I am trying to implementing plot graphs using the link.

http://www.switchonthecode.com/tutorials/using-core-plot-in-an-iphone-application

But as for support i need to add plot files & frameworks.

How to install CorePlot framework correctly?

I am using xcode 4.1

Copy the CorePlotHeaders to my Xcode project

Copy libCorePlotCocoaTouch.a to my Xcode project

Add to Other Linker Flags in my target build settings: -ObjC -all_load

in xcode 4.1

And please provide me any other best tutorials for Graph applications in xcode4.1

I have an error causes to crash the app
