how to plot 1000 samples , one sample generating at i mili sec.

i hava data(voltage ) from which i want plot 1000 samples each generating at 1 mili second ,

if i use hist (data), i need those 1000 samples on x-axis , and the corresponding voltage values at y-axis or

using stem(data) does the same work what i need ?

hist and stem are not the same. hist command allows to represent distribution of data, but stem command is like plot with the difference that points are'nt joined. stem command is used to represent discret signal. Look at the difference when you have less data

close
t=0:10
y=abs(sin(100*t))
subplot(2,1,1);stem(t,y)
subplot(2,1,2),hist(y)
