Association and Regression

Start here for relationship-focused figures, from basic scatter views to size-encoded, density-based, and agreement-specific displays.

Overview

  • Use this branch when your figure choice depends on the relationship between variables, a fitted trend, point density, or agreement between two measurements.
  • Read each page for the specific question it answers best, rather than assuming one relationship plot covers every analysis need.

Start here

Use this section when your question is about association, correlation, fitted trends, dense point clouds, or agreement between two measurements.

This branch covers relationship and agreement figures, not distribution-first group comparisons, repeated measurements over time, multivariable clustering structure, or open-ended custom chart design.

If your main question is about distribution shape or group differences, go to Distribution and Group Comparison. If your main question is about many variables at once or clustering, go to Multivariate and Clustering. If your main question is about change over time, go to Time and Longitudinal.
