Data selection

Select chart observations without changing the source data. This feature belongs to @revolist/charts and can be used without Pivot or a grid.

Try it live

Click a data mark, then inspect the selected targets below. This example uses multiple selection. Click again to toggle, or choose Clear selection.

Selection uses stable row/column members and measure identity. It is different from the drawing toolbar’s Select pointer, which edits annotation shapes.

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.

import { lineChart } from '@revolist/charts/line';
import { groupedColumnChart } from '@revolist/charts/grouped-column';
import { columnLineChart } from '@revolist/charts/column-line';

// When the host unmounts:
// chart.destroy();

API and configuration

await chart.update({ interaction: {
  mode: 'select', selectionMode: 'multiple',
} });
const stop = chart.subscribe(model => console.log(model.selection));
await chart.clearSelection();
// You can also await chart.setSelection(validSemanticTargets).
// Later: stop();

Support and behavior

The type and backend must support select interaction. Standalone Charts maintains local selection; Pivot’s drill and grid-filter adapters are separate. A local selection does not change source rows or a remote query. Saved models include committed selection.

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.
