PPROBLEM TO BE SOLVED: To allow a user to compare data before and after changes appropriately. PSOLUTION: A data display system 10 displays data based on measurement data Cj measured by each measurement facility Yi. In the data display system 10, a data synchronization device 14 associates synchronous data to be a set of the measurement data Cj as a result of the measurement facility Yi measuring a plurality of workpieces among a plurality of measurement facilities Yi. When a manufacturing condition of a working facility Xj is changed, a data comparator 16 acquires a time of change, estimates a time for change in which the measurement data of the measurement facility Yj adjacent to a downstream side of the working facility Xj, uses the estimated time for change and the synchronous data associated among the plurality of measurement facilities Yj, and creates comparison data before change on the basis of measurement data before change and comparison data after change on the basis of measurement after change. A data display device displays comparison data before change and comparison data after change separately according to the measurement facilities Yj. PCOPYRIGHT: (C)2008,JPO&INPIT
