You could plot the lines using different patterns of dashes (so that they show up under each other); or use an alpha channel to make them semi-transparent.
If your lines are coloured R G and B and you make them dashed as .-.-.-.-, ..--..-- and ....---- with a 0.5 alpha then you'll get a colourful pattern when they overlap :) Steve Steve Shipway University of Auckland ITS UNIX Systems Design Lead s.ship...@auckland.ac.nz Ph: +64 9 373 7599 ext 86487 ________________________________________ From: rrd-users-bounces+s.shipway=auckland.ac...@lists.oetiker.ch [rrd-users-bounces+s.shipway=auckland.ac...@lists.oetiker.ch] on behalf of Martin T [m4rtn...@gmail.com] Sent: Monday, 9 May 2011 10:40 a.m. To: rrd-users@lists.oetiker.ch Subject: [rrd-users] displaying graphs which often overlap I'm monitoring battery temperatures of three uninterruptible power supplies. All three are usually 35C- very seldom the temperature increases or decreases a degree or two for a short period of time. So as you can imagine, I have three lines overlapped so basically it looks like I'm monitoring only one device. It's not some sort of serious problem or something, but I was just wondering, are there some clever techniques to display/generate graphs in such situations? regards, martin _______________________________________________ rrd-users mailing list rrd-users@lists.oetiker.ch https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users _______________________________________________ rrd-users mailing list rrd-users@lists.oetiker.ch https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
