const { width, height } = calcTooltipSize(valuesWithLabels);
// this calculates and sets svgAnnotation.xCoordShift and svgAnnotation.yCoordShift. Do not set x1 or y1 at this point.

The PolarCursorModifier provides tooltip and cursor behavior on a 2D SciChartPolarSurface within SciChart - High Performance JavaScript Charts
To apply the PolarCursorModifier to a SciChartPolarSurface and add tooltip behavior, use the following code:
const sciChartSurface: SciChartPolarSurface; sciChartSurface.chartModifiers.add(new PolarCursorModifier());📚 Docs: https://www.scichart.com/documentation/js/v4/2d-charts/chart-modifier-api/polar-modifiers/polar-cursor-modifier/
