The Interactive Plotting Program GRAPH - Revised Manual.

Abstract

This report is a user guide for the interactive graphics program called GRAPH and replaces the earlier Materials Research Laboratories technical note, MRL-TN-485. The suggestions of users and the expansion of the capabilities of the program have led to this revision. GRAPH is a command driven interactive program which allows the user, with only limited computer experience, to display and modify graphical output. The program can plot data on linear or logarithmic axes. The axis scales can be set by the user or autoscaled by the program. Labels can be added or changed and text can be written to any part of the plot. Data can be plotted as points, histograms or lines. GRAPH has commands which allow for simple data reduction. Data can be multiplied, divided, added, subtracted by a constant value or by a second set of data. Data can also be exponentiated, integrated, differentiated or smoothed. A least-squares polynomial or a more general function can be fitted to the data. GRAPH was written in FORTRAN 77 on the VAX 11/780 computer at the Materials Research Laboratories.
