我運行下面的代碼在Python 2,直接從該站點採取:matplotlib條形圖例如不匹配網站
http://matplotlib.org/examples/api/barchart_demo.html
import numpy as np
import matplotlib.pyplot as plt
%matplotlib inline
N = 5
men_means = (20, 35, 30, 35, 27)
men_std = (2, 3, 4, 1, 2)
ind = np.arange(N) # the x locations for the groups
width = 0.35 # the width of the bars
fig, ax = plt.subplots()
rects1 = ax.bar(ind, men_means, width, color='r', yerr=men_std)
women_means = (25, 32, 34, 20, 25)
women_std = (3, 5, 2, 3, 3)
rects2 = ax.bar(ind + width, women_means, width, color='y', yerr=women_std)
# add some text for labels, title and axes ticks
ax.set_ylabel('Scores')
ax.set_title('Scores by group and gender')
ax.set_xticks(ind + width/2)
ax.set_xticklabels(('G1', 'G2', 'G3', 'G4', 'G5'))
ax.legend((rects1[0], rects2[0]), ('Men', 'Women'))
def autolabel(rects):
"""
Attach a text label above each bar displaying its height
"""
for rect in rects:
height = rect.get_height()
ax.text(rect.get_x() + rect.get_width()/2., 1.05*height,
'%d' % int(height),
ha='center', va='bottom')
autolabel(rects1)
autolabel(rects2)
plt.show()
令人奇怪的是,當這個顯示第一杆對應到「G1」顯示觸摸Y軸的邊緣,而不是它在網站上顯示的方式。
我有與其他條形圖相同的問題即時通訊創建如此試圖瞭解如何我可以空間欄 - 基本上留下任何一方的保證金。
