AAChartKit 中没有这部分依赖项, 所以说不支持此功能.

  1. 简单一点的, 参考 demo 中 AAMoveOverEventMessageModel 
@interface AAMoveOverEventMessageModel : NSObject

@property (nonatomic, strong) NSNumber *x; 
@property (nonatomic, strong) NSNumber *y;
@property (nonatomic, copy)   NSString *category;
@property (nonatomic, strong) NSDictionary *offset;
@property (nonatomic, assign) NSUInteger index;

@end

的相关使用示例.
