Note: For that case another option would be to remove the axis titles for only the top two plots. With a legend it gets probably more fiddling. Note: That works nice if there is no legend. Adapting my answer on R ggplot2 patchwork common axis labels to your case(s): It provides direct supports to sf and stars objects, meaning that no transformation of those objects is necessary prior to creating maps. In the meanwhile one option would be to stick with patchwork and get some support from cowplot. These geom () s allow for visualizing both vector and raster data through consistent and simple ggplot2 syntax. Hopefully patchwork will gain this feature in one of the next releases.

plot_list Īlthough there are alternative solutions ( ggplot: how to add common x and y labels to a grid of plots) I am trying to stay with using patchwork. We’ve defined the colours on a pixel by pixel basis. Here I attempt to add a second global X-axis title so that each column receives its own x-axis title but all rows share the same axis title. First we add the map data using geomraster(), which is defined by an x and y coordinated, with colours defined by a fill value. I'll want to replace these with fewer axis titles. This is my 'starting' plot: it has a 2x2 layout with axis titles for each cell. Does anyone know how I can add the global x-axes close to the rest of the plot without shifting the y-axis substantially toward the top of the figure? 1. In the following reproducible examples, I show my starting point, successful creation of one global axis, and then (starting at Step 3) my failed attempts to add more alongside what I expected to produce. My issue is that my attempt at creating a global X-axis title places it far away from the other plots and shifts the Y-axis title so it is not centered in the plot. Although this post shows how to create a global Y axis title, it does not show how to create do so for both the X and Y axes.

A global axis title is one that replaces the multiple axis titles along some margin of the plot with a single title, a shown in Step 2 to Step 4 below. But for our own benefit (and hopefully yours) we decided to post the most useful bits of code. Up until now, we’ve kept these key tidbits on a local PDF. # In orer to have a landscape DinA4 format, multiply the width by 1.414286.I am trying to create a global/spanning Y-axis title and a global/spanning X-axis title for a plot containing several ggplot objects arranged in a grid with clockwork. The ggplot2 library is a phenomenal tool for creating graphics in R but even after many years of near-daily use we still need to refer to our Cheat Sheet.

# Install package from githubĭevtools::install_github('MBalthasar/MapBooklet') The second function uses this fishnet polygon in combination with a user ggplot for the creation of a map booklet, including an overview map (see above), as well as a submap for each tile (see below). The package contains currently two functions, one of which creates a fishnet polygon from the extent of the user input data. This R package was designed by EAGLE student Marius Philipp for the automatized generation of map booklet pdfs for user defined ggplots.
