How to Use the Box Plot Maker

Enter your numerical data in the text area above, with values separated by commas, spaces, or newlines. You can also paste CSV or spreadsheet data — the tool will automatically detect the columns and let you choose which one to plot. Click "Generate Box Plot" to create the visualization. The interactive chart lets you hover over any part of the box plot to see exact values, zoom in on specific regions, and pan across the data. Use the camera icon in the chart toolbar to download your box plot as a PNG image. Non-numeric values are ignored.

What Is a Box Plot?

A box plot (also called a box-and-whisker plot) is a standardized way to display the distribution of data. The box spans from Q1 to Q3 (the interquartile range), with a line at the median. The whiskers extend to the furthest data points within 1.5 times the interquartile range. Points beyond the whiskers are shown as outliers. This visualization makes it easy to see the center, spread, skewness, and unusual values in your data at a glance.
