Line · Linked time window

Both views use the same UTC instants and retain independent Y scales.

Use lines for change over time or another ordered dimension. Keep missing observations as gaps so the chart does not invent continuity.

Each observation has a seriesId and pointId. Ordered x positions and projected geometry belong to the calculation Core; NativeChart consumes the resulting NativeScene.

Choose series colours, titles, axes, grid and legend placement. Floating tooltips are the default; crosshair and docked details are optional.
