According to the Ray Wenderlich tutorial, I done the following :
Step 1 - I downloaded CorePlot_1.4.zip on the official website
Step 2 - I added to my project the CorePlotHeaders folder and the static library named libCorePlot-CocoaTouch.a (checking “Copy items into destination group’s folder (if needed)”)
Step 3 - I added into Other Linker Flags field the following : -ObjC
Step 4 - I checked into Link Binary with Libraries if libCorePlot-CocoaTouch.a and QuartzCore frameworks were here
Result : When I compile my project, it works fine when I'm using Iphone Retina (4-Inch). But when I'm using Iphone Retina (4-Inch 64-bit) I got the following message when I try to build and run :
ld: warning: ignoring file /blah/blah/libCorePlot-CocoaTouch.a, missing required architecture x86_64 in file /blah/blah/libCorePlot-CocoaTouch.a (3 slices)
Here the complete message :

I spent several hours on this issue... Please help...
If you want a 64-bit version of Core Plot, you'll have to build a new version of the static library. Arm64 builds require iOS 7 but Core Plot supports earlier versions, too, so the pre-built library is 32-bit only.
Open CorePlot-CocoaTouch.xcodeproj
and change the architecture settings to "Standard Architectures (including 64-bit)". Either build the "Universal Library" target and include the resulting static library in place of the one included with Core Plot 1.4 or use the dependent project setup instead.
CorePlot has released 1.5.1 to work with Xcode 5.1. You only need to copy the CorePlotHeaders folder and the libCorePlot-CocoaTouch.a file to your project.
You can download it from here.
