我正在I使用%matplotlibplot命令在内联模式下使用IPython笔记本绘制NumPy值的数组plt.plot(I,'o').

结果输出是:

<matplotlib.figure.Figure at 0x119e6ead0>
Out[159]:
[<matplotlib.lines.Line2D at 0x11ac57090>,
 <matplotlib.lines.Line2D at 0x11ac57310>,
 <matplotlib.lines.Line2D at 0x11ac57510>,
 <matplotlib.lines.Line2D at 0x11ac57690>,
 <matplotlib.lines.Line2D at 0x11ac57810>,
 <matplotlib.lines.Line2D at 0x11ac57990>,
 <matplotlib.lines.Line2D at 0x11ac57b10>,
 ....
 ....
]

然后我的情节显示在这些输出线下方.

有没有办法只显示情节并隐藏<matplotlib.lines.Line2D at ...>输出？

我想在直方图中添加密度图.我对pdf函数有所了解,但我感到困惑,其他类似的问题也无济于事.

from scipy.stats import * 
from numpy import*
from matplotlib.pyplot import*
from random import*

nums = []
N = 100
for i in range(N):
    a = randint(0,9)
    nums.append(a)

bars= [0,1,2,3,4,5,6,7,8,9]
alpha, loc, beta=5, 100, 22

hist(nums,normed= True,bins = bars)


show()

我正在寻找这样的东西

我想制作熊猫系列的直方图（prior_fails），但我不断收到以下 ValueError：

ValueError: view limit minimum -36814.8560105 is less than 1 and is an 
invalid Matplotlib date value. This often happens if you pass a non-datetime 
value to an axis that has datetime units

这就是我调用直方图的方式

plt.hist(prior_fails)
plt.ylabel('Frequency')
plt.xlabel('Days of Failure (%)')

先前失败是具有以下索引的系列：

prior_fails.index
Out[85]: 
Index([u'prior110', u'prior113', u'prior118', u'prior141', u'prior144',
   u'prior16', u'prior217', u'prior223', u'prior245', u'prior29',
   u'prior352', u'prior360', u'prior370', u'prior438', u'prior55',
   u'prior59', u'prior60', u'prior68', u'prior74', u'prior88'],
  dtype='object')

和内容：
