In a chromatographic analyzer which performs a measurement on multiple compounds for each of the multiple samples, a data-analysis processor calculates, for each sample, multiple pieces of numerical information obtained by data analysis on multiple compounds, based on measurement data. A table creator creates a two-dimensional table by arranging sample identifier in one direction of the table and compound identifier in the other direction, and assigning numerical information obtained for a combination of one sample and one compound to a cell of the table corresponding to the combination. A cell selection receiver displays the table on a display screen and receives a selection of a cell or cells according to a user operation on the displayed table. A selected information outputter outputs or displays the numerical information in the selected cell(s) in a predetermined format along with the sample and compound identifiers corresponding to the cell(s).
