  • Using Core Plot in an iPhone Application
    11/13/2010 - 12:30

    Hi,

    Finally I have got the code working: The only one change that you have to do apart from look into the below code is, in the interface builder use CPGraphHostingView instead of CPLayerHostingView for your view class.

    If you want to install the core-plot using sdk and not the way it is described above, then please go over the the following link

    Hi,

    I tried everything that has been said here but I am getting following error

    Library not found for -lCorePlot

    Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc-4.2 failed with exit code 1

    I am using 4.2 compiler and 4.1 iOS

    Please help

    Thanks,
