PIPER10.ZIP     Plot Piper diagrams using HP-GL/2 commands

Piper is an MS-DOS shareware program that generates HP-GL/2 instructions
for plotting chemical water data on a Piper diagram.  It also computes
and reports the charge-balance errors.  Water analyses exceeding a
user-specified error tolerance on the electroneutrality condition are
excluded from the plot.

The user can direct the error report to a printer or to a file.  In
addition, the HP-GL/2 commands can be redirected 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) displaying one of six pre-defined grid systems,
(c) representing total dissolved solids by circular areas, and (d)
plotting the sample mean and standard deviation of the cation and anion
data, and the average total dissolved solids.
