ggplot with two y-axis in R?
问题 I have asked this question earlier but someone close it indicating that it has answer. I am pretty confuse how i can get the two variables plotted on two Y-axis . I want to plot Level on the left y-axis and Flow on the right y-axis (ie., secondary axis). Here is my data and i would appreciate a response. library(tidyverse) library(lubridate) set.seed(1500) FakeData <- data.frame(Date = seq(as.Date("2020-01-01"), to = as.Date("2020-01-31"), by = "days"), Level = runif(31, 0, 30), Flow = runif
