How to change orientation of each item in a ggplot2 legend?

Question

The above shows 2 legends, one where each item is placed in a new column and one where each item is placed in a new row.

How can I control for that?

Do you mean you want two legends in two different directions? Perhaps a simple reproducible example would be helpful here. — Allan Cameron, Feb 07 '22 at 13:26
Can you show us the code that produces the two different legends in a single plot? They normally _do_ go in the same direction, so some data and code that reproduces the problem would be helpful here — Allan Cameron, Feb 07 '22 at 13:28

This is controlled by the nrow and ncol arguments to guide_legend().

You can call guide_legend() either within guides():

plot + 
  guides(color = guide_legend(nrow = 1))

…or within scale_*():

plot +
  scale_color_discrete(guide = guide_legend(nrow = 1))
