Hi,

The following code displays a figure with both a red and a blue arrow 
(generated by annotate). But the pdf that is saved only shows the red 
one. It seems that the line ax1.set_xscale('log') is causing the 
trouble, because if it is commented out, the blue arrow reappears in the 
pdf. Any hints?

import numpy as np
from matplotlib import pyplot as pp

fig = pp.figure()
ax2 = fig.add_subplot(111)
ax1 = ax2.twinx()
ax1.set_xlim(xmin=100,xmax=10000)
ax1.set_ylim(ymin=-60, ymax=5)
ax1.set_xscale('log')
ax2.set_xlim(xmin=100,xmax=10000)
ax2.set_ylim(ymin=-5,ymax=35)
ax2.set_xscale('log')

ax1.annotate("", (10000,-30), (2000,-30),
              arrowprops=dict(arrowstyle="-|>",fc="b", ec="b"))
ax2.annotate("", (100, 5), (2000, 5),
              arrowprops=dict(arrowstyle="-|>",fc="r", ec="r"))
pp.savefig('test_arrow.pdf')
pp.show()
