Show percentage of variance covered by each factor in proc factor

I ran a proc factor method as shown below:

proc factor data=work.final_data scree r=varimax method=principal;
run;

This generated a scree plot along with the general proc factor report with factor number on the x-axis and eigen values on the y-axis. Is it possible to generate a scree plot with a y-axis showing the percentage variance covered by each principal component (which is a factor in that case since method=principal)?

Replace the SCREE option with the option PLOTS=SCREE. Be sure that ODS Graphics is on. If not, add this statement before your PROC FACTOR step.

ods graphics on;

Use an option in the ODS GRAPHICS statement. For example,

ods graphics / height=960px;
