real time scope display (simple script)

This is a very SIMPLE script which plots data in real time.

A friend of mine had problems doing just this so I thought it might help others too...

Basically in this script I create a random vector (a), define the sampling rate the vector was sampled with and define the scope time base.
The script runs displays the entire vector in a continuous display.

My friend needed it for a simulation she did and in which her professor demanded a "semi" real time display.
