SCIFibonacciRetracementCreationModifier

@interface SCIFibonacciRetracementCreationModifier
    : SCIMultiPointAnnotationPlacementModifier

Two-point gesture modifier that creates a SCIFibonacciRetracementAnnotation on a SciChart surface. Style properties set here are applied to each annotation as it is created.

SCIFibonacciRetracementCreationModifier *mod = [SCIFibonacciRetracementCreationModifier new]; mod.fillOpacity = 0.2; [surface.chartModifiers add:mod];
