Very useful article on using gnuplot to plot log data information. I used it yesterday to look at the data on LDAP response rates that I’ve been collecting for a few weeks, and the suggested script (with appropriate minor changes) worked great. On the last line, points may be better than lines, depending on what you’re graphing.

It transpires that the occasional blip in LDAP response rates here isn’t particular time-dependent (although there’s a couple of minor peaks at the two times when I know most people are around and doing stuff), so I need to consider the matter further.
