How do I get this code to work with my CPTGraphHostingView?

[Chizbang]

Hey!
I know im asking allot of questions about Core Plot, im really sorry, but I keep bumping into problems.
This is how far I have gotten:


The Core Plot view is at the top of my ViewController.
The reason why I want it like that is because I want text underneath.
Anyway:
This is what I did to get this far:
In MyProjectViewController.m's view did load method:

plotView initWithFrame:CGRectMake(0, 0, 320, 200)];
	[self.view addSubview:plotView];
	[plotView release];
	CPTTestAppBarChartController * barChartTopViewController= [[CPTTestAppBarChartController alloc] init];
	[barChartTopViewController viewDidLoad];

I implemented the Core Plot view in the Interface builder and linked the plotView variable to the Core Plot View in the Interface Builder.
The code above makes the Core Plot view set its size so I can have it at the top of the main view controller.
And the [barChartTopViewController viewDidLoad] is to activate the code within the viewDidLoad method in the barChartTopViewController.
Here is the barChartTopViewControllers .ms code:
[Objective C] #import "barChartTopViewController.h" @implementation barChartTopViewController - Pastebin.com
Thats the code thats in the barChartTopViewController.m (I made that class in the interface builder by pressing: File > Write Class Files)
I know its simple, but please go easy on me, im a total noob to all this, I just want to experiment with this stuff.
The Core Plot Example Project has the exact same code and configuration (Except the bar chart is an separate view rather then it being integrated into a view) so I have copied everything and It still doesn't work.
What do I need to do to get the code to execute to the CPTGraphHostingView (The code in the bar chart class should have made a bar chart but it did not)?
I know I have made a similar question, but I have tried a different way to last time.
So please, help me out.
I would be really grateful.
Thank you very very much.

You didn't post the whole statement that creates a plotview.

The first line you quoted:

plotView initWithFrame:CGRectMake(0, 0, 320, 200)]

Would not compile like that, since it has a closing bracket but not an opening bracket.

In Cocoa, you create objects by first allocating them, then sending them an init message of some sort. That line should read something like this:

plotView = [[PlotViewClass alloc] initWithFrame:CGRectMake(0, 0, 320, 200)];

I don't know what class your plotView object is supposed to be, so I just used "PlotViewClass" above. Replace that with the class name for this object.

Also, further down, you create a CPTTestAppBarChartController object, then never do anything with it.

	CPTTestAppBarChartController * barChartTopViewController= [[CPTTestAppBarChartController alloc] init];
	[barChartTopViewController viewDidLoad];

Is that a subclass of UIViewController? If so, you probably need to make that the parent class for the whole screen that will contain your bar chart. Except under iOS5 on the iPad, you really shouldn't mix the contents of multiple view controllers on a single screen.

Finally, you probably shouldn't be calling a view controller's viewDidLoad method directly. The system calls that method when view controllers are created and their views get loaded. You rarely, if ever, call them yourself.
