This is why it doesn't make sense to use a log-scaled y axis with a bar chart. The "variable" column keeps tracks of the original columns. How to plot multiple columns in R for the same X-Axis Value. Creating the cumulative sum manually works. Bar plots are often used to display frequencies of factor (categorical) variables. Here's a quick demonstration of the trick you need to use to convince R and ggplot to do it. The first series (bottom column) is Q1 and the border and area properties are set to none so that the column is not visible in the chart. An individual ggplot object contains multiple pieces – axes, plot panel(s), titles, legends –, and their layout is defined and enforced via the gtable package, itself built around the lower-level grid package. They are also not friendly for colorblind viewers. Create a Two-dimensional Bar Chart.
