TRIPLT22.ZIP    Plot ternary diagrams using HP-GL/2 commands

TriPlot is an MS-DOS shareware program that generates HP-GL/2
instructions for plotting three-component data on a ternary diagram.
HP-GL/2 is the new standardized version of the Hewlett-Packard
Graphics Language.  It is available, for example, with HP's series
of LaserJet III printers and DraftMaster plotters.

The user can redirect the HP-GL/2 commands to a file for
printing/plotting at a later time or for importing into a
print-utility or drawing program.  A data point can be represented
by one of eight possible symbols drawn, in the case of a plotter,
by one of eight possible pens.  It can also be labelled with a
user-supplied identification.  Furthermore, the user has the option
of (a) toggling the legend on and off, (b) drawing the whole diagram
or enlarging a corner, (c) displaying one of five pre-defined grid
systems, (d) overlaying one of twenty-two program-supplied zonation
schemes, and (e) plotting the sample mean and standard deviation of
the data.  Line segments and tie-lines can also be drawn.
