How to add a View to a ScrollView at a specific position?

I have a UIView with a rectangle size of (414,736). I made a ScrollView 50 in width and 50 in height bigger than UIView. When I add UIView to ScrollView, UIView stays horizontally is OK, but in vertical it is located at the bottom of the ScrollView. So that my scrolling part is the top part. But I want UIView stay on the top part and the bottom part becomes the scrolling area. How can I locate the UIView with a specific location onto the ScrollView? The following code shows how ScrollView is implemented.

    CGRect screenRect = [[UIScreen mainScreen] bounds];
    self.scrollView=[[UIScrollView alloc] initWithFrame:screenRect];
    self.scrollView.delegate = self;
    self.scrollView.clipsToBounds = YES;
    [self.scrollView addSubview:self.drawChart];
    self.scrollView.contentSize=CGSizeMake(screenRect.size.width+100,screenRect.size.height+50);
    self.scrollView.decelerationRate = UIScrollViewDecelerationRateFast;
    self.scrollView.backgroundColor = [UIColor colorWithRed:0.564 green:0.439 blue:0.561 alpha:1];
    self.view=self.scrollView;

EDIT:

- (void)viewDidLoad {
    [super viewDidLoad];
    CGRect screenRect = [[UIScreen mainScreen] bounds];
    //Database
    dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    docsDir = [dirPaths objectAtIndex:0];
    // Build the path to the database file
    databasePath = [[NSString alloc]initWithString:[docsDir stringByAppendingPathComponent: @"RECORDS.db"]];
    //scroll view
    //
    self.scrollView=[[UIScrollView alloc] initWithFrame:screenRect];
    self.scrollView.delegate = self;
    self.scrollView.clipsToBounds = YES;

    [self.scrollView addSubview:self.drawChart];
    CGRect frame = self.drawChart.frame;
    frame.origin = CGPointZero;
    self.drawChart.frame = frame;
    self.scrollView.contentSize=CGSizeMake(screenRect.size.width+100,screenRect.size.height+50);
    self.scrollView.decelerationRate = UIScrollViewDecelerationRateFast;
    self.scrollView.backgroundColor = [UIColor colorWithRed:0.564 green:0.439 blue:0.561 alpha:1];
        self.view=self.scrollView;
}

Thanks

after adding the chartview to the scrollview

[self.scrollView addSubview:self.drawChart];

do the following:

CGRect frame = self.drawChart.frame;
frame.origin = CGPointZero;
self.drawChart.frame = frame;
