What is a Double Bar Graph?

A double bar graph, also called double bar chart, is a type of bar graph that displays two sets of data as pairs of bars.

When to use a Double Bar Graph?

A double bar graph is used to compare two datasets when they have the same set of items or categories. Here are some examples:

1. Comparing the total sales of your branches for two consecutive years
2. Comparing the values of KPIs you calculate for two different marketing channels

How to create a Double Bar Graph in Google Sheets

Step 1: Select the range of data that you want to visualize.

Step 2: Click Insert on the main menu 

Step 3: Click Chart.

Step 4: Find the Chart editor, located on the right side of the screen.

The selected chart type is not a double bar graph by default, so we have to change the chart type.

Step 5: Click the drop-down box below the Chart type. 

Step 6: Click the option for Bar chart from the dropdown list that appears. 

Voila!  We now have a bar chart. To add a title to the chart, go to the Customize tab in the Chart editor, then click Chart axis & titles. Make sure that the drop-down box displays the option Chart title. On the text box below the drop-down box, type the title of the chart. 

Here are some more options for modifying the title of the chart: 

• To change the font of the title, click the drop-down box below the label Title font. There are 12 fonts to choose from such as Arial, Georgia, and Verdana. 
• To change the size of the title, click the drop-down box below the label Title font size. You can select from a range from 10 to 36. You can specify a value beyond the given options. You can also choose Auto to let Google Sheets adjust the font size fit for the given chart.
• To center align the title, go to Title format and click the Alignment option. Then click the Center option. 

We now have the following chart!
