JMS, if you are talking about the vector field, use quiver. For labeling the graph you add lines (manually or in the code) and edit the properties to add arrows.

Hi Mischa Kim, Thanks for your reply. Firstly, I should asked how to get the first image without Arrows and then for the second one how? Do you know how I can color the vector field like the first image"Without arrows"? Then we can talk about the second one.
Many thanks!

so to get the image without the arrows i am going to assume you have the [x,y,u,v] that will be used in quiver. as you have x,y,u, and v coordinates you can calculate the magnitude of the vector for each x,y position using u and v. then use imagesc(x,y,m) where m is the magnitude of each vector.
