I am trying to change the line type of a density curve, just so that it stands
out relative to the rest of the density curves that I have on the same plot.
However, the issue is that when I use the "linetype" function to make a dashed
curve (i.e. linetype=2), there is no error, but the actual line type remains
only solid in the generated plot. This is what I tried:
Globalpdf <- ggplot() + geom_density(data=GEV[1:5,], mapping =
aes(x=GLocation45), color="black", size=3) + geom_density(data=GEV[16:20,],
mapping = aes(x=GLocation45), color="black", size=3, linetype=2) +
geom_density(data=GEV[29:33,], mapping = aes(x=GLocation45),
color="blue",size=3) + geom_density(data=GEV[1:5,], mapping =
aes(x=GLocation85), color="black", size=3) + geom_density(data=GEV[16:20,],
mapping = aes(x=GLocation85), color="black", size=3) +
geom_density(data=GEV[29:33,], mapping = aes(x=GLocation85), color="red",
size=3) + geom_density(data=GEV[1:5,], mapping = aes(x=GLocationco),
color="green", size=3) + geom_density(data=GEV[16:20,], mapping =
aes(x=GLocationco), color="green", size=3) + geom_density(data=GEV[29:33,],
mapping = aes(x=GLocationco), color="green", size=3) + xlab("One-day max
(mm/day)") + ggtitle("Global") + xlim(150, 300)+theme(plot.title =
element_text(size=54))+ theme(axis.title=element_text(size=54)) +
theme(axis.text=element_text(size=54)) + theme(panel.background =
element_blank())
Doing this correctly produces the series of pdf curves on the plot, as shown
below, but the second black curve that I specified to appear as "dashed"
remains as a solid black curve, rather than the desired dashed black curve. It
is only that one that I require to appear as dashed. Is there a reason for this
happening?
Any help with this would be greatly appreciated!
Thanks,
