A method for analysis in which a user can readily compare expression data and a pathway with a computer is provided as an alternative to subjective comparison or manual comparison of the expression data and the pathway according to certain criteria. Expression data of a protein/gene other than a target protein/gene is constructed so as to fit in with a pathway on the basis of the target protein/gene expression data; and the protein/gene expression data, in the constructed structure of the expression data, fitting in with the pathway is highlighted while the constructed structure of the expression data is displayed on a display.
