Re: Help on plot of collected sample data

Hi Michael and Duane,

Thanks for your help! I am sorry that I didn't
express what I want clearly. If I have a vector Y
whose length is M and plot(Y) gives one curve. That
is one set of sample data at time T0. Now we have the
sample data at T0...Tn. If I use a MxN matrix and
plot the figure, all N curves are stacked together.
Since the data was collected at different time, I want
them separate along one axis. I can?t use surf( ) function
because there should be no surface connection between
each curve.

I may make it even more confuse. In fact what I want
iss as follows:
Plot(rand(10,5)) gives 5 curves at X-Y plane. Now
I want to separate the 5 curves along the Z axis. Curve 1
is plotted on Z=0, curve 1 is plotted on Z=1,? and curve 5
is plotted on Z=5.

I thought it should be some function avaliable
in MATLAB, but after searching I didn't find it.


Thanks a lot for your help!

Regards,

Tao
