CrossLineAnnotation

CrossLineAnnotation📘 draws a one-point cross-style guide line. It is useful for aligned visual markers across the chart.

It inherits the shared multi-point editing and label behavior from scichart-financial-tools.

sciChartSurface.annotations.add(
    new CrossLineAnnotation({
        isEditable: true,
        points: [{ x: 4, y: 4 }],
        stroke: "#F97316",
        strokeThickness: 2,
    }),
);

tip

CrossLineAnnotation always renders both horizontal and vertical guide lines through the same anchor point, so extendStart and extendEnd are intentionally fixed.
Use strokeDashArray if you want the crosshair to behave like a subtle alignment aid instead of a strong visual anchor.
Because it is still a multi-point annotation, it inherits the same selection and hover behavior as the rest of the trading tools.
