Put points down

Three (x, y) pairs on a scatter plot: x₁–x₃ horizontal, y₁–y₃ vertical. Edit a card and the matching point moves in place.

You can change the numbers right here, but changes made here are not saved. To keep what you build, use “Open in CalcAnyway” and edit there.

Try moving it

Change y₂ from 5 to 1 — only the middle point drops. Follow the lines to see which card owns which point.
Add more x and y cards and connect them — a fourth and fifth point simply appear.
