You can remove your legend title with labs(color="") since the color aes gives your legend the name:

library(ggplot2) ggplot(data=df, aes(x=df$X, y=df$Y, color=df$Variable))+ geom_line(size=1)+ labs(x = "x", y = "y", color = NULL) + theme_bw() 

Plot: [![your plot without legend name][1]][1]

Also working:

scale_color_discrete(name = NULL)
