Function: createLinkGroup() ​

createLinkGroup(charts?, options?): LinkGroup

Defined in: packages/core/src/link-group.ts:92

Keep the crosshair, visible range, symbol, interval, timezone and (opt-in) drawings of several charts in step.

A chart that follows another is never echoed back: each link compares the new state with what the chart already shows, and only a real change on one chart is passed to the others. A followed range moves the chart like a pan, without animation and without touching its autoscale.

Parameters ​

charts? ​

readonly Chart[] = []

options? ​

Partial<LinkGroupOptions> = {}

Returns ​

LinkGroup

Example ​

ts
const group = createLinkGroup([daily, hourly], { symbol: true });
group.add(weekly);
group.applyOptions({ drawings: true });
group.destroy(); // unlink, the charts stay
