#2I note with interest the article links to:
https://ferd.ca/awk-in-20-minutes.html
Very succinct quickstart guide.

#3I want to use gnuplot more, but I generally find myself spending too much time messing with the plot styles to get something I sort of like.
Can anyone point to some pretty styles they've come across?

#4There is no need to initialize variables with -v. You could just do:
awk '/Time/{printf("%d %s ", ++j, $3)} ...Re: Basic Scripting with Awk and Gnuplot

Xkcd style perhaps? https://github.com/rfonseca/xkcd-gnuplot

Some problems: the colours are not that great, and also not colourblind-safe. And most grating of all: why are the tics light gray and not black! It's very hard to read.

#8Beware when piping awk | gnuplot or especially awk | awk: when printing numbers, awk by default prints them with something like %.6g, which can lose important amounts of precision. There are two ways this can happen. Firstly when numbers are implicitly converted to strings, eg for concatenation; and secondly when they are printed directly. These conversations are controlled by two different variables which may be set to printf directives to get higher precision.

#9There is no need to initialize variables with -v. You could just do: awk '/Time/{printf("%d %s ", ++j, $3)} ...
Or use a begin block:
'BEGIN { j = 1 }
/Time/ …
'
I find it best to restrict the use -v to injecting environment variables into my awk scripts.

Just curious but why go for gnuplot (and awk) rather than python or R? At some point you run up to some limit where you want a bit more capability. I don't know that the learning curve is that much less for awk + gnuplot?
