Usage and data

#

Compare multidimensional patterns across products or observation groups.

Check units and axis directions. Use brushing to focus on a range when there are many lines.

Data contract

PropertyInput format
dataAn array of { id, label?, values: { dimensionId: number } }.
dimensionsEach axis's id, label, domain, and scale.

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.

Add to your interface

#

The code tabs below the preview contain the full data, options, event bindings, and responsive sizing for the current example. Copy them into an app project, such as Vite, that can resolve the installed packages.

Shared sy-chart API versus direct tags
