Hello, I have a problem with ggplot and colors I used this function to draw somes lines and I want them to be all black (just to test) however, I dont get any black line in the figure.
Do you have any experience with ggplot and manual colors??
ggplot(cmax, aes(cmax[,3], cmax[,6],colour=interaction(cmax[,1],cmax[,2])))
+ geom_line() + geom_point() + scale_fill_manual(values=c("black",
"black" , "black", "black", "black", "black", "black", "black", "black",
"black", "black", "black" ))
best regards
