[pstricks] Simulated random walks and Brownian motions

[John Harris]

Hi all,

I am relatively new to PSTricks and would greatly appreciate some help trying to draw simulated random walks and Brownian motions. Presumably if I could do a random walk then scaling down the step size would produce a passable Brownian motion but I have not been able to get anything to work so far.

Any hints anyone has would be great thanks.

Cheers,
John Harris.
