Usage and data

Explore correlation, clusters, and outliers. Use series to distinguish observation groups.

A visible relationship does not establish causation. Adjust marker size or sample count to inspect overlapping points.

Data contract

Property	Input format
`values`	An array of [x, y] or { x, y }.
`series`	Set values, name, and color for each group.
`xAxis`	Use a linear axis for continuous coordinates.

Updating data

Assign a new array or object to the property instead of mutating values inside an array. Chart events provide selection results through event.detail. When disposing of the view, clean up ResizeObserver and event listeners registered by your app.
