Dear all

I have the following script:

nulldata 100

series u = normal()

# just for comparability

u[1] = 0

series rwalk1 = cum(u)

series rwalk2 = 0

rwalk2 = rwalk2(-1) + u

# I want to visualize the graph on my screen. How should I proceed??

gnuplot rwalk1 rwalk2

#I stored the data in this file but I cannot display the data against time like a time series. What should I do?

store random walk.gdt rwalk1 rwalk2

Thank you in advance

Raul
