The H-R diagram, a typical case for teaching improvement on scientific methods in astronomy, is used to revealing the process of the stellar evolution. The diagram was created and improved by induction, while the related explain on stellar evolution by deduction. Therefore, the relationship between such inductive diagram and the deductive explain may calls methodology confusion. It is possible to clarify the confusion by exploring the diagram among the modern astronomy history, analyzing the theory of stellar internal structure developed in the same era and visualizing the generation of the diagram. It is expected to further understand the nature of the diagram by such efforts.
