Question on plotting vector field

[rpaynter]

Hi
I am a college student and I have a homework assiment to model  
groundwater fluid flow. In this model we are to plot the vectors of  
the fluid flow. I can calculate the values of the vectors in excel but  
excel does not have the option of plotting a "vector field". So I was  
wondering if your program octave can plot a "vector field" and if so  
how?
Thank you
