You can use the SGSCATTER procedure to produce scatter plot matrices. The following step creates a scatter plot matrix from
all the numeric variables in the Class
data set (available in the Sashelp
library) and produces FigureĀ 21.77:
proc sgscatter data=sashelp.class; matrix _numeric_ / diagonal=(kernel histogram); run;
The diagonal cells of FigureĀ 21.77 contain a histogram and a kernel density fit. The off-diagonal cells contain all pairs of scatter plots.

The MATRIX statement creates a symmetric scatter plot matrix. Other statements are also available. The PLOT statement creates a panel that contains one or more individual scatter plots. The COMPARE statement creates a rectangular scatter plot matrix. Linear and nonlinear fits can be added, and you can request many graphical features by specifying options.
