我有以下问题:
我在 matplotlib.pyplot 中使用 hist()
我正在尝试在同一张图上创建 4 个直方图。以及它们中每一个的近似高斯分布。
如何在同一张图上绘制 4 个直方图,而不让它们相互阻塞(并排)?有什么想法吗?
最佳答案
matplotlib documentation 中有几个示例.这个看起来可以回答您的问题:
import numpy as np
import pylab as P
#
# first create a single histogram
#
mu, sigma = 200, 25
x = mu + sigma*P.randn(10000)
#
# finally: make a multiple-histogram of data-sets with different length
#
x0 = mu + sigma*P.randn(10000)
x1 = mu + sigma*P.randn(7000)
x2 = mu + sigma*P.randn(3000)
# and exercise the weights option by arbitrarily giving the first half
# of each series only half the weight of the others:
w0 = np.ones_like(x0)
w0[:len(x0)/2] = 0.5
w1 = np.ones_like(x1)
w1[:len(x1)/2] = 0.5
w2 = np.ones_like(x2)
w0[:len(x2)/2] = 0.5
P.figure()
n, bins, patches = P.hist( [x0,x1,x2], 10, weights=[w0, w1, w2], histtype='bar')
P.show()
