Creating a Bar Graph in Google Sheets

Google Sheets is a free and powerful tool that makes it easy to make a bar chart in just a few clicks. Whether you need a vertical bar graph (also called a column chart) or a horizontal bar graph, here’s how to do both.

Example Data

To start building your bar graph in Google Sheets, it helps to have a simple set of example data. For instance, imagine you’re tracking the number of books read by a group of friends over a month. You could have one column for each friend’s name and another for the number of books they completed. Using a small, manageable dataset like this allows you to easily see how Google Sheets translates raw numbers into a visual chart, and it provides a foundation for experimenting with labels, colors, and formatting.

The following data is used for creating a bar graph in Google Sheets in the sub-sections that follow.

Creating a Vertical Bar Graph (Column Chart) in Google Sheets

A vertical bar graph, often called a column chart, is a popular way to display data that compares categories along a vertical axis. Each category is represented by a column, with the height corresponding to its value. This format is particularly effective for showing growth, differences between groups, or trends over time. By starting with organized data, you can quickly create a column chart that highlights your key insights and makes it easier for others to understand your results.

Follow the steps below to make a vertical bar graph in Google Sheets.

1. Enter your data in two columns. For example, column A might list categories, and column B their corresponding values.
2. Highlight the entire data range.
3. Go to the Insert menu and select Chart.
4. In the Chart Editor panel, under the Setup tab, choose Column chart from the Chart type dropdown.
5. Customize your chart in the Customize tab for axis titles, colors, and labels.

The following image shows the vertical bar graph created in Google Sheets from the above steps. This method is ideal if you’re using a free bar graph maker like Google Sheets to create polished, shareable visuals.

Creating a Horizontal Bar Graph in Google Sheets

Horizontal bar graphs provide an alternative to the traditional vertical layout, placing categories along the vertical axis and values along the horizontal axis. This approach is useful when category labels are long or when you want to emphasize the comparison of values rather than trends over time. By flipping the axes, you often improve readability and create a visually balanced chart that communicates the data effectively to your audience.

Follow the steps below to make a horizontal bar graph in Google Sheets.

1. Follow the same initial steps: enter and highlight your data.
2. After selecting Insert > Chart, go to the Chart Editor.
3. Under Chart type, choose Bar chart (not column chart).
4. Customize appearance as needed.

The following image shows a horizontal bar graph created in Google Sheets by following the above steps. This is a great way to make a bar graph online free without installing any software.

How to Create a Double Bar Graph in Google Sheets

Double bar graphs, also known as grouped bar charts, are ideal for comparing two sets of data side by side within each category. This type of graph is particularly useful when analyzing changes over time or differences between two groups, as it clearly shows both sets of values without cluttering the chart. In this section, we explore how to create a double bar graph in Google Sheets, ensuring your data comparisons are visually meaningful and easy to interpret.

A double bar graph lets you compare two sets of data side-by-side across the same categories. Here’s how to create a double bar chart using Google Spreadsheet bar graph tools:

Example Data

Imagine you want to compare monthly sales for two different products. Your data might include a column for the month, a column for Product A sales, and a column for Product B sales. With this simple structure, Google Sheets can generate a double bar graph that places both products’ sales side by side for each month, allowing for immediate visual comparison and analysis.

The following data is used for creating a double bar graph in Google Sheets below. It is a set of data that contains a students midterm score and final score. As a result, each data column is used in a double bar chart for each student.

To create the double bar graph:

• Column A: Categories (Students)
• Column B: First series (Midterm)
• Column C: Second series (Final)

Select all three columns when creating the chart to ensure both bars show up per category.

Step-by-Step Guide

To build a double bar graph, first select your data range, then insert a chart and choose the “Column chart” option. After that, adjust the settings to group the bars by category rather than stacking them. Customizing colors for each data set and adding clear axis labels further enhances the graph’s readability, ensuring that your comparisons are both accurate and visually appealing. Steps for Google Sheets follow below.

1. Enter your data with three columns:
   • Column A: Category labels
   • Column B: First data series
   • Column C: Second data series
2. Highlight all three columns.
3. Go to Insert > Chart.
4. In the Chart Editor, choose Column chart.
5. Under the Customize tab, go to Series to assign colors or tweak settings for each data series.

Google Sheets automatically generates a double bar graph by grouping bars for each category. It’s a simple way to make your own bar graph that shows comparisons clearly.

Tips for Graphing Creating a Bar Graph

Creating an effective bar graph requires more than just plotting numbers. Choosing the right scale, labeling your axes clearly, and selecting appropriate colors can make a huge difference in how your data is perceived. Additionally, paying attention to spacing, gridlines, and legends helps ensure that your graph communicates the intended information quickly and effectively.

Simple tweaks, like highlighting key data points or using consistent color schemes, can make your bar graph more engaging and easier to interpret. Thoughtful presentation not only enhances understanding but also adds a professional touch to your reports or presentations.

• Keep category labels short for readability.
• Use consistent colors or color-coding to group related data.
• Use a horizontal bar graph if category labels are too long.
• Always label axes clearly and include units where applicable.
• Sort data in ascending or descending order for better comparisons.

Did You Know About Creating a Bar Graph?

Bar graphs have a fascinating history that stretches back to the 18th century. They were first used as a tool to simplify complex data, allowing people to quickly grasp numerical differences without wading through tables of numbers.
