CorePlot
安装：
下载地址：https://code.google.com/p/core-plot/步骤：
# Install Binaries for iOS
1. Copy the **CorePlotHeaders** to your Xcode project
2. Copy **libCorePlotCocoaTouch.a** to your Xcode project
3. Add the following flags to "Other Linker Flags" in your target build settings:
`-ObjC -all_load`
4. Add the **QuartzCore** framework to the project.
注意：当使用上面的方法，遇到ld: library not found for -lCorePlot-CocoaTouch 的错误，可以只操作第1和2步，然后将 libCorePlotCocoaTouch.a的名称改为CocoaTouch.a
