This is probably a basic newbie question but I have got stuck on this. Trying to set up Core Plot but have some issues.

By looking at the CPTestApp I am trying just to draw anything but I always get an crash in CPTPlatformSpecificFunctions because the NSGraphicContext is nil. 

```
void CPTPushCGContext(CGContextRef newContext)
{
    if ( newContext ) {
        if ( !pushedContexts ) {
            pushedContexts = [[NSMutableArray alloc] init];
        }
        [pushedContexts addObject:[NSGraphicsContext currentContext]];
        [NSGraphicsContext setCurrentContext:[NSGraphicsContext graphicsContextWithGraphicsPort:newContext flipped:NO]];
    }
}

```

Why does [NSGraphicsContext currentContext] returns nil? I would appreciate any hints. The demo app seems to call the init from the application delegate like me.

EDIT, here is my call to Coreplot:

ApplicationDeletegate.h

```
#import <CorePlot/CorePlot.h>

@property (nonatomic, readwrite, strong) IBOutlet CPTGraphHostingView *graphHostView;

```

ApplicationDeletegate.m (yes, I know you should not have so much code here)

```
-(void)awakeFromNib
{
    [super awakeFromNib];
    [self setupGraph];
}

-(void)setupGraph
{

    CPTGraph *graph = [[CPTXYGraph alloc] initWithFrame:graphHostView.bounds];
    graph.plotAreaFrame.masksToBorder = NO;
    graphHostView.hostedGraph = graph;

    [graph applyTheme:[CPTTheme themeNamed:kCPTPlainBlackTheme]];
    graph.paddingBottom = 30.0f;
    graph.paddingLeft  = 30.0f;
    graph.paddingTop    = -1.0f;
    graph.paddingRight  = -5.0f;

    CPTMutableTextStyle *titleStyle = [CPTMutableTextStyle textStyle];
    titleStyle.color = [CPTColor whiteColor];
    titleStyle.fontName = @"Helvetica-Bold";
    titleStyle.fontSize = 16.0f;

    NSString *title = @"Portfolio Prices: April 23 - 27, 2012";
    graph.title = title;
    graph.titleTextStyle = titleStyle;
    graph.titlePlotAreaFrameAnchor = CPTRectAnchorTop;
    graph.titleDisplacement = CGPointMake(0.0f, -16.0f);

}

```

Is awakeFromNib too early? Have I missed something?
