Overlapping Bar Charts in Google Sheets: Step-by-Step Guide

Data visualization is the go-to method when you want quick insights into your data.

But not any type of visualization design can be used in your data storytelling. Some charts are designed to visualize information in an exploratory way. Others are designed to display the composition and comparison of sub-variables contributing to the whole data.

If your goal is to display the composition and comparison of key variables in your data, your go-to chart should be an Overlapping Bar Chart (OBC) in Google Sheets.

Popular and widely used visualization tools, such as Google Sheets, lack ready-made Overlapping Bar Charts.

But you can transform the spreadsheet into a reliable tool by installing third-party add-ons to access visually appealing and ready-to-use Overlapping Bar Chart Google Sheets.

Overlapping Bar Chart in Google Sheets

Definition: An Overlapping Bar chart in Google Sheets is similar to a standard Bar Chart. However, unlike a Stacked Bar Diagram, its composite variables that contribute to the whole, start at the baseline.

The chart is best suited to comparing two distinct variables. An Overlapping Bar Chart in Google Sheets is more useful than a Bar Chart, especially if your goal is to display comparison insights.

The data visualization design requires three data columns or rows from your data set””one for categories, one for the series in each category, and one for values.

Keep reading because, in the coming section, we’ll address the following question: what is a great way to use a Bar Chart showing an overlap?

Overlapping Bar Charts in Google Sheets are a handy tool for comparing various datasets or categories within a single chart. They offer a straightforward way to visualize relationships and trends, making data analysis more accessible.

This chart type shines when we need to emphasize both similarities and differences across different groups of data. By layering bars from distinct datasets, we can quickly spot patterns, correlations, or discrepancies.

Ultimately, this visual aid streamlines the process of interpreting data, empowering better decision-making and insights.

When to Use an Overlapping Bar Chart in Google Sheets?

The Overlapping Bar Chart in Google Sheets is best used to compare different items or categories. Similarly, a Stacked Bar Chart in Google Sheets allows for a visual comparison of multiple numerical variables within each category, providing a clear overview of how each segment contributes to the total. However, the Overlapping Bar Chart can only compare two numerical variables per item or category in your data. The data points should be closely related to merit a comparison.

As you know there is no way to overlay graphs in Excel and Google Sheets so you can use Overlapping Bar Charts to show multiple bars in one bar presenting different variables, Also, you can use the visualization design for trends analysis and patterns over time based on similar premises.

The conceptual idea behind the Overlapping Bar Chart in Google Sheets is to contrast key data points using color-coded overlaps.

How Does an Overlapping Bar Graph in Google Sheets Look Like?

An Overlapping Bar Chart in Google Sheets is a two-dimensional graph with two axes -similar to a standard Bar Chart and Clustered Bar Chart in Google Sheets.

Visualization Source: ChartExpo

Its rectangular bars are oriented horizontally or vertically. One axis depicts categories, while the other shows numerical values related to two variables.

Bars representing the same category share the same baseline. We recommend that the numerical variables be closely related and share the same scale to get reliable insights. If you’re unsure how to make a graph from a table, ensure that your variables are consistently aligned for accurate visualization.

Take a look at the table below.

Can you provide a reliable data story after going through the table?

City	Planned Orders	Completed Orders
New York	100	80
Houston	150	120
Chicago	100	100
Washington	250	180
Boston	80	120
Dallas	300	250
Los Angeles	120	90
Seattle	100	75
Denver	80	25
Portland	300	250

Note the difference after visualizing the data using Overlapping Bar Chart Google Sheets.

Note how easy it is to decode the chart above. For instance, Boston surpassed the target set for orders by 40 units. Chicago achieved its target. Conversely, Portland and Dallas have missed their targets by -50 units.

Insights

• Boston surpassed the target set for orders by 40 units. Chicago achieved its target.
• Conversely, Portland and Dallas have missed their targets by -50 units.

What Makes a Good Data Visualization?

• Consider how figures and backgrounds contrast. The standard rule is to have a gradient in similar shades for online observation.
• Identify accepted thresholds for each variable. Doing so provides a benchmark against past performance. Besides, it can guide you on how to avoid displaying misleading differences between categories, such as those seen in misleading chart examples.
• Label Overlapping Bar Chart, but not to the extent that creates clutter.
• Sort data by value to emphasize scale.
