Display system, display method, and non-transitory computer readable medium

A display method comprising:

• acquiring principal components, the principal components being results of principal component analyses on a plurality of analysis subject data;
• acquiring a principal component score of the analysis subject data to be displayed;
• receiving a change in the principal component score of the analysis subject data to be displayed from a user;
• outputting reconstructed data obtained by reconstructing analysis subject data based on the principal component and the changed principal component score;
• evaluating a difference between the reconstructed data and reference data;
• and
• displaying at least one of the reconstructed data and the reference data while emphasizing a data area according to magnitude of the difference.

A non-transitory computer readable medium storing a program for causing a computer to:

• acquire principal components, the principal components being results of principal component analyses on a plurality of analysis subject data;
• acquire a principal component score of the analysis subject data to be displayed;
• receive a change in the principal component score of the analysis subject data to be displayed from a user;
• output reconstructed data obtained by reconstructing analysis subject data based on the principal component and the changed principal component score;
• evaluate a difference between the reconstructed data and reference data;
• and
• display at least one of the reconstructed data and the reference data while emphasizing a data area according to magnitude of the difference.
