How to use it
- One column of values, one per row, such as order values, lead times or measurements.
- Bins are calculated automatically, or choose 5 to 30 yourself.
- Mean, median, standard deviation, minimum and maximum appear below the chart.
Data format example
Copying from a spreadsheet gives this format, with tabs between columns:
Order value 1200 860 2300
Frequently asked questions
How do I bring in data from Excel?
Select the range including headers in Excel, WPS or Google Sheets, copy and paste it into the data box; tabs are detected automatically, and CSV or comma- or semicolon-separated text works too. Thousands separators, currency symbols and percent signs are removed.
Is there a watermark? Can I put it in PowerPoint?
No watermark. PNG exports at twice the chosen size and SVG is vector, so both stay sharp in PowerPoint, Word or print; you can also copy the image and paste it directly.
Is my data uploaded?
No. Data is parsed and drawn in your browser. A share link carries the data after the # in the URL, which is never sent to the server; only people with the link can see it.
How many bins should a histogram have?
By default the bin width follows Freedman–Diaconis (2 × IQR ÷ cube root of n), falling back to Sturges when values are concentrated, rounded to readable widths such as 1, 2, 2.5 or 5. You can also set the bin count yourself.
How is a histogram different from a bar chart?
A bar chart compares categories; a histogram groups one column of values into ranges with adjacent bars showing how many values fall in each, revealing distribution, skew and outliers.
