<STRONG>Description:</STRONG>
<UL>
<LI><TT>scatplt</TT> displays bivariate scatterplots and some statistical
summaries for PostScript display. The summary statistics are weighted,
except for the rank order (Spearman) correlation coefficient. </LI></UL>
<DT><IMG height=14 alt=o src="GSLIB Help SCATPLT.files/ball.red.gif" width=14>
<STRONG>Parameters:</STRONG>
<UL>
<LI><B>datafl:</B> The data file in a simplified Geo-EAS format.
<LI><B>icolx, icoly, icolwt</B> and <B>icol3vr:</B> The columns for the
<I>x</I> variable (horizontal axis), <I>y</I> variable (vertical axis),
weight (if less than or equal to zero then equal weighting is used;
otherwise, the weight is used to calculate the summary statistics), and
third variable (if less than or equal to zero then no third variable is
considered; otherwise, each bullet is gray scale coded according to this
third variable)
<LI><B>tmin</B> and <B>tmax:</B> all values strictly less than <B>tmin</B>
and strictly greater than <B>tmax</B> are ignored.
<LI><B>outfl:</B> file for PostScript output.
<LI><B>xmin, xmax</B> and <B>xlog:</B> minimum and maximum plotting limits
for the <I>x</I> axis. These do not have to be compatible with the trimming
limits. Pairs within the trimming limits, but outside the plotting limits,
are still used for computing the correlation coefficient. Setting
<B>xmin</B> greater than or equal to <B>xmax</B> will cause the program to
use the minimum and maximum data values encountered. If <B>xlog</B>=0 then
an arithmetic scaling of the <I>x</I> axis is used, <B>xlog</B>=1 then a
logarithmic scaling is used.
<LI><B>ymin, ymax</B> and <B>ylog:</B> minimum and maximum plotting limits
for the <I>y</I> axis. Setting <B>ymin</B> greater than or equal to
<B>ymax</B> will cause the program to use the minimum and maximum data
values encountered. If <B>ylog</B>=0 then an arithmetic scaling of the
<I>y</I> axis will be used, <B>ylog</B>=1 then a logarithmic scaling will be
used.
<LI><B>nthpoint:</B> plot every <B>nthpoint</B>'th data point. This should
normally be set to 1, however, it may be used to subset large data sets.
<LI><B>dotsiz:</B> size of the black dot marking each data (0.1 is small,
1.0 is the default, and 10 is big)
<LI><B>gmin</B> and <B>gmax:</B> minimum and maximum gray scale limits: used
if a third variable is considered to shade each data point
<LI><B>title:</B> a 40-character title for the top of the plot. A short
description of the program </LI></UL>

<STRONG>Application notes:</STRONG>
<UL>
<LI>If the scatterplot appears too erratic because of too few data, one may
consider smoothing.
<LI>The plot may become quite crowded if there are too many data pairs.
