Thank you for your help.

More specific information about what you want is needed. "Figure" is relatively vague.

PROC PRINCOMP has a PLOTS= option that offers many different types of plots. See the documentation: https://documentation.sas.com/?docsetId=statug&docsetTarget=statug_princomp_syntax01.htm&docsetVersi... maybe one of the built in plots works for you

Thank you for responding me.

i need to perform a 2 dimension graphic representing the 2 principal component for individidual and for variables and the biplot graphic.

Thank you

I suspect you are looking for a "score plot" and a "loadings plots." See the article 

"How to interpret graphs in a principal component analysis"

which discusses these plots and how to create them from the output of PROC PRINCOMP.
