• a level display unit configured to display each of the reference elements of the reference object in correspondence with the corresponding level, and,
• a correspondence display unit configured to display the comparison elements of the comparison object in the corresponding level among the levels formed in the Z-axis direction,
• the reference object and the comparison objects are displayed side by side in a substantially bar shape extending in the Z-axis direction.
