The pie chart will be drawn in the counterclockwise motion, alphabetically. Donut chart. See this basic example to see how to proceed. The pie() function takes a Frequency table as input. Polar coordinates are also used to create some other circular charts (like bullseye charts). Adding the percentage labels takes a bit of work here but it is manageable. The ggplot2 package allows to build donut charts.Note however that this is possible thanks a hack, since no specific function has been created for this kind of chart. The total degrees of pie chart are 360 degrees. All you need for a pie chart is a series of data representing counts or proportions, together with the corresponding labels. pie <- ggplot(df, aes(x Get Better Insights From Your Graphs With Less Effort! We first create a data frame containing the values that we want to display in the pie chart. I'm going to assume that means the y-axis being expressed in percentage.
