I was using quiver to plot a vector field. The details of the code is not relevant here. As can be seen from the figure the vector [-21,-21] is pointing 45 from the positive horizonta when it should be in the reverse direction. Why?

I don't see your issue.
quiver(1.5, 1.5, -21, -21),axis([-20 20 -20 20])
