DATAPLOT Summary

Introduction DATAPLOT is a powerful and flexible program for performing scientific, engineering, statistical, mathematical, and graphical analysis. It is an interactive, command-driven language/system with English-like syntax. It was developed in response to data analysis problems encountered at the National Bureau of Standards (now the National Institute of Standards and Technology) DATAPLOT is primarily written in Fortran-77, highly portable, and runs on mainframes, minicomputers, workstations, and PC's. Its capabilities include:
