Frequently asked questions
Is this scatter plot maker free?
Yes — completely free, no account or signup required.
How do I add more data points?
Click the Add Row button in the data table to insert additional X/Y pairs.
What is the regression line?
The regression line shows the best linear fit through your data points, calculated using the least-squares method. Toggle it on or off.
Can I customise colours?
Yes — use the colour picker to set the point colour. Each data point uses the same colour for a clean look.
What format does the download use?
The chart downloads as a PNG image at the canvas resolution. For print quality, the canvas renders at a generous size.
Does my data get sent to a server?
No. All chart rendering uses Chart.js running locally in your browser. Your data never leaves your tab.
