.SH DESCRIPTION

\fBmultidist\fR is similar to
.ig >>
<a href="../doc/prefab_dist.html">
.>>
\0dist
.ig >>
</a>
.>>
except that it can produce multiple, overlaid frequency distributions,
each from a separate data field (column).
Except as noted below, all of the
.ig >>
<a href="../doc/prefab_dist.html">

\0dist
.ig >>
</a>
.>>
parameters may be used, and \fBmultidist\fR was contributed as
a backwards-compatible replacement for

.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

.IP
\fBrotate\fR may be given as \fCyes\fR to rotate the data matrix (as seen in
the above example).
