Simple deform modifier is deforming my object. This is the equivalent of making two distinct plots using par(mfrow = c(1,2)). in the output cowplot is removing the background theme, of the both plots ? To make multiple histograms from grouped data, the data must all be in one data frame, with one column containing a categorical variable used for grouping. Learn more about us. Thanks for contributing an answer to Stack Overflow! I wrote grid.arrange() to provide a simple interface as close as possible to par(mfrow). How to Create two side by side plots from a subset of data in R? geom_density() With facets, the axes have the same y scaling in each facet. Facets are helpful for making similar plots for different groups. Your email address will not be published. Here is an example to create multiple histograms with different fill colors: In this example, the geom_histogram() layer is used three times, each with different sample data (data1, data2, and data3).

Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Note that this will only allow the y scales to be free the x scales will still be fixed because the histograms are aligned with respect to that axis: Figure 6.6: Histograms with the default fixed scales (left); With scales = free (right). First well take a look at the factor levels, then well assign new factor level names in the same order, and save this new data set as birthwt_mod: Now when we plot our modified data frame, our desired labels appear (Figure 6.5). Note that we have specified within the grid.arrange function that we would like to combine the plots in two columns. Something like this with bars as continuous without the breaks or border in between. If you specify a particular theme, the default theme doesn't matter. See the answer by @claus-wilke below and this vignette for an equivalent approach; but the function allows finer controls on plot location and size, based on this vignette. Without it, ggplot will stack the histogram bars on top of each other vertically, making it much more difficult to see the distribution of each group. I've got two histograms with different colours, but I don't get a legend or a label which shows which is each colour.

One frequent point of confusion is that the cowplot package changes the default ggplot2 theme. I wrote the cowplot package to solve this (and a few other) issues, specifically the function plot_grid(): The object that plot_grid() returns is another ggplot2 object, and you can save it with ggsave() as usual: Alternatively, you can use the cowplot function save_plot(), which is a thin wrapper around ggsave() that makes it easy to get the correct dimensions for combined plots, e.g. Statology Study is the ultimate online statistics study guide that helps you study and practice all of the core concepts taught in any elementary statistics course and makes your life so much easier as a student.
