Scatter Plot Maker

A scatter plot displays individual data points on two axes — X and Y — to visualize the relationship between two continuous variables. The direction of the point cloud (upward or downward slope) shows whether the correlation is positive or negative; the tightness of the cloud shows strength. SciFig's scatter plot maker renders a clean point cloud and labels both axes with your variable names.

Specify that you want a linear regression trend line when describing your scatter plot. SciFig's linear regression scatter plot maker overlays the best-fit regression line, optionally adds a 95% confidence band, and annotates the figure with the regression equation and R² value — standard requirements for a linear regression scatter plot in a research paper methods or results section.

A trend line — typically the ordinary least squares (OLS) regression line — shows the best-fit linear relationship between X and Y across all data points. Its slope indicates how much Y changes per unit of X, and R² measures how much of the variance in Y is explained by X. A linear regression scatter plot maker like SciFig overlays this line so readers can assess the relationship at a glance.

A scatter plot shows individual observations as independent points without connecting them — it is used when the X variable is continuous and the relationship between observations is not sequential. A line graph connects points in order — usually used for time-series or sequential data. For showing correlation or regression between two variables in a research study, use a scatter plot maker rather than a line graph.

Yes. A multi-group scatter plot uses distinct colors or point shapes to differentiate subpopulations or experimental conditions. Describe your groups and SciFig's scatter plot maker assigns each a unique marker style and color, adds a legend, and can overlay a separate regression trend line per group — ideal for showing whether a relationship holds across conditions.

Each axis label should include the variable name and unit of measurement — for example, 'Body Mass (kg)' on the X-axis and 'Resting Heart Rate (bpm)' on the Y-axis. Avoid abbreviations unless they are standard in your field. SciFig's scatter plot maker places axis labels at the correct position and font size for journal publication by default.
