If you want the heights of the bars to represent values in the data, use geom_col() instead. I produced the exact-exact same plot with a different version of R and ggplot2 and you can see that the problem persists: r ggplot2 bar-chart . We will take you from a basic stacked bar plot and explain all the customisations we add to the code step-by-step. But this visual can be changed by creating vertical bars for each level of categories, this will help us to read the stacked bar easily as compared to traditional stacked bar plot because people have a habit to read vertical bars. You could set position to dodge to create side by side bar chart. The height of the bar depends on the resulting height of … To put the label in the middle of the bars, we’ll use cumsum(len) - 0.5 * len. Reading time ~1 minute At times it is convenient to draw a frequency bar plot; at times we prefer not the bare frequencies but the proportions or the percentages per category. To put the label in the middle of the bars, we’ll use cumsum(len) - 0.5 * len. Traditionally, the stacked bar plot has multiple bars for each level of categories lying upon each other. Following this tutorial will help you understand how to transform data in R and plot a stacked bar chart.
