PURPOSE:To know the fine variation of observation and measurement data containing error data by removing data corresponding to external set conditions from specific-width data which are rearranged according to a rule. CONSTITUTION:An increasing order sorting processing part 8 rearrange data, read out of a storage device 1 by a data read part 2 to every specific width, in the increasing order. A data extraction part 5 discards M pieces of data from the data, which are rearranged by the processing part 8 in the increasing order, each from the larger side and smaller side. Consequently, error data is removed and an arithmetic processing part 6 and a display position indication part 7 perform graphic processing so that the variation range of data to be scaled almost matches the full scale of a display device 3. Therefore, when a graphic display is made, normal data are not compressed with error data and normal fine variation can be displayed. |
