What is a bar chart?
A bar chart compares quantities across distinct categories. The length of each bar represents its value, making large differences, rankings, and outliers easy to see. Bar charts are a dependable choice for survey answers, product sales, department budgets, website traffic sources, and any other categorical dataset.
How to make a bar chart online
- Upload a CSV or Excel file, or open Manual Entry and paste your labels and values.
- Check that the first row contains column names and the first column contains category labels.
- Choose a color palette, enter a descriptive chart title, and decide whether to show the legend and grid.
- Download the finished chart as a high-resolution PNG or scalable SVG.
Bar chart best practices
- Start the numerical axis at zero when bar length is the encoding. A truncated axis can exaggerate small differences.
- Sort bars when ranking is important. Preserve chronological or natural order when the categories already have one.
- Use short, specific labels and avoid unnecessary 3D effects.
- Prefer one strong color, using a contrasting color only when you need to highlight a particular category.
- Switch to a horizontal bar chart when labels are long or there are many categories.
Bar chart or line chart?
Use bars for separate categories such as regions or products. Use a line when the points form a continuous sequence, most often dates, and the change between adjacent points matters. If you need to show how several components contribute to each category total, use a stacked bar chart.
