I want to join several graphs in one plot, but something is wrong with my code, cause R makes only one strange looking graph. Can anybody help?
#Make multiple line plot
ggplot(aes(x = Visit, y = LH_concentration, color = Patient, group = 3)) +
theme_minimal() + ggtitle("Concentration over time") +
scale_color_manual(values = c("red", "blue", "green"))
