Line · UTC dates

Real dates in UTC milliseconds with detail at each instant.

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.
