Implementation
void show(dynamic x, double y, [String coordinateUnit = 'point']) {
// ignore: unnecessary_null_comparison
if (_stateProperties != null) {
final CrosshairBehaviorRenderer crosshairBehaviorRenderer =
_stateProperties.crosshairBehaviorRenderer;
final CrosshairRenderingDetails renderingDetails =
CrosshairHelper.getRenderingDetails(crosshairBehaviorRenderer);
renderingDetails.internalShow(x, y, coordinateUnit);
}
