Marginal Means plot for the Fixed Effects of a Repeated Measures ANOVA

Hello! Is there any way to create an means plot with a repeated measures design with prox mixed like so? A manually produced categorical line plot would work as well. I also tried manually making a line plot with sgplot and changing the tick labels in to categories with no luck. Here is what I am going for:

Here is a snippet of my data:

Here is my code so far:

The code did not produce the intended plot. Once again, a small example of line plot with categories on the x axis would work, and I could go from there! Thanks ahead of time!

Change title and move to stats community.

What would you recommend as a title change? Also, as soon as I figure out
how to move posts, I will!

There are at least two different ways to go about this. First would be to use the results of your STORE statement, and in the PROC PLM statements include an EFFECTPLOT statement. Second would be to change to PROC GLIMMIX and use a plots=meanplots option in the LSMEANS statement. This is more direct and is also available in PROC PLM (so you would not have to recode your PROC MIXED into PROC GLIMMIX, as you already have a store).
