我在横向模式下实现了一个带有散点图的图表。我已经在绘图空间上启用了用户交互。图表视图似乎只能识别图表左半部分的用户交互，而不能识别右半部分的用户交互。我确保没有与图形视图重叠的视图，并且它位于视图堆栈的顶部。谁能建议可能出了什么问题？.. 谢谢
代码在这里：
图主机的初始化：
-(void)initgraphhost{
CGRect graphcontainer=CGRectMake(0,0,568,300);
self.graphhostview = [(CPTGraphHostingView *) [CPTGraphHostingView alloc] initWithFrame:graphcontainer];
self.graphhostview.backgroundColor=[UIColor clearColor];
self.graphhostview.allowPinchScaling = YES;
[self.view addSubview:self.graphhostview];
}
添加图表：
-(void)AddGraph:(NSString *)graphname tographcontainer:(CPTGraphHostingView *)host{
graph = [[CPTXYGraph alloc] initWithFrame:host.bounds];
graph.borderColor=(__bridge CGColorRef)([UIColor clearColor]);
[graph applyTheme:[CPTTheme themeNamed:nil]];
