It should behave like a marker: it should not resize when I zoom in.

Hello,
I want do add an arrow *tip* to a line with the same angle.
I have tried this:
from pylab import *
from matplotlib import collections, transforms
def MyArrow(ax, x, y, ang, scale=50, over=.5, color='k'):
ar = [(0,0), (-.5,-over), (0,1), (.5,-over), (0,0)]
col = collections.PolyCo
Hello,
the original problem that I have is to add an arrow to the end of a
plotted line. I tried this
from pylab import *
x=linspace(0, 1.85, 100)
y=sin(x)
dx=x[-1] - x[-2]
dy=y[-1] - y[-2]
plot(x,y,lw=2)
arrow(x[-2], y[-2], dx, dy,
width=.02,
length_includes_head=True,
head_length=s
