.SH DESCRIPTION

\fBmultidist\fR is similar to
#set FILE = "../doc/prefab_dist.html"
#set TAG = "dist"
#include link
except that it can produce multiple, overlaid frequency distributions,
each from a separate data field (column).
Except as noted below, all of the
#set FILE = "../doc/prefab_dist.html"
#set TAG = "dist"
#include link
parameters may be used, and \fBmultidist\fR was contributed as
a backwards-compatible replacement for 
#set FILE = "../doc/prefab_dist.html"
#set TAG = "dist."
#include link

.SH PARAMETERS
    
.IP
\fBoverlay\fR may be given as \fCyes\fR, which causes multiple distributions
to be done.  Each field (column) of the data will be tabulated individually and a distribution
computed and plotted.  The first row of the data gives the name for each category,
and is used in the legend.  
\fBfld\fR should \fBnot\fR be supplied.  \fBxrange\fR and \fByrange\fR must be supplied.
If \fBoverlay\fR is not \fCyes\fR, multidist operates identically to 
#set FILE = "../doc/prefab_dist.html"
#set TAG = "dist prefab"
#include link
    
.IP
\fBrotate\fR may be given as \fCyes\fR to rotate the data matrix (as seen in
the above example).

.IP
#set FILE = "../doc/prefab_dist.html"
#set TAG = "All of the dist parameters"
#include link
are also supported.
