使用CorePlot 1.6版.运行iOS 8.3.

我正在使用Core-Plot和ScatterPlot来表示多行.当我滚动时,图形移动到跳跃并锁定.我不知道会发生什么.你能帮助我吗？这是我的代码:

#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 = …
