st: Overlaying an unknown number of line graphs

Dear list,

I am writing a do file to take n random samplings from a distribution, for a user-inputted value of n. This file creates variables labelled sample`i' and freq`i' for each value of i between 1 and n. I would like to draw a single line graph with all of the plots of sample`i' against freq`i' overlaid on it.
So something like:
twoway (line freq1 sample1, sort) (line freq2 sample2, sort)...(line freqn samplen, sort) But I can't see how to write this without knowing the value of n beforehand, and then, if n is large, writing an incredibly long command.
Is there a way to do this within Stata?
