The paper presents the results of the use of graphical tests for the pre-forecast analysis of time series characterizing the allergodermatosis incidence of workers in the chemical and pharmaceutical industry in Ukraine. The method is based on the decomposition of phase portraits of time series into quasi-cycles, the characteristics of which allow estimating the risk of erroneous forecasting. To strengthen the structuredness of the data, it is proposed to carry out the procedure of aggregating time series. Figs.: 5. Tabl.: 1.
