Win7SP1

ActivePython-2.7.1.3-win32-x86

matplotlib-1.0.1.win32-py2.7 from sourceforge

I met the following with my dataset:

Save emf Error: too many values to uppack

Save pdf Error: Path lacks initial MOVETO

S ave eps: No Erro ,but cann’t open it.

Here is the code and dataset in ps files:

import cPickle

import matplotlib.pyplot as plt

from matplotlib import pylab

if name == “main”:

f = file(“downloadlist”,“rb”)

downloadlist = cPickle.load(f)

f = file(“uploadlist”,“rb”)

uploadlist = cPickle.load(f)

if( len(downloadlist) != len(uploadlist) ):

raise ImportError,"wrong type "

myaxis = plt.gca()

myaxis.loglog([],[],linestyle=‘None’)

myaxis.scatter(downloadlist,uploadlist,marker=‘x’)

plt.xlim( 10,pow(10,7) )

plt.ylim( 10,pow(10,8) )

plt.show()
