Axis label in PSM figure

[Helen20855]

I am learning how to use HEEMOD to develop partitioned survival model by following instruction at: https://cran.r-project.org/web/packages/heemod/vignettes/j_survival.html. When I scrolled down to the end of that page, I saw a figure to indicate membership over time. Since it's for PSM, should its x-axis label be time (or Model cycle) instead of Markov cycle? Also, shall y-axis label be survival instead of count? Should y-axis use 0-1 instead of 1000?
