Thanks in Advance

    just try this way may be helped you :

    CPTGraphHostingView *hostingView = [[CPTGraphHostingView alloc] initWithFrame:CGRectMake(10, 70, 768, 1004)];
    hostingView.tag=1;
    [self.view addSubview:hostingView];
//  [hostingView addSubview:OptionBtn];
    barChart = [[CPXYGraph alloc] initWithFrame:self.view.bounds];
    //barChart.backgroundColor = [UIColor colorWithPatternImage: [UIImage imageNamed:@"FinalGraph.png"]];
    hostingView.hostedGraph = barChart;
