{Plots in \LaTeX: Gnuplot, Octave, make} {Boris Veytsman and Leila Akhmadeyeva} {Making scientific and engineering documents with complex plots may be difficult and time consuming. This is especially true if data updates require rebuilding of plots and documents. In this report a workflow based on integration of \AllTeX, Gnuplot and Octave using Makefiles in a Unix-based environment is proposed and discussed in detail. }
