Geom_area(aes(color = variable, fill = variable),Īlpha = 0.5, position = position_dodge(0.8)) + Geom_line(aes(color = variable), size = 1) + Gather(key = "variable", value = "value", -date) R function: gather() - Create a grouping variable that with levels = psavert and uempmed library(tidyr) You should first reshape the data using the tidyr package: - Collapse psavert and uempmed values in the same column (new column). Here, we’ll plot the variables psavert and uempmed by dates. Geom_line(aes(size = unemploy/pop), color = "#FC4E07") Ggplot(data = economics, aes(x = date, y = pop)) + Control line size by the value of a continuous variable:.Ggplot(data = ss, aes(x = date, y = pop)) + Ggplot(data = economics, aes(x = date, y = pop))+ Load required packages and set the default theme:.In this section we’ll plot the variables psavert (personal savings rate) and uempmed (number of unemployed in thousands) by date (x-axis). Demo data set: economics time series data sets are used. ![]() Plot types: line plot with dates on x-axis.
