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() -- Christopher Brown, Ph.D. Associate Research Professor Department of Speech and Hearing Science Arizona State University http://pal.asu.edu ------------------------------------------------------------------------------ AppSumo Presents a FREE Video for the SourceForge Community by Eric Ries, the creator of the Lean Startup Methodology on "Lean Startup Secrets Revealed."
