pgfplots

pgfplots - Create normal/logarithmic plots in two and three dimensions for LaTeX/TeX/ConTeXt.

pgfplotstable - Loads, rounds, formats and postprocesses numerical tables.

PGFPlots draws high--quality function plots in normal or logarithmic scaling with a user-friendly interface directly in TeX. The user supplies axis labels, legend entries and the plot coordinates for one or more plots and PGFPlots applies axis scaling, computes any logarithms and axis ticks and draws the plots. It supports line plots, scatter plots, piecewise constant plots, bar plots, area plots, mesh and surface plots, patch plots, contour plots, quiver plots, histogram plots, polar axes, ternary diagrams, smith charts and some more.

Pgfplots is based on Till Tantau's package PGF/TikZ (pgf).

Pgfplotstable displays numerical tables rounded to desired precision in various display formats, for example scientific format, fixed point format or integer, using TeX's math facilities for pretty printing. Furthermore, it provides methods for table postprocessing.

Please take a look at doc/latex/pgfplots/pgfplots.pdf and doc/latex/pgfplots/pgfplotstable.pdf.
