Graph correlations and confidence limits stored by the command ^z_r^
------------------------------------------------------------------

                           graph_options]


Description
-----------

^z_rplt^ draws dot charts portraying arbitrary subsets of the correlation and
confidence limit matrices created previously by the command ^z_r^, and currently
stored in the matrices S_1 and S_2. ^varlist^ is any subset of the variables rep-
resented in matrices S_1 and S_2, specified in any order.  By default, a dot
chart is drawn for each pair of variables in varlist and displayed in a triang-
ular form resembling a correlation matrix; see option ^column()^.  A dot chart
consists of 20 dots (at |r| = 0.1, 0.2,..., 1.0), the character `+' (at r = 0),
a line extending from lower to upper confidence limit, and a plotted symbol at
the value of the sample correlation coefficient.


Options
-------

^column(cvarlist)^ produces a rectangular array of dot charts, whose rows corres-
    pond to the variables in ^varlist^, and whose columns correspond to the vari-
    ables in ^cvarlist^; cvarlist is any subset of the variables represented in
    matrices S_1 and S_2.

^pen(penspec)^ specifies up to 3 pens for drawing the elements of the dotcharts.
    pen(abc) assigns pen a to the sample correlation coefficient, pen b to the
    line representing the confidence interval, and pen c to the dots that form
    the pseudo-axis of the dot chart. The default is pen(231).

^symbol (symspec)^ chooses a plot symbol for the sample correlation coefficient.
    symspec is any single character in `OTSopd.i'. The default is symbol(d).

graph_options are any of the options allowed with graph, twoway, except that
    the following are preempted:  connect, noaxis, xlabel, ylabel, yreverse.


Examples
--------

 . ^z_rplt height weight age systolic hrate^
   (10 dot charts, displayed as a triangular array, portraying correlations and
   their confidence limits, for all pairs of the variables height, weight, age,
   systolic, and hrate)

 . ^z_rplt height weight systolic hrate, col(age pct_fat) sym(o)^
   (8 dot charts, displayed as a rectangular array, portraying correlations and
   their confidence limits, between each of the variables height, weight, sys-
   tolic, hrate and each of the variables age and pct_fat; each of the 8 corre-
   lation coefficients is plotted as a small `o'.)
