plotting time discrete data

[leprechaun]

Hi everybody!

I have a vector of time-discrete data. How do I plot a one dimensional vector?
Is there an app that does the Job or a smart way?
Either simply dots at the sampled Points or a polyline (implied polyline would be great anyway)?

say M1:=[0,1,2,3,4,0,1,2,3,4,0,1,2,3,4]; is a sampled sawtooth where the index into the vector is supposed to be my sample index. No absolute time needed, just implied tn.
