Graphs and charts are powerful tools in Excel for visualizing data and identifying trends. One commonly used type of chart is the double bar graph, which allows you to compare two sets of data side by side.
Whether you’re a beginner or an experienced Excel user, creating a double bar graph can enhance your ability to analyze and present data effectively.
This article will look into the details of how to make a double bar graph in excel, exploring their usage, significance, and considerations for different levels of expertise.
Significance of a Double Bar Graph
A double bar graph is particularly useful when you want to compare two different categories within the same dataset.
For instance, you might use it to show the sales performance of two products over a specific time period, or to compare the performance of two different teams in a competition.
The advantage of a double bar graph is that it provides a clear visual representation of the comparison, making it easier to interpret and draw conclusions from the data.
Step-by-Step Guide: Creating a Double Bar Graph in Excel
Beginner Level:
-
Organize Your Data:
Start by entering your data into an Excel spreadsheet. Create two columns—one for each category you want to compare (e.g., Product A and Product B), and another column for the corresponding values.
-
Select Data:

-
Insert a Chart:
Navigate to the “Insert” tab on the Excel ribbon. Click on “Insert Column or Bar Chart” (the exact icon may vary depending on your version of Excel).
-
Choose a Double Bar Chart:
In the chart options, select the clustered column chart (the first option in the list). Excel will create a basic column chart with your selected data.
-
Customize the Chart:
With the chart selected, click on “Chart Design” in the ribbon to explore various customization options. You can modify the chart title, axes labels, legend, and colors to enhance readability.

Add Data Labels (Optional):
To display the exact values on the bars, right-click on the bars and choose “Add Data Labels.”
-
Final Touches:
Adjust any other formatting or layout elements as needed to make the chart visually appealing and easy to understand.
Expert Level:
-
Use Pivot Tables (Optional):
For complex datasets, consider using a pivot table to summarize and organize your data before creating the chart.
-
Customize Axis Scaling:
Fine-tune the scale of the vertical axis to ensure that the differences between data points are clearly visible.
-
Overlay Additional Data Series:
Enhance the chart by overlaying additional data series, such as trendlines or error bars, to provide deeper insights into the data.
-
Modify Chart Types:
Experiment with combining different chart types (e.g., clustered and stacked columns) to create more advanced visualizations.
-
Utilize Chart Tools:
Explore advanced chart tools and features, such as spark lines, to create dynamic and interactive charts that respond to changes in data.
Conclusion:
In Excel, mastering the creation of a double bar graph opens up a world of possibilities for data analysis and presentation.
