Bottom legend in multiple rows

[Diogo Ferrari]

Hi eveyone,

I want to plot a legend at the bottom of the graphic. There are 7 categories. I want to plot the legend in two or more columns at the bottom. 

Does enyone have any idea how can I do that. Using  guides(col = guide_legend(nrow = 8))  didn't work, and the legend appears in a single row.

Thank you some much in advance.

We really need some code and data to get an idea of what you are doing.
