How to color multiple metabolites in KEGG pathways using ggkegg?

[WANGchuang715]

I am using the ggkegg package to draw KEGG pathway maps for metabolites and want to mark multiple sets of data on the same metabolite node, similar to the functionality in the pathview package. In pathview, it is possible to represent multiple sets of data changes using multiple semicircles or sectors. However, in ggkegg, it seems that geom_node_point cannot achieve a similar function.

Hi, thanks for using the package and for reporting the issue. I apologize for the late response. By using geom_node_rect or geom_node_rect_multi, you can map the data in multiple columns using multiple sectors (example). For multiple semicircles, I think we can use geom_scatterpie from scatterpie package (or using some custom shapes in geom_node_point). I’ll prepare some code snippets for that.
