Incredibly, I have not been able to find an answer to this question on the web (there are multiple articles and pages but nothing that fits my case, apparently).
I have a graph of the form
ggplot(dataset, aes(x =, y = , label=))+
geom_point(alpha =, color=)+
labs(title=, x = , y = )+
theme_minimal()+
geom_text(size=, hjust=, vjust=)+
xlim()+ylim()
and I would like to merge it with another graph of the same form but with a y referencing a different column in the same dataset.
