Gamma分布切断而不显示

Question

我制作了5个伽马图，最后一个，Gamma（100,7）被切掉了。使用相同的代码，我还制作了5个伽玛图（Gamma（128,8），Gamma（150,9），Gamma（169,10），Gamma（184,11），Gamma（205,12））并且没有他们出现了。我该如何解决这个问题？

import scipy.stats as stats 
from matplotlib import pyplot as plt

x = np.linspace (0, 100, 200) 
y1 = stats.gamma.pdf(x, a=29, loc=3) #a is alpha, loc is beta
y2 = stats.gamma.pdf(x, a=45, loc=4) 
y3 = stats.gamma.pdf(x, a=65, loc=5) 
y4 = stats.gamma.pdf(x, a=80, loc=6) 
y5 = stats.gamma.pdf(x, a=100, loc=7) #CUT OFF
plt.plot(x, y1, "y-", label=(r'$\alpha=29, \beta=3$')) 
plt.plot(x, y2, "r-", label=(r'$\alpha=45, \beta=4$'))
plt.plot(x, y3, "g-", label=(r'$\alpha=65, \beta=5$'))
plt.plot(x, y4, "m-", label=(r'$\alpha=80, \beta=6$'))
plt.plot(x, y5, "c-", label=(r'$\alpha=100, \beta=7$'))

plt.ylim([0,0.08])
plt.xlim([0,150])
plt.show()
