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=sqrt(dx**2+dy**2),
lw=0, overhang=.1)
But this is ugly. And when I zoom in the arrowsize isnt scaled with the
linewidth.
Any idea instead to switch to the pyx package?
By,
Friedrich
