Re: [Gretl-devel] Gnuplot jitter

Gnuplot 5.2 has introduced the "set jitter" command, which I think could
be quite nice to incorporate in our plot/gnuplot command combo. Just to
show you what the "jitter" thing is about, I prepared a little script,
where we plot log wage versus educational level from the Mroz dataset:
Very nice, I wasn't aware of it.
Comment the "square" option, and you even get a nice swarm-plot.

plot X
option fit=none
literal set jitter spread 0.1 #square
end plot --output=display

I was thinking we could have a --jitter option (possibly with
parameters) to the gnuplot command; I would even think it could be a
good idea to have this on by default is the x-axis series is discrete.
OTOH, one may argue that the same effects is achieved quite easily via a
literal, as in my previous example, and the gnuplot commmand is already
loaded with lots of options and we don't need a new one.
I am in favor of the literal-type of option, as it seems to be more
flexible, e.g. jitter- vs. swarm-like plot.
By the way, is there a simple option to replace the crosses by dots?
"literal set style data point" doesn't work.
