PROC SGPLOT provides a simple way to make a variety of scatter plots. This example is taken from Example 50.4 of
Chapter 50,
The LOESS Procedure.
The following statements create a SAS data set that contains information about differences in ocean pressure over time:
data ENSO;
input Pressure @@;
Year = _n_ / 12;
datalines;
12.9 11.3 10.6 11.2 10.9 7.5 7.7 11.7
... more lines ...
;
The following statements create a scatter plot of points along with a penalized B-spline fit to the data and produce Figure 21.36:
proc sgplot data=enso noautolegend;
title 'Atmospheric Pressure Differences Between '
'Easter Island and Darwin, Australia';
pbspline y=pressure x=year;
run;

Penalized B-Spline Fit with PROC SGPLOT
See
Chapter 91,
The TRANSREG Procedure,
for more information about penalized B-splines. Also see the section Grouped Scatter Plot with PROC SGPLOT and Figure 21.12 for an example of a scatter plot with groups of observations.
