Description
I think this is happening because I am plotting a gaussian that is very narrow compared to the x range. Still it seems failing here is bad behavior.
here is some code that reproduces the problem, taken from IPython notebook:
%matplotlib inline
import matplotlib.pyplot as plt
from scipy.stats import norm as scipy_stats_norm
from math import sqrt
plt.clf()
fig, ax = plt.subplots()
max_x = 1100 # this fails
#max_x = 1000 # this works
x = np.linspace(-max_x, max_x, 300)
mean = -0.0938
stdev = sqrt(0.008812)
ax.plot(x, scipy_stats_norm.pdf(x, loc=mean, scale=stdev), color='red', linewidth=2)
ax.set_yticklabels([])
ax.set_xlim(-max_x, max_x)
filename = '/tmp/fail.png'
plt.savefig(filename, bbox_inches='tight')
plt.show()Here's the result:
