPRINT et al. You are interested in signalling huge peaks. You could setup an AREA with a value of INF and plot this in a color depending on the actual value. This looks like a colored background. Something to start: DEF:load=.... CDEF:background1=load,4,GT,INF,UNKN,IF CDEF:background2=load,10,GT,INF,UNKN,IF .... AREA:background1#00CC00 AREA:background2#FF0000 LINE:load#0000FF:load HTH -- __________________________________________________________________ / [EMAIL PROTECTED] [EMAIL PROTECTED] \ | work private | | My employer is capable of speaking therefore I speak only for myself | +----------------------------------------------------------------------+ | Technical questions sent directly to me will be nuked.
