我从matplotlib下载了这个示例并进行了一些更改。
到目前为止,我已经绘制了一个条形图,其中应用于y轴的有4个不同的数组,而x轴上则是测量计数。现在我想绘制4个子图,每个子图对应一个数组。
我已经完成了以下步骤:
import numpy as np
import matplotlib.pyplot as plt
n= 6
m1 = (0.10,0.12,0.10,0.11,0.14,0.10)
m2=(0.21,0.21,0.20,0.22,0.20,0.21)
m3=(0.29,0.27,0.28,0.24,0.23,0.23)
m4=(0.41,0.39,0.35,0.37,0.41,0.40)
x=[1,2,3,4,5,6]
fig, ax = plt.subplots()
index = np.arange(n)
bar_width = 0.2
opacity = 0.4
error_config = {'ecolor': '0.3'}
r1 = ax.bar(index, m1, bar_width,
alpha=opacity,
color='b',
error_kw=error_config)
r2 = ax.bar(index + bar_width, m2, bar_width,
alpha=opacity,
color='r',
error_kw=error_config)
r3 = ax.bar(index + bar_width+ bar_width, m3, bar_width,
alpha=opacity,
color='y',
error_kw=error_config)
r4 = ax.bar(index + bar_width+ bar_width+ bar_width, m4, bar_width,
alpha=opacity,
color='c',
error_kw=error_config)
plt.xlabel('D')
plt.ylabel('Anz')
plt.title('Th')
f, ((ax1, ax2), (ax3, ax4)) = plt.subplots(2, 2, sharex='col', sharey='row')
ax1.plot(x,m1)
ax2.plot(x,m2)
ax3.plot(x,m3)
ax4.plot(x,m4)
plt.tight_layout()
plt.show()
为什么我不能只画出 "ax1.plot(x,r1) ax2.plot(x,r2) ...",尽管r1和r2被定义为条形图?我需要改变什么?
