using proc corr i can calculate a correlation matrix between multiple factors,
but i have a data set and i want to plot a heat map correlation matrix where range of colors differ continuously according to the correlation that varies between -1 and 1.

here's one example using PROC CORR (Example 20.10 Correlation and Covariance Matrices
SAS/STAT(R) 9.3 User's Guide ) and here's another example using GTL discussed in this blog post How to build a correlations matrix heat map with SAS - The SAS Dummy
