+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, supporting line plots, scatter plots, piecewise constant
+plots, bar plots, area plots, mesh-- and surface plots and some more.
+PGFPlots is based on PGF/TikZ (PGF); it runs equally for LaTeX/TeX/ConTeXt.")
