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

ggplot(union_current_fraction) +

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.

Thanks,

Newbie Jeff
