Hello, I drew a simple area plot using ggplot2 using
set <- read.table(file="http://www.jovian.nl/set.csv";, head=1, sep=",") library(ggplot2) ggplot() + layer( data = set, mapping = aes(x = time, y = hours), geom = "area", stat="smooth", color="red" ) + layer( data = set, mapping = aes(x = time, y = hours), geom = "area", color="red", fill="red", alpha="0.5" ) I have two questions about this visualisation: - The smooth function is too "rough" right now, how do I make it follow the original values more closely? - The smooth function turns up with negative values (e.g. at the beginning): How do I prevent this? (e.g. to use 0 instead of any negative value.)
