SectorAnnotation

SectorAnnotation📘 draws a radial sector-style annotation. It is useful for marking angular ranges or highlighted circular regions.

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

sciChartSurface.annotations.add(
    new SectorAnnotation({
        isEditable: true,
        points: [
            { x: 2, y: 3 },
            { x: 7, y: 8 },
            { x: 8, y: 2 }
        ],
        strokeThickness: 2,
        fillOpacity: 0.25,
        thresholds: [0, 1],
        regionColors: [ "#38BDF8" ],
        selectionBoxStroke: "none"
    })
);
