How to create a curve which depicts the change in performance of 80 athletes over time in SPSS

#1
Hi guys! Fun to be onboard these amazing forums. Hopefully forward in time I can give some help and not only be the recipient!

My question is regarding 4 datasets which all depicts the performance of 80 athletes (same people) over time. I would like to have advice on how to create a curve that shows the change over time in the athletes, and that has the standard deviation drawn around the line that depicts the mean value. What type of analysis in SPSS would be the best to use for this.

In essence I think its just to calculate the average value and standard deviation of each dataset and plot them, but if there is an easy way in SPSS where you can create the curve and see the SD nicely around the mean line it would be awesome.

thanks guys!
