Workspaces and comparisons

One widget can hold several charts. Each chart keeps its own data, analysis and lifecycle, while the widget handles the layout and keeps the charts in sync.

widget.onChartReady(() => {
  widget.setLayout('2h');
  widget.chart(1).setSymbol('MSFT');
});

SynchronizationCopy Anchor Link

Use the built-in controls to sync symbol, interval, crosshair, time and date range across charts. Don't copy every event from one chart to another by hand, because that can cause loops. When you switch to a smaller layout, hidden charts may be kept around. Changing the grid doesn't necessarily clear their state.

ComparisonsCopy Anchor Link

Comparison series belong to their chart. If your release offers the public comparison API, use it, and keep comparisons, indicators and the main series separate. Get fresh handles after restoring a layout.

Sharing drawingsCopy Anchor Link

Which drawings are shared depends on symbol and layout ownership. Sharing keeps drawing IDs stable and checks saved metadata. Don't copy internal model objects from one chart to another.
