Nice catch! Although the offender was “Populate compiled directories” rather than “Debugging”.

How does #:skip-paths in compile-directory-zos work? I’ve tried various combinations of absolute and relative paths, and using the info procedure without success:

where unbound-id.rkt is: #lang racket/base plop

I have updated the plot package to allow specifying picts as the labels for various renderers — this will allow using arbitrary images instead of just text — this was done because there were at least two requests of using LaTeX notation as the labels, and this can now be done using the latex-pict package. Here is the pull request, if anyone wants to have a look and provide feedback, I will leave it open for about a week before merging it: https://github.com/racket/plot/pull/64

@alexharsanyi I ask of ignorance: Is there way to place a label (pict) on a given (x,y) coordinate on the plot itself?

There are five: point-pict, parametric-pict, function-pict, polar-pict and inverse-pict. Normally these attach a “label” to a point, but you can use #:anchor 'center and #:point-sym 'none to have the picture centered around the specified coordinates

Great!
