What happened

A rolling axis.x.window named its own clock with now, and calling it did not produce a finite number. The window fell back to Date.now(), so a replay pane is measured against the wall clock and its recorded readings will look too old to draw.

The fix

Return epoch milliseconds from now - () => replay.clock where replay.clock is a number, not a Date, a string or undefined.

The smallest fix

createChart({ grid, container, axis: { x: { window: { kind: 'time', span: 300000, now: () => replayClockMs } } } });
