I have the following program where I am trying to generate a pdf:
1 import matplotlib
2 matplotlib.use('AGG')
3 import matplotlib.pyplot as plt
4 import matplotlib.image as image
5 import matplotlib.gridspec as gridspec
6 from matplotlib.backends.backend_pdf import PdfPages
7 import numpy as np
8
9 np.random.seed(0)
10
11 x, y = np.random.randn(2, 100)
12
13 with PdfPages('wx_plot.pdf') as pdf:
14 fig, (ax1,ax2) = plt.subplots(nrows=2, figsize=(8,11))
15 gs = gridspec.GridSpec(2, 1,
16 height_ratios=[1.5,3]
17 )
18 ax1 = plt.subplot(gs[0])
19 ax1.xcorr(x, y, usevlines=True, maxlags=50, normed=True, lw=2)
20 ax1.grid(True)
21 ax1.axhline(0, color='black', lw=2)
22
23 ax2 = plt.subplot(gs[1])
24 ax2.acorr(x, usevlines=True, normed=True, maxlags=50, lw=2)
25 ax2.grid(True)
26 ax2.axhline(0, color='black', lw=2)
27 pdf.savefig('fig')
28 pdf.close()
When I run it I get the following error:
Traceback (most recent call last):
File "testinger.py", line 13, in <module>
with PdfPages('wx_plot.pdf') as pdf:
AttributeError: __exit__
What is going on here and how do I resolve this issue?
