With pst-bar, one may use pstricks to produce bar charts directly from a data file. This package is still in the beta stage --- the usual caveats pertaining to beta software apply. Additional features and improved (in both content and layout) documentation will be provided as the code stabilizes. INSTALLATION: pst-bar consists of three files: pst-bar.sty, pst-bar.tex, and pst-bar.pro. Place the first two anywhere your installation can find them (typically $LOCALTEXMF/tex/latex/pst-bar for pst-bar.sty and $LOCALTEXMF/tex/generic/pst-bar for pst-bar.tex). Place pst-bar.pro where dvips can find it, typically in the pstricks subdirectory of your dvips directory (i.e., $LOCALTEXMF/dvips/pstricks). DOCUMENTATION: See pst-bar-doc.ps or pst-bar-doc.pdf for details on using pst-bar.
