Quick facts
How it works
From raw points to a regression chart in minutes
Add your data
Enter or paste X and Y values. Name points for clarity and turn on grid lines if helpful.
Example: X = Study Hours, Y = Test Score; points A–E.
Generate with AI
Describe your goal and ask for a linear regression. The AI plots points, fits a line, and shows the equation and R².
“Plot ad spend vs. revenue and fit a linear regression with the equation on the chart.”
Refine the view
Adjust dot size, opacity, stroke, axis labels, and legend position. Toggle point labels, tooltips, and reference lines.
Legend right, labels off, tooltips on, grid lines on.

Who it’s for
Scatter and regression for real‑world decisions
ROI and efficiency trends
Plot ad spend vs. revenue, CAC vs. LTV, or leads vs. close rate. Add a trendline to quantify correlation and forecast.
Experiment analysis
Visualize measurements, calibrations, or survey relationships. Show equation and R² for reports and lab write‑ups.
Risk–return patterns
Map volatility vs. return, cost vs. yield, or factors vs. performance; use regression to indicate expected outcomes.
Performance vs. results
Chart load time vs. conversion, session length vs. retention, or errors vs. satisfaction; track changes over sprints.

FAQ
What is a linear regression graph maker?
It’s a tool that builds a scatter plot and fits a straight trendline to model the relationship between X and Y. This maker adds the line, displays the equation, and reports R² to show fit quality.
How do I create a scatter plot with a regression line here?
Add or paste your X and Y values, then enable the regression trendline. The tool draws the line, calculates the equation, and can label R². You can also ask the AI to generate the chart from a short description.
Can I show the regression equation and R² on the chart?
Yes. Turn on reference lines and select the regression display to reveal the equation and R². Position the legend for a clear mapping and keep labels concise for readability.
Can I customize dot size, opacity, and stroke?
Yes. Use dot size, dot opacity, and stroke width controls to improve clarity, especially with dense clouds. Adjust label font size and grid lines for better legibility.
Where can I place the legend?
Choose top, bottom, left, or right. You can also hide the legend entirely if labels or tooltips provide sufficient context.
