How to use it
- The first column is X (for example ad spend), the second is Y (for example inquiries).
- An optional third text column groups points, such as channel or product line, in different colours.
- Turn on the trend line to see the equation and R² for the linear relationship.
Data format example

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.
What does R² mean?
R² is the share of the variation explained by the straight line, between 0 and 1; the closer to 1, the tighter the points sit around the line. It measures linear association, not cause and effect.
