IAnnotationPlacementStrategy
StockSharp.Xaml.Charting.StrategyManager
定义允许放置注释的方法的接口
方法
GetBasePoints
public Point[] GetBasePoints(AnnotationCoordinates coordinates)result = iAnnotationPlacementStrategy.GetBasePoints(coordinates)获取注释实例的基准点
- coordinates
IsInBounds
public bool IsInBounds(AnnotationCoordinates coordinates, IAnnotationCanvas annotationCanvas)result = iAnnotationPlacementStrategy.IsInBounds(coordinates, annotationCanvas)检查坐标是否在画布边界内
- coordinates
- annotationCanvas
MoveAnnotationTo
public void MoveAnnotationTo(AnnotationCoordinates coordinates, double horizontalOffset, double verticalOffset, IAnnotationCanvas annotationCanvas)iAnnotationPlacementStrategy.MoveAnnotationTo(coordinates, horizontalOffset, verticalOffset, annotationCanvas)将注释移动到特定的横向和纵向偏移
- coordinates
- horizontalOffset
- verticalOffset
- annotationCanvas
PlaceAnnotation
public void PlaceAnnotation(AnnotationCoordinates coordinates)iAnnotationPlacementStrategy.PlaceAnnotation(coordinates)将注释与特定的注释坐标相连接
- coordinates
SetBasePoint
public void SetBasePoint(Point newPoint, int index)iAnnotationPlacementStrategy.SetBasePoint(newPoint, index)设置注释的基准点
- newPoint
- index
