...uld like to have a horizontal bar plot of *count* by city and a line plot of weekly average of the variable *z*. I have tried the following: ggplot() + geom_bar(data=dat, aes(x=city, y=count), stat="identity",position="dodge") + coord_flip() + geom_line(data=dat, aes(x=week, y=mean_tmin)) However, this flips the code for both the bar plot and the line plot. I would the y-axis of the line plot to be on the left-vertical axis. I read that it is difficult to have a secondary axis with ggplot. Any help will be highly appreciated. Thank you! dput(dat) structure(list(city = structure(...

Hi Miluji, Using Jim's interpretation of your desired graph, you could do it in ggplot2 using your dat DF by: ggplot() + geom_bar(data=dat, aes(x=week,y=count,fill=city),stat="identity",position="dodge") + coord_flip() + geom_line(data=dat, aes(x=week, y=mean_tmin)) There would still need some work to be done to get the weekly mean into a legend, but it is achievable if required.
