I think it would be better to have this as function you can apply to your data rather than a new plot type. E.g. scatter(jitter(xs), ys). That could then be reused with lines and other plotting primitives without the need for extra recipes.

[behinger]

could such a function work with AoG?

PS: I made something related with Dodge, e.g. Dodge(Scatter,...) - but the other way round ;)
MakieOrg/AlgebraOfGraphics.jl#393 (comment)

[behinger]

further, jitter would need access to both x & y, x to jitter, y to calculate the kde

[ffreyer]

jitter(xs, ys) and/or jitter(ps) would be fine too

[behinger]

It is still unclear to me how this would work with AoG.jl

[ffreyer]

Sorry this kind of slipped my mind. I don't know how this would integrate with AoG. In Makie this would just be something you'd apply to your input before passing it to a plot function. In that sense it should be pretty similar to smoothing with Loess, which AoG seems to have an implementation for.

[behinger]

ok- then I would have to rewrite it though, to follow the AoG syntax. This is unlikely to happen in the next months, pretty swamped.

Here is an example:

I could also move the whole recipe to AoG

This is implemented in https://github.com/asinghvi17/SwarmMakie.jl as an extra algorithm for beeswarm plots :)

very nice! beautiful :-)
