How do I make the legend category colors bigger so that it is easy to identify what the colors correspond to in the graph.
Following is how I got the plot
ggplot(data=dur)
+geom_line(mapping=aes(x=yr,y=Country,color=dur$elec..sys,size=1.1))

Thanks. This worked ggplot(data=dur)+geom_line(mapping=aes(x=yr,y=Country,color=dur$elec..sys,size=1.1))+guides(colour = guide_legend(override.aes = list(size=3))) – Nathgun Nov 02 '17 at 16:54
