How to Make a Bar Chart Online (Free)
Bar charts are the most common chart type for comparing values across categories — sales by region, survey responses, performance metrics. This guide shows you how to create a clean, downloadable bar chart in your browser without any software or account.
When to Use a Bar Chart
- Comparing categories — monthly sales, team scores, product ratings
- Showing rankings — top 10 results, leaderboard data
- Before/after comparisons — two bars per category
- Use a line chart instead for time-series trends over many periods
Step-by-Step Instructions
Open the Bar Chart Maker
Navigate to the Bar Chart Maker. The tool uses Chart.js running locally in your browser — no data is sent anywhere.
Enter your labels and values
The data table shows a Label column and a Value column. Click any cell to edit it. Click Add Row to add a new data point. Click the × on a row to remove it.
Set chart settings
Enter a Chart Title and optional X/Y axis labels. These appear on the rendered chart.
Choose a bar colour
Use the colour picker to set the bar fill colour. For multi-dataset charts, each dataset gets its own colour.

The chart updates in real time as you change data or settings. You can scroll to see the full chart before downloading.

Is My Data Private?
Yes. The Bar Chart Maker uses Chart.js running locally in your browser. Your data values and labels are never transmitted to any server. Closing the tab clears all data.
