I made a ggplot, including labels above every point of observation. For the points and lines of the chart I manually set colours:
ggplot(data = dfpl2,
aes(x = Jahr, y = Positiv, group = Landtag, col = Landtag))+
geom_point(size=3)+
geom_line()+
scale_colour_manual(values=c("#CC0000", "#0066FF", "#FF0000"))+
geom_label(data = dfpl2,
aes(label = Jahr, fill = factor(Landtag)),
nudge_y=0.25, colour="white", fontface="bold")+
scale_x_continuous(name="Jahr", limits=c(2003,2018)))
How can use those manually chosen colours for the labels? When using the fill command, only the standard colours appear.
