A connected scatter plot places each observation as a dot on standard X-Y axes and then draws a path in chronological order between them. The result is a trajectory: the viewer can simultaneously see how two variables relate to each other and how that relationship evolves through time. Loops in the path indicate periods where both variables retraced previous values; sharp turns indicate inflection points where one variable changed direction while the other did not.

The canonical example is the Phillips curve, which traces unemployment on the X-axis against inflation on the Y-axis year by year. During the 1960s the path ran smoothly along a downward slope; in the 1970s stagflation broke that pattern, and the path looped into high-inflation, high-unemployment territory. No static scatter or line chart communicates that story as directly.

Source & accuracy

This connected scatter is an editorial illustration built to represent the concept accurately. Where it shows figures, they are typical or representative values chosen to make the relationship clear, not a single underlying dataset. The diagram and its explainer are reviewed and maintained centrally, and updated over time as understanding improves.

Trajectories through the X-Y plane over time

A connected scatter plot shows a path of points connected by line segments, with each point's position encoding two variables (x and y) and the sequence showing time or another ordering. The line reveals how the two variables move together: if both increase, the path trends upper-right; if one rises while the other falls, the path trends diagonally. This diagram is useful for visualizing system dynamics, economic cycles (plotting unemployment vs inflation over quarters), or personal data (plotting daily activity vs sleep quality over weeks).

Comparative advantage and reversals

Connected scatter plots reveal cycles, trend reversals, and Pareto frontiers. If you plot multiple entities as separate paths (e.g., different countries), you can see which entities are improving on both dimensions and which are in tradeoff. The diagram also highlights unusual transitions: a sharp right angle or backwards movement signals a regime change. Connected scatter is especially useful in competitive analysis when you want to show how multiple players move through the same capability space over time.
