Abstract: PURPOSE:To output compressed outline data under the optimum condition while suppressing the strain of a reproduced waveform to the min. by compressing outline data to the data at every size corresponding to the resolving power in the time series direction of a two-dimensional display means. CONSTITUTION:A data processing apparatus 1 converts the chromatogram from a chromatograph 2 to digital data by an A/D converter 11 to store said data in an external memory 12 and performs analytical processing operation such as the detection of the peak of the chromatogram taken in a CPU 13 and the calculation of the area of the peak. In such a case that the taken-in chromatogram is reproduced, even when the number of data is shortened to 1/2 when there are many data at every pixel on a time axis wherein one measure is set to one pixel, an apparent shape does not change. When there are the data at the max. and min. points in N points with respect to the resolving power in the time axis direction of a display apparatus, that is, with respect to one pixel width, the waveform thereof can be expressed in an apparently perfectly accurate state. Therefore, with due regard to the resolving power of the display apparatus, waveform data is compressed to the data at the max. and min. points within the range thereof.
