say I have

 s= 0.604098184248020  0.642263089970519  3.73235669061904  0.147329697780077  0.238159152322172  0.0172071450520552  0.00180492811644228

the values for s are going to change each time my loop gets called. How do I plot them using semilogy() in which the x-axis is the number of values in s, this case the number is 7. And have it work so on the next call of semilogy in my loop it plots new values of s on the same figure.

See

doc hold

Set

hold on

after the first iteration and add the subsequent lines. You'll want to cycle the color to distinguish the lines (altho seems like maybe I saw one change in later versions is that the color property isn't reset with hold any longer???? You can check easily enough)...
