xcode iphone 4 core plot framework, UIView trouble with storyboard

Question

Hi have followed this tutorial using Core plot framework http://www.switchonthecode.com/tutorials/using-core-plot-in-an-iphone-application

My project compiles, but crash when trying the view. I think i has to do with UIView / storyboard. Although i've changed the class in my UIView till CPTGraphHostingView i still get the error below

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIView setHostedGraph:]: unrecognized selector sent to instance 0x6b8afe0'

Any ideas ? Code below

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.

    //CPTGraphHostingView *hostingView = (CPTGraphHostingView *) self.view;
    //CPTGraphHostingView *hostingView = [[CPTGraphHostingView alloc] initWithFrame:self.view.bounds];
    //[self.view addSubview:hostingView];
    hostingView.hostedGraph = graph;

    graph.plotAreaFrame.plotArea.fill = [CPTFill fillWithColor:[CPTColor whiteColor]];


    hostingView.hostedGraph = graph;
    graph.paddingLeft = 20.0;
    graph.paddingTop = 20.0;
    graph.paddingRight = 20.0;
    graph.paddingBottom = 20.0;

    CPTXYPlotSpace *plotSpace = (CPTXYPlotSpace *)graph.defaultPlotSpace;
    plotSpace.xRange = [CPTPlotRange plotRangeWithLocation:CPTDecimalFromFloat(-6) 
                                                    length:CPTDecimalFromFloat(12)];
    plotSpace.yRange = [CPTPlotRange plotRangeWithLocation:CPTDecimalFromFloat(-5) 
                                                    length:CPTDecimalFromFloat(30)];

    CPTXYAxisSet *axisSet = (CPTXYAxisSet *)graph.axisSet;

    CPTMutableLineStyle *lineStyle = [CPTMutableLineStyle lineStyle];
    lineStyle.lineColor = [CPTColor blackColor];
    lineStyle.lineWidth = 2.0f;

    axisSet.xAxis.majorIntervalLength = [[NSNumber numberWithInt:5] decimalValue];
    axisSet.xAxis.minorTicksPerInterval = 4;
    axisSet.xAxis.majorTickLineStyle = lineStyle;
    axisSet.xAxis.minorTickLineStyle = lineStyle;
    axisSet.xAxis.axisLineStyle = lineStyle;
    axisSet.xAxis.minorTickLength = 5.0f;
    axisSet.xAxis.majorTickLength = 7.0f;
    axisSet.xAxis.labelOffset = 3.0f;

    axisSet.yAxis.majorIntervalLength = [[NSNumber numberWithInt:5] decimalValue];
    axisSet.yAxis.minorTicksPerInterval = 4;
    axisSet.yAxis.majorTickLineStyle = lineStyle;
    axisSet.yAxis.minorTickLineStyle = lineStyle;
    axisSet.yAxis.axisLineStyle = lineStyle;
    axisSet.yAxis.minorTickLength = 5.0f;
    axisSet.yAxis.majorTickLength = 7.0f;
    axisSet.yAxis.labelOffset = 3.0f;

    CPTScatterPlot *xSquaredPlot = [[CPTScatterPlot alloc] initWithFrame:graph.defaultPlotSpace.accessibilityFrame];
    xSquaredPlot.identifier = @"X Squared Plot";
    CPTMutableLineStyle *ls1 = [CPTMutableLineStyle lineStyle];
    ls1.lineWidth = 1.0f;
    ls1.lineColor = [CPTColor redColor];
    xSquaredPlot.dataLineStyle = ls1;
    xSquaredPlot.dataSource = self;
    [graph addPlot:xSquaredPlot];

    CPTPlotSymbol *greenCirclePlotSymbol = [CPTPlotSymbol ellipsePlotSymbol];
    greenCirclePlotSymbol.fill = [CPTFill fillWithColor:[CPTColor greenColor]];
    greenCirclePlotSymbol.size = CGSizeMake(2.0, 2.0);
    xSquaredPlot.plotSymbol = greenCirclePlotSymbol;  

    CPTScatterPlot *xInversePlot = [[CPTScatterPlot alloc] initWithFrame:graph.defaultPlotSpace.accessibilityFrame];

    xInversePlot.identifier = @"X Inverse Plot";
    CPTMutableLineStyle *ls2 = [CPTMutableLineStyle lineStyle];
    ls2.lineWidth = 1.0f;
    ls2.lineColor = [CPTColor blueColor];
    xInversePlot.dataLineStyle = ls2;
    xInversePlot.dataSource = self;
    [graph addPlot:xInversePlot];
}

I added -Load_All and -ObjC in the compiler options, then it seems to be OK :-)
