Abstract
The present invention makes a user properly compare data before and after a change with each other. A data display system displays data based on measurement data obtained by measuring equipments. In the data display system, a data synchronizer associates synchronous data as a set of measurement data obtained from a plurality of works by the measuring equipments with each other among the measuring equipments. When manufacturing parameters of a processing equipment are changed, a data comparator obtains time of the change, estimates time of a change in measurement data of the measuring equipment next to the processing equipment on the downstream side and, using the estimated change time and the synchronous data associated with each other among the plurality of measuring equipments, generates comparison data before the change based on the measurement data before the change, and comparison data after the change based on the measurement data after the change. A data display displays the comparison data before the change and the comparison data after the change by the measuring equipment.
