Navigator

Adjust the visible X window using a full-domain overview. This feature belongs to @revolist/charts and can be used without Pivot or a grid.

Try it live

Drag either navigator handle to change the window, or drag the band to move it. Plot gestures and the navigator stay synchronized. Reset restores the full view.

The navigator is independent of plot-gesture opt-in: navigator: true can be used without enabling wheel/pan gestures. In this example both are enabled.

The chart uses the native Charts renderer. Buttons outside the plot are example application controls calling the public API.

Complete chart setup with sample data

Install Charts using the installation guide, then run this setup after the host mounts. The data is illustrative. Additional actions for this tool are explained below.

API and configuration

await chart.update({ navigation: { enabled: true, navigator: true } });
await chart.update({ viewport: {
  x: { scale: 'time', min: Date.UTC(2026, 3, 1), max: Date.UTC(2026, 8, 1) },
} });

Support and behavior

Requires a native navigation-capable type with a supported X scale. Numeric XY navigators adjust X and retain the current Y window. Async sources can supply separate overview data; that overview never replaces detail data used for tooltips or exports.

State and cleanup

Authored settings are available through chart.model. Updates replace whole settings objects: spread fields you want to retain, and await the returned promise before reading state or exporting. Destroy the controller when its host unmounts.
