I highly recommend exploring other charts and functionalities ggplot2 has to offer. We need to tell it to put all bar in the panel in single group, so that the percentage are what we expect. geom_bar() makes the height of the bar proportional to the number of cases in each group (or if the weight aesthetic is supplied, the sum of the weights). EDIT: thanks to a suggestion in the comments, the percentages in the plots are different because I used different countries (but the same code and the same dataset). Use geom_col(position = "fill") (Figure 3.20): library (gcookbook) # Load gcookbook for the cabbage_exp data set ggplot (cabbage_exp, aes (x = Date, y = Weight, fill = Cultivar)) + geom_col (position = "fill") Figure 3.20: Proportional stacked bar graph 3.8.3 Discussion.

I want to produce a percent bar plot which looks like this (made in LibreOffice Calc): Thus, the bars should be standarized so all stacks have the same height and sums to 100%. To show the percentage labels within the stacked bar, the geom_label function must have it’s own y aesthetic so they are well alligned. There are lots of ways doing so; let’s look at some ggplot2 ways. Grouped, stacked and percent stacked barplot in ggplot2 This post explains how to build grouped, stacked and percent stacked barplot with R and ggplot2.

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. Converting country_region to factor so that ordering is preserved in our plot. A percent stacked barchart displays the evolution of the proportion of each subgroup. Sorry for not giving you reproducible code, but I believe my problem is just me not updating my code as ggplot2 developed (or maybe is plyr the problem?) Finding it difficult to learn programming? Changing the text size to improve readability. Our ticks will scale from -250 to 100 increasing by 50.

Subgroups are displayed on of top of each other, but data are normalised to make in sort that the sum of every subgroups is 100. If you want the heights of the bars to represent values in the data, use geom_col() instead. I’m going to make a vector of months, a vector of the number of chickens and a vector of the number of eggs. In order to initialise a plot we tell ggplot that charts.data is our data, and specify the variables on each axis. It looks like this: Data. Setting the subtitle and caption of our plot.

This type of plots can be created with the spineplot and mosaicplot functions of the graphics package. It's more useful in the form of a reproducible example, called a reprex.In this case, to answer it it necessary 1) to track down the grid.arrange function (found in the gridExtra package and 2) to guess what data explore_data represents.. Stacked bar plots represent different groups on the top of one another. EDIT: thanks to a suggestion in the comments, the percentages in the plots are different because I used different countries (but the same code and the same dataset). 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.

When producing stacked barplots with percentage labels I would do something like: As today, if I try the exact same code with the exact same dataset, I get the following plot: As you can see the labels are not positioned properly on the bars, and the colors get inverted making the reading of the plot awkward (as if stacked barplots were not awkward enough already). This would be grouped by year and Julian date with the Sex (M/F) stacked. A percent stacked barchart is almost the same as a stacked barchart.
