title: Core-plot real-time-data for redraw plot
body: <p>I have 4 hosting view on 1 self.view</p>
  
  <pre><code>self.hostView.frame = CGRectMake(0.0, 0.0, 512.0, 352.0);
  self.hostView2.frame = CGRectMake(512.0, 0.0, 512.0, 352.0);
  self.hostView3.frame = CGRectMake(0.0, 352.0, 512.0, 352.0);
  self.hostView4.frame = CGRectMake(512.0, 352.0, 512.0, 352.0);
  </code></pre>
  
  <p>On hostingView i make plot. i have 4 arrays with some data.</p>
  
  <pre><code>self.arr1 = [NSMutableArray arrayWithObjects:
                  [NSDecimalNumber numberWithFloat:36.23],
                  [NSDecimalNumber numberWithFloat:38.44],
                  nil];
  self.arr2 = [NSMutableArray arrayWithObjects:
                  [NSDecimalNumber numberWithFloat:36.23],
                  [NSDecimalNumber numberWithFloat:38.44],
                  nil];
  self.arr3 = [NSMutableArray arrayWithObjects:
                  [NSDecimalNumber numberWithFloat:36.23],
                  [NSDecimalNumber numberWithFloat:38.44],
                  nil];
  self.arr4 = [NSMutableArray arrayWithObjects:
                  [NSDecimalNumber numberWithFloat:36.23],
                  [NSDecimalNumber numberWithFloat:38.44],
                  nil];
  </code></pre>
  
  <p>I use timer that call method generator</p>
  
  <pre><code>[NSTimer scheduledTimerWithTimeInterval:2 target:self selector:@selector(generator) userInfo:nil repeats:YES];
  
  -(void)generator
  {
      [self.bd1 removeObjectAtIndex:0];
      NSInteger count=arc4random()%30;
      [self.bd1 addObject:[NSNumber numberWithInteger:(20+count)]];
      [graph reloadData];
  
      [self.bd2 removeObjectAtIndex:0];
  
      [self.bd2 addObject:[NSNumber numberWithInteger:(20+count)]];
      [graph2 reloadData];
  
      [self.bd3 removeObjectAtIndex:0];
  
      [self.bd3 addObject:[NSNumber numberWithInteger:(20+count)]];
      [graph3 reloadData];
  
      [self.bd4 removeObjectAtIndex:0];
  
      [self.bd4 addObject:[NSNumber numberWithInteger:(20+count)]];
      [graph4 reloadData];
  }
  </code></pre>
  
  <p>It's work 38 seconds and than freezes. What i can do for make it working fine. I need to reload data for making real-time</p>
  
  <p><strong>Any ideas?</strong></p>
