To give our bar blocks a black outline we’ve set color to black. Here, aggdata_tsfm is our dataframe, x axis has countries, y axis has percent change in mobility values and we will fill stacked bar chart with our different place categories. By default, ggplot2 bar charts order the bars in the following orders: Factor variables are ordered by factor levels. I am using the same dataset and the same code; the only difference is the version of my R installation and ggplot2---so I am assuming that is the problem here. It provides a reproducible example with code for each type. Here, aggdata_tsfm is our dataframe, x axis has countries, y axis has percent change in mobility values and we will fill stacked bar chart with our different place categories. You could set position to dodge to create side by side bar chart. To illustrate this let’s create an example dataset. The percentage value perc is a value between 0 and 1, but is displayed like a proper percentage by passing it to the percentage function from the scales library.
