HI all
I am having 21 columns, 1st column as time, 2nd column to last column different depths (10m to 105m with 5m interval).
Now I want to plot current vectors as follows.
Any help will be appreciated.
thank you in advance..

Phanindra, use a quiver plot:
t = 0:10;
d = 0:10;
[T,D] = meshgrid(t,d); % create grid out of x- and y-vectors
Vt = sin(T).*sin(D); % data vector: x-component
Vd = cos(T).^2; % data vector: y-component
quiver(T,D,Vt,Vd)
xlabel('time')
ylabel('depth')

excellent answer Mr.Kim,
Thank you so much..
till this day I was very confused with the meshgrid and quiver command you made it very very easy.. thank you..

Hello Mr. Kim,
Once I tried to use your example of quiver plot, it gave me this result: (image attached)
What should I do to generate an exact quiver plot as questioned (with time series on x-axis, several layers of depth on y-axis, and vectors on certain layers of depth)?
Furthermore, if the data is loaded from a text file which consist of: - column 1: time (dd/mm HH:MM) - column 2: depth - column 3: vector u - column 4: vector v
Thank you
