I met the following with my dataset:

Save emf Error: too many values to uppack

Save pdf Error: Path lacks initial MOVETO

Save eps: No Erro ,but cann't open it.

Here is the code :

import cPickle

import matplotlib.pyplot as plt

from matplotlib import pylab

if name == “main”:

x_list =[19373.599999999999, 11022.120000000003, 90037.820000000007, \

57023.05000000001, 54658.360000000001, 50667.520000000004,\

37177.82, 165244.79000000001, 2575.2399999999998, 2826.2399999999998]

y_list = [0.0, 1172.96, 83027.377499999988, 80505.191250000003, \

67571.089999999997, 16066.450000000001, 2806.2912500000002,\

108459.68750000004, 0.0, 5.0800000000000001]

myaxis = plt.gca()

myaxis.loglog([],[],linestyle=‘None’)

myaxis.scatter(x_list,y_list,marker=‘x’)

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

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

plt.show()

I can confirm this bug (at least for eps and pdf files) on the master branch as well. I have also found that it occurs even for ‘+’ markers and for ‘o’ markers. So, this problem isn’t limited to just the AsteriskPolygonCollections. It appears to be something wrong with respect to utilizing the log scales. If I try the same code, but without log scale, the images are valid.

Hong - just as a side note, using “loglog(, , linestyle=‘None’)” to force your graph into log scale is not the right way. It is better to do:

myaxis.set_xscale(‘log’)
myaxis.set_yscale(‘log’)

This won’t fix your problem, but at least it is better coding style.
