SCIExtendedLineCreationModifier

@interface SCIExtendedLineCreationModifier : SCIAnnotationCreationModifierBase

Two-pan gesture modifier that creates a SCIExtendedLineAnnotation on a SciChart surface. After completion the modifier resets and is ready to draw another ExtendedLine immediately.

SCIExtendedLineCreationModifier *mod = [SCIExtendedLineCreationModifier new]; [surface.chartModifiers add:mod];

Declaration

Objective-C

@property (nonatomic, strong) SCIPenStyle *_Nonnull stroke;

Swift

var stroke: SCIPenStyle { get set }

extendEnd
- Determine how the line annotation is extended beyond its start/end points.
  
  extendStart = YES, extendEnd = YES → Equivalent to “ExtendBoth” The line is extended in both directions.
  
  extendStart = NO, extendEnd = YES → Equivalent to “ExtendForward” The line is extended only forward from the end point.
  
  extendStart = YES, extendEnd = NO → Equivalent to “ExtendBackward” The line is extended only backward from the start point.
  
  extendStart = NO, extendEnd = NO → Equivalent to “Line” No extension; the line is drawn only between the two anchor points.
