This dataframe union_current_fraction contains these two columns
CC18_308a approval_fraction <fct> <dbl> 1 0.0219 2 0.0391 3 0.0276 4 0.184
I have tried various versions of this
geom_col(aes(x=CC18_308a, y=sum(approval_fraction )))
to no avail. I get four columns but they are all of the same height.
