![]() ![]() Notice that the secondary axis label method could also be used for a top axis label by using scale_x_continuous. , name = "Your label", labels = NULL, breaks = NULL)) Scale_y_continuous(sec.axis = sec_axis(~. Theme(plot.title = element_text(hjust = 0.5, size = 12))įor a right facet axis label put a blank secondary axis. Change the text size to match the rest of the graph. Top facet axisįor a top facet axis label, center a ggplot title. So here are two workarounds to get a secondary axis label on the top or right axis using standard ggplot2. Things were getting complicated without referring to the figure caption. But I had two groups in a 4 x 4 grid with facet arranged on the x and y axis. You might not need a label if you are faceting by one group. “New York, London, Tokyo”, and you’d like a label saying something like “Location” over the names of the cities to indicate what you are faceting by. Say you have faceted a plot into a 1 x 3 grid by names of cities, e.g. However, there is no integrated function in facet_grid() to label the facet group in the margin like a secondary axis. ![]() ![]() There is some flexibility in customizing how graphs are faceted and the aesthetics can be tweaked by calling “strip.” in theme(). I prefer to do all my graph editing in R rather than a vector image software and facet_grid() and its partner facet_wrap() are useful functions for presenting graphs of factors with multiple levels. The graph in question was a faceted plot made using the standard ggplot2 function facet_grid(). I recently had to beautify some figures for a publication. ![]()
