我的要求是使用hi-chart获取图表,如下所示。

我尝试了所有类型的柱形图。这是我发现的东西。

Column chart Negetive

尝试使用偏移,但标签重叠,偏移需要根据数据和屏幕进行更改,这也是一个挑战。

use offset

代码:

- (void)playVideoWithUrl:(NSString *) videoUrl 
{
   if (player != nil) {
   [player.currentItem removeObserver:self forKeyPath:@"status"];
   [player.currentItem removeObserver:self forKeyPath:@"playbackLikelyToKeepUp"];
   }
AVURLAsset * asset = [[AVURLAsset alloc]initWithURL:[NSURL URLWithString:videoUrl]
                                            options:nil];    
AVPlayerItem * item = [[AVPlayerItem alloc]initWithAsset:asset];
// Add KVO to detech status of loading video
[item addObserver:self
       forKeyPath:@"status"
          options:0
          context:nil];
// Add KVO to detech when playback is loading buffer successfully
[item addObserver:self
       forKeyPath:@"playbackLikelyToKeepUp"
          options:0
          context:nil];
// Detect when playback completed
[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(playerItemDidReachEnd:)
                                             name:AVPlayerItemDidPlayToEndTimeNotification
                                           object:[player currentItem]];
[player replaceCurrentItemWithPlayerItem:item];
[player play];
}

我能解决这个问题的任何其他方式。
