Bar charts are likely the most common chart type out there and come in several varieties. A Bar Graph or a Bar Chart is a graphical display of data using bars of different heights.

Before diving into the ggplot code to create a bar chart in R I first want to briefly explain ggplot and why I think its the best choice for graphing in R. Always start by calling the ggplot function. By default ggplot2 uses the default factor levels and uses that as order for bars in the barplot.

If you want the heights of the bars to represent values in the data use geom_col insteadgeom_bar uses stat_count by default. Coord_flip to create horizontal plots. Top 50 ggplot2 Visualizations – The Master List applies what was learnt in part 1 and 2 to construct other types of ggplots such as bar charts boxplots etc.

In a recent university project I had to collect and analyze data via Google Forms. In the R code above we used the argument stat identity to make barplots. However often you may be interested in ordering the bars in some other specific order.

We can re-order the bars in barplot in two ways. Geom_bar and geom_colgeom_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. The aim of this R tutorial is to describe how to rotate a plot created using R software and ggplot2 package.

To make graphs with ggplot2 the data must be in a data frame and in long as opposed to wide format. If you create a stacked bar chart based on one variable the border will be placed around each bar as there is no other variable involved. And it needs one numeric and one categorical variable.

To make creating the plot easier I will use the bar_chart. This type of graph denotes two aspects in the y-axis. Factor variables are ordered by factor levels.

Finally call geom_bar. Note that the default value of the argument stat is binIn this case the height of the bar represents the count of cases in each category. It has to be a data frame.

Plot value labels along with bars. The first one counts the number of occurrence between groups. This post explains how to build grouped stacked and percent stacked barplots with R and ggplot2.

I often see bar charts where the bars are directly labeled with the value they represent. Ggplot is a package for creating graphs in R but its also a method of thinking about and decomposing complex graphs into logical subunits. Learn how to change the border color the color palette and how to customize the legend.

In this post I will walk you through how you can create such labeled bar charts using ggplot2. It counts the number of cases at. Adjust bar width and spacing add titles and labels.

This short tutorial shows you multiple ways how to do so. You want to do make basic bar or line graphs. Grouped stacked and percent stacked barplot in ggplot2.

The second one shows a summary statistic min max average and so on of a variable in the y-axis. It provides a reproducible example with code for each type. Customizing the Look and Feel is about more advanced customization like manipulating legend annotations multiplots with faceting and custom layouts.
