SHORT ABSTRACT:
 These GRAF subroutines produce high quality x-y graphs
of tabulated functions.  The graphs are labelled,
and the endpoints of the axes are chosen to be nice
numbers depending on the range of data point values.

LONGER ABSTRACT:
 In scientific or engineering applications it is common
to want to plot an x-y function, without being too
concerned about the range of values and so on.  The
subroutines in this collection plot tabulated functions
with autoscaled axes, axis labels and a number of options
as to line type and plotting symbols.  Depending on the
output device used, the plots are of sufficient quality
to be published in professional journals.
 Also included are several device dependent libraries
for generating the actual plot on several devices such
as Tektronix 4010 compatible terminals, HP7221 plotters,
Epson FX-80 printers, and a device-independent interface
for generating plotfiles which may later be plotted on
any and all supported devices.  The actual program is
independent of the plotting device; the choice is made
at task build time.
