Hi All,
I'm trying to make a simple errorbar plot which gets saved to an EPS file. I
paste the code below. For some weird reason, the savefig line causes a
segmentation fault in ghostscript. when I use (in this case, on my computer)
206 points or more. It doesn't happen if I comment the "pl.rc('text',
usetex=True)" line out nor does it happen if I comment the pl.savefig line
out. This happens in matplotlib 0.99 and 0.98.5.2. Any help will be greatly
appreciated.
Regards,
Ewald Zietsman
#test.py
import matplotlib.pyplot as pl
import numpy as np
pl.rc('text', usetex=True)
pl.rc('font', family='serif')
N = 206
x1 = np.linspace(-10,10,N)
e1 = np.random.randn(N)
pl.errorbar(x1, x1, yerr=e1, fmt='k.')
pl.savefig('test.eps')
pl.show()
The error message:
python test.py
