Histogram Maker
Paste comma or whitespace separated numbers to calculate histogram bins in your browser.
A QUICK WALKTHROUGH
How to use this tool
- Paste finite numeric data separated by commas or whitespace.
- Choose a bin rule, count mode, and optional mean or median marker.
- Copy the bins CSV or download the SVG chart.
Bin rules
Choose Sturges, Scott, Rice, square-root, Freedman–Diaconis, or an explicit bin count. Rules are bounded to keep the chart usable.
Data limits and edge cases
Enter finite numbers only, with at most 10,000 values. At least two distinct values are needed; zero standard deviation or zero IQR receives a clear message.
Privacy
Data stays in this browser. SVG labels are escaped before export.
