That does look nicer - thanks! At the end of the day this will allow me to generate my plots, but it’s a bit inconvenient because my other plots unfortunately don’t work with pgfplotsx() (and they’re slow, so I want to use GR for its promised speed). Simply changing the backend for some of the plots doesn’t work in my code as written, because of this issue where you can’t change plot backends within a function. In any case, I’ll mark this as the solution since the original problem is a known issue with the GR backend.
