Axis is a locally implemented 2D plot utility. It was developed by John Richardson and Bob Pearson at the University of California, Santa Barbara and modified by Douglas Toussaint, currently of the University of Arizona. It is primitive compared with major plotting packages, such as gnuplot, Plot79, IMSL Exponential Graphics, and the plotting facilities of symbolic manipulation programs like Maple and Mathematica. However, it is extremely easy to use, so it is ideal for classroom instruction. Even so, it produces publication quality graphs. For further information, see axis.ps or axis.txt

Hist is a simple histogramming utility. (A histogram is used in the
statistical analysis of data to display the frequency of occurrences
of a variable within a set of regularly spaced ranges. For example, a
study of the heights of physics majors might produce a table showing
the numbers of physics majors in the study population with heights
falling within a series of height intervals spaced 1 cm apart.) The
**hist** utility can be used in conjunction with **axis** to
produce a graphical display of the histogram.
