Thanks, @cvanelteren , for your continued development of Proplot into Ultraplot Adding ticks to geographic plots is a practical feature in geoscience studies. Although this feature was requested in Proplot, it was not merged into the codebase, see [Support adding tick marks to geographic plots](https://github.com/proplot-dev/proplot/pull/253) Hopefully, @cvanelteren can add this feature to Ultraplot !
