Idea: make upset axes

[teunbrand]

Essentially a discrete axis as made by {ggupset}, but not tied to a scale or upset logic. Can also be just unconnected points for boolean values or coloured points to overlay some categorical value.

Hi Teun, I just saw this issue and wanted to say that legendry feels like a great place to standardize my approach from ggupset! My mental model for ggupset is that it is just a pretty display of compound axis labels like "Drama", "Drama|Comedy", "Romance", "Drama|Romance" etc..

Taking this one step further, do you think legendry could accommodate completely arbitrary plots as shown here? My naive understanding is that this could be a new type of guide which accepts a function that produces a plot and receives the limits. For axis guides, one would need to ensure that the output is correctly aligned, and for legend guides one would need to think through how to do the layouting.

Hi Constantin!

Yeah an upset axis is a neat graphical ideom to display categorical combinations. I much prefer ggupset over upsetR as it better sticks to ggplot2's grammar :)

In a way, legendry::gizmo_grob() already supports arbitrary grobs, which can be plots via ggplot2::ggplotGrob(). But perhaps a more specialised guide function including aligning the limits could be put to better use. I'll open a separate issue for this!

Sounds great :)
