I have a set of data that contains X and Y coordinates, in addition I have Vx and Vy at each X and Y coordinates, thus 4 variables and all of them are known (no equations or assumptions needed)
Is there anyway that I can draw a graph on a 2D plane showing the direction of the arrows of each Vx and Vy at each X and Y coordinates?
In other words, consider X and Y are a point (.) from that point an arrow should apper with direction on x called Vx and direction on y called Vy.

try this function:
quiver(X,Y,VX,Vy);
you can add this graph to the previously created graph by using hold on statement.
You may need to do some modifications on X and Y to be able to plot it
