Re: New plot capability: "bee swarm" plots

[Tait <gnu...@t4...>]

I find the implementation in R to be confusing. There are several
"types" of jitter, which appear to confound jitter in two
dimensions. JMP also offers jitter, if you want another
implementation to look at for a constrasting approach.

Jitter means applying a "small" (definition of which is open to
debate) offset to the specified dimension of a data set. I have
implemented it before within the "... using ..." directive to plot,
and that is where I believe it makes the most sense, e.g.
    plot 'data.dat' using (jitter($1)):2
As used this way, the jitter offsets don't alter the non-jittered
dimension, which the R examples appear to do.

The extension to higher-dimension plots seems straightforward. One
might jitter in x AND y, or in u and t, or jitter the size and/or
color with "ps variable" or "lc variable".
