Scree plot size in proc princomp or proc factor

Vic3 — Thu, 19 Dec 2019 21:29:49 GMT

When I do PCA analysis the scree plot comes out 5 pages long with a lot of wasted space.

The usual: "ods graphics on / width=4in height=3in" does not seem to have any effect.

Any suggestions to re-scale the scree plot, make it shorter?

Thank you.

Show us your SAS code. Please click on the running man icon and then paste the code (as text) into the Window that appears.

ods graphics on / width=4in height=4in;
proc factor data=mydata corr scree ev method = principal;
var var1 var2 var3 var4 var5 var6 var7 var8;
run;
ods graphics off;

Regardless of width or height the scree plot does not change, prints several pages long.

This minor modification of your code works for me

proc factor data=mydata corr plots=scree ev method = principal;
