You _are_ dividing all values above 20000 by 10. But it seems to me you want to divide only the portion above 20000 by 10 and add this to 20000. 1: Why ? 2: that requires a more complex formula. > So 30000 would be displayed as 21000. Is this even possible? Sure. if (x>20000) then return (x-20000)/10+20000 else return x and then transform this into RPN. -- Alex van den Bogaerdt http://www.vandenbogaerdt.nl/rrdtool/ _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
