Lo scorrimento di iOS Core-Plot non funziona correttamente

Question

Utilizzo di CorePlot versione 1.6. iOS in esecuzione 8.3.

Sto utilizzando Core-Plot con ScatterPlot per rappresentare le linee multiple. Quando si scorre, il grafico si sposta su salti e si blocca. Non so cosa succede Mi potete aiutare? Ecco il mio codice:

#import <UIKit/UIKit.h> 
#import "CorePlot-CocoaTouch.h" 
@interface TemporalLineViewController:UIViewController<CPTPlotDataSource, 
CPTScatterPlotDelegate> 

@property (strong, nonatomic) IBOutlet CPTGraphHostingView *hostingView; 

@end 


@interface TemporalLineViewController(){ 
    NSMutableDictionary *dates; 
} 
@property (nonatomic, readwrite, strong) NSArray *plotData; 
@end 

@implementation TemporalLineViewController 
-(CPTGraph *)createGraph{ 
    initWithFrame:CGRectMake(viewGraph.frame.origin.x, viewGraph.frame.origin.y, 500, viewGraph.frame.size.height)]; 

    CPTGraph *graph = [[CPTXYGraph alloc] initWithFrame:hostingView.bounds]; 
    [graph applyTheme:[CPTTheme themeNamed:kCPTSlateTheme]]; 
    hostingView.hostedGraph=graph; 

    // Axes 
    CPTXYAxisSet *axisSet = (CPTXYAxisSet *)graph.axisSet; 
    CPTXYAxis *x   = axisSet.xAxis; 
    x.majorIntervalLength   = CPTDecimalFromDouble(ONEDAY); 
    x.orthogonalCoordinateDecimal = CPTDecimalFromDouble(0.0); 
    x.minorTicksPerInterval  = 0; 
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; 
    [dateFormatter setDateFormat:@"dd/MM/yyyy"]; 
    CPTTimeFormatter *timeFormatter = [[CPTTimeFormatter alloc] initWithDateFormatter:dateFormatter]; 
    timeFormatter.referenceDate = [[NSDate alloc]init]; 
    x.labelFormatter   = timeFormatter; 
    x.labelRotation    = CPTFloat(M_PI_4); 

    CPTXYAxis *y = axisSet.yAxis; 
    y.hidden=YES; 
    y.orthogonalCoordinateDecimal = CPTDecimalFromInt(0); 
    return graph; 
} 

-(void)createScatterPlot{ 

    CPTGraph * graph = [self createGraph]; 

    CPTXYPlotSpace *plotSpace = (CPTXYPlotSpace *)graph.defaultPlotSpace; 
    NSTimeInterval xLow  = 0.0; 
    plotSpace.xRange = [CPTPlotRange plotRangeWithLocation:CPTDecimalFromDouble(xLow) length:CPTDecimalFromDouble(ONEDAY * 10.0)];

Avete reimpostare la dimensione del contenuto del vostro vista di scorrimento? In caso contrario, ripristinare la dimensione del fotogramma di ScatterPlot se questa è solo la vista all'interno della vista di scorrimento.
