This paper is devoted to the problem of visualization of multiparameter tabular numerical data on the example of processing the results of the study of critical two-phase flow through a spherical particles bed. An overview of interactive and streaming methods for working with tabular data is presented. The task of automating the plotting of scatter diagrams with several rows is solved by means of the programs gnuplot, gawk, sort, and their combination using data pipes. Special attention is paid to minimizing the efforts of the researcher, spent on updating the diagrams when entering new data and changing the requirements for the design of diagrams.
