What is a double bar graph?

A double bar graph shows two sets of data for the same categories, with a pair of bars for each category in two colours and a key that says which colour is which. It makes it easy to compare the two sets category by category.

How do I make a double bar graph?

Enter your categories down the first column, then the first set of numbers and the second set in the next two columns. Name each set in the column header; those names become the key. Or paste three columns from a spreadsheet with a header row.

Can I compare more than two groups?

Yes. Add up to six series. Past four or five bars per group, the colours get hard to tell apart, so consider a stacked bar if the parts add up to a total.

Pasted data

First column: the labels. Each further column is a series (more than one makes a double or stacked bar graph). Copy cells straight from Excel or Google Sheets, or paste CSV. A header row names the series. You can also paste into any cell of the table.

How to make a double bar graph

Put your categories (months, sports, questions) down the first column.
Put the first set of numbers in the next column and the second set beside it. Name each set in its column header: “2025” and “2026”, or “Class A” and “Class B”. Those names become the key.
Add axis titles, check the notes under the graph, and download or print.

Pasting from a spreadsheet? Copy three columns with a header row and paste them anywhere in the table. The header row names the series.

Reading a double bar graph

Compare within a pair to see which set is bigger in each category, and across pairs of the same colour to see how one set changes from category to category. The caption under the graph does the first comparison for you, for example “2026 is higher in 4 of 6, 2025 in 2.”

Keep the colours in the same order in every pair (this maker always does). If the two sets are the parts of one total, like boys and girls in each class, a stacked bar chart shows the totals as well.
