How to use it
- One column of values per group (headers are group names), or two columns — group and value — one record per row.
- The box holds the middle 50 % of values, the line is the median and dots beyond the whiskers are outliers.
- When comparing supplier lead times or batch measurements, look at the box's level (typical value) and length (consistency).
Data format example
Copying from a spreadsheet gives this format, with tabs between columns:
Supplier Lead time Supplier A 18 Supplier A 21 Supplier B 28
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 do I read a box plot?
The line inside the box is the median, the box edges are the first and third quartiles (the middle 50 % of values), whiskers reach the furthest value within 1.5 × the IQR, and dots beyond are outliers. A shorter box means steadier, more consistent data.
How should the data be laid out?
Either works: one column per group (headers are the group names, such as Supplier A and Supplier B), or two columns with the group name and the value on each row, which suits exports from other systems.
