Quiver vectors superimposed on a plot

Question

I would like to plot y vs x line, then on top of it I would like to plot vectors. I can do this using plot and quiver functions of matplotlib. However, the vectors will always be drawn behind the line, not on top. That is the line will be visible over the vector arrows.

My question for all of you is... is there a way to put the quiver vectors on top of the previously plotted line?

Answer 1

You need to set the zorder of the quiver to be higher than the line.

x = range(15)
y = rand(15)
u = rand(15)
v = rand(15)

figure()
plot(x,y,'rx-',zorder=0)
quiver(x,y,u,v,zorder=1)
