When it comes to data visualization, flashy graphs can be fun. Believe me, I'm as big a fan of flashy graphs as anybody. But if you're trying to convey information, especially to a broad audience, flashy isn't always the way to go. Whether it's the line graph, scatter plot, or bar chart the subject of this guide!, choosing a well-understood and common graph style is usually the way to go for

It provides several reproducible examples with explanation and R code. Basic barplot with ggplot2. This post explains how to draw barplots with R and ggplot2, using the geom_bar function. It starts with the most basic example and describes a few possible customizations. See how this can be used to make bar charts with variable width

Ordered Bar Chart. Ordered Bar Chart is a Bar Chart that is ordered by the Y axis variable. Just sorting the dataframe by the variable of interest isn't enough to order the bar chart. In order for the bar chart to retain the order of the rows, the X axis variable i.e. the categories has to be converted into a factor.

Sample data sets When you want to create a bar plot in ggplot2 you might have two different types of data sets when a variable represents the categories and other the count for each category and when you have all the occurrences of a categorical variable, so you want to count how many occurrences exist for each group.In this tutorial we will show you how to deal with both types of data.

Stacked Bar Graph. If your data contains several groups of categories, you can display the data in a bar graph in one of two ways. You can decide to show the bars in groups grouped bars or you can choose to have them stacked stacked bars. Suppose, our earlier survey of 190 individuals involved 100 men and 90 women with the following result

For the first example, you'll need to filter the dataset so only product A is shown. The reason is simple - ggplot2 uses stacked bar charts by default, and there are two products in the stack for each quarter. You'll learn how to add labels for multiple stacks later, but let's start with the basics.

There are two types of bar charts geom_bar and geom_col. 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. If you want the heights of the bars to represent values in the data, use geom_col instead. geom_bar uses stat_count by default it counts the number of cases at each x

Barplot of counts. In the R code above, we used the argument stat quotidentityquot to make barplots. Note that, the default value of the argument stat is quotbinquot.In this case, the height of the bar represents the count of cases in each category.

A barplot is useful for visualizing the quantities of different categorical variables.. Sometimes we want to create a barplot that visualizes the quantities of categorical variables that are split into subgroups. For example, we may want to visualize the total popcorn and soda sales for three different sports stadiums.

The default dark grey bars look a bit drab. You can choose a colour and give it as an option to geom_col.If you're like me, you'll probably try a couple of wrong things first either passing the colour inside aes won't work, because the colour will be interpreted as data to plot or using colour instead of fill which changes the border colour instead.
