Stacked Barplots with ggplot2 in R Stacked Barplot Side By Side with position=”dodge” Barplots stacked vertically are often harder to interpret, as it is harder to make comparison with one main group to another. Elle nécessite l’apprentissage d’un “mini-langage” supplémentaire, mais permet la construction de graphiques complexes de manière efficace. The following code shows how to create the barplot with multiple variables using the geom_bar() function to create the bars and the ‘dodge’ argument to specify that the bars within each group should “dodge” each other and be displayed side by side. Ggplot group by two variables geom_bar. i. e., using geom_bar (values in the data) instead of geom_col (number of cases in each group) Learn how to create a useful and attractive barplot using ggplot.
