PURPOSE:To provide a data system capable of discriminating visionally atmospheric conditions such as the adaptability, comfortableness and the like of the atmosphere when they are determined by a plurality of factors, by displaying the conditions as positions on a plane whose coordinates represent measured values of these factors. CONSTITUTION:A plurality of properties of the atmosphere are picked up in terms of measured values by a sensor, and these two measured values are represented on biaxial coordinates, thus displaying the atmospheric conditions as positions of dots on a plane. Furthermore, in order to visionally clarify the meanings of positions of measured points, adapted zones, comfortable zones, and the like are designated beforehand in terms of line blocks, colors, characters and the like. For example, if the optimum zone is depicted beforehand on a display panel using the measured values of NOx and dust as coordinates during the operation of a kerosene boiler, even those non-skilled in the art can easiy catch the normal operational condition and even any slight fluctuation in the measured value can be discriminated whether it is in an allowable range or not. |
