Easy Guide: Making a Double Bar Graph in Excel

Creating a double bar graph in Microsoft Excel is an effective way to visually compare two sets of data side by side. This type of chart is particularly useful for presenting data that shows relationships or contrasts between different categories or over time. Here’s a step-by-step guide to creating a double bar graph in Excel that will help you showcase your data with clarity and impact.

Step 1: Prepare Your Data

First, you need to ensure your data is structured correctly. For a double bar graph:

• Data in columns: Your categories should be in one column, while the corresponding data points for each category should be in adjacent columns.
• Clear labels: Label your columns with descriptive titles, which will be used as series names in your graph.

Step 2: Select Your Data

Click and drag to highlight the range of cells containing your data, including labels. Here’s what you need to select:

• Header row for categories.
• The two columns of data you wish to compare.

Step 3: Insert the Double Bar Graph

1. With your data selected, go to the Insert tab on the Excel Ribbon.
2. Under the Charts group, click on the Column or Bar Chart icon.
3. Choose Clustered Bar from the drop-down menu.

📝 Note: The default chart might not be a double bar graph right away. Excel will often create a grouped or stacked chart instead.

Step 4: Modify Chart Type

To create a double bar graph:

1. Click on the chart to select it.
2. Right-click on the chart and choose Change Chart Type…
3. In the Change Chart Type dialog box, select the Combo tab.
4. Under Choose the chart type and axis for your data series:
   • Select your first series of data and set it to Clustered Bar.
   • Select your second series of data and set it to Clustered Bar as well.
   • Make sure both series are set to use the same axis.

Step 5: Format Your Graph

To ensure your double bar graph looks professional and effectively communicates your data:

• Adjust the colors: Use different colors for each series to easily distinguish them.
• Labels and Titles: Add chart title, axis titles, and data labels. You can also change font sizes for better readability.
• Legend Position: Position the legend appropriately. You might consider placing it to the right or below to reduce clutter on the chart itself.
• Axis Customization: Modify scale, gridlines, or spacing if necessary to present your data more effectively.

📝 Note: While formatting, consider what information you want to highlight. A legend might not always be necessary if the bars are clearly labeled.

Step 6: Analyze Your Data

Once your graph is ready, take some time to analyze:

• Are there any unexpected trends or relationships?
• Can you spot any outliers or unusual data points?
• Does the chart tell the story you intended?

Summing Up

By following this guide, you’ve learned how to structure your data, insert and customize a double bar chart, and make it informative and visually appealing. Remember, the power of this visualization tool lies not just in its creation but in its ability to convey complex data in a simple, understandable format, facilitating better decision-making and presentations.
