Grouped Bar Chart

An upgraded clustered bar chart that's perfect for side-by-side comparisons.

What is a grouped bar chart?

A grouped bar chart displays data using rectangular bars, organizing them into clusters for different categories. Within each cluster, individual bars represent subcategories, often distinguished by color. This visualization allows for side-by-side comparisons of multiple data series across categories and their respective subcategories.

Bar charts excel at comparisons, allowing readers to easily visualize differences between groups.

Distribution dot plots

Graphmatik improves upon classic bar charts by defaulting to an overlay of individual data points and error bars. This helps you avoid misinterpreting identical-looking bars that might represent vastly different distributions. Our hybrid bar plots are designed for both beauty and clarity, allowing viewers to easily discern sample size, outliers, and the underlying shape of the data.

Tips for creating beautiful grouped plots

Sort your clusters
For simpler comparisons and improved clarity, arrange your clustered data in ascending or descending order.

Easily swap directions
Alternate between vertical and horizontal bar charts by toggling between columns or rows.

mean
The sum of a set of values divided by the number of values in the set.
median

standard error of the mean (SEM) mean
How much the sample means vary from the population mean.
standard deviation (SD) mean
A measure of the variation of a set of values around their mean.
95% confidence interval (95% CI) mean or median
95% probability that the population parameter lies within this range.
range mean or median
The difference between the highest and lowest values within a set.
Interquartile range (IQR) median
The middle 50% of a set of values (i.e. 3rd quartile - 1st quartile).
