The following classes are used to perform data analysis. For more details, please refer to the Origin C: Origin C Reference: Classes: Analysis chapter in the help document of OriginC.

Class Brief Description

This class provides a method for accessing the information of the fitting function, as well as the current evaluation state that is generated by implementing the fitting function in Origin C.


This class is the higher level Origin class. It wraps the NLFit class with a friendly interface to aid in implementing the fitting evaluation procedure. It is the kernel of the NLFit dialog. This class is recommended for coding in Origin C, because it takes care of all the complexities that arise from the process of interfacing to Origin.
