我有两本字典,其价值是人数...
d_1={1947: 1, 1950: 1, 1951: 2, 1955: 2, 1956: 1, 1957: 2, 1958: 2, 1959: 3, 1960: 1....}
d_2={1936: 1, 1945: 1, 1948: 2, 1949: 1, 1950: 2, 1951: 2, 1952: 3, 1953: 1, 1954: 41..}
我想创建显示人数的条形图。 X轴在year形成。
当我使用此代码格式时,除堆叠的条形外几乎相同。我希望将它们分开。如何解决?
import matplotlib.pyplot as plt
import numpy as np
import matplotlib.pyplot as plt; plt.rcdefaults()
x1=[t for t in d_1.keys()]
y1=[k for k in d_1.values()]
x2=[m for m in d_2.keys()]
y2=[n for n in d_2.values()]
fig, ax = plt.subplots()
index = np.arange(len(years_without_duplicates))
#list which has the years without duplicates
bar_width = 0.35
rects1 = plt.bar(x1, y1, bar_width,color='b')
rects2 = plt.bar(x2, y2, bar_width, color='r')
plt.xlabel('Years')
plt.ylabel('number of people')
plt.xticks([i for i in range(min(years_without_duplicates),max(years_without_duplicates)+1)],rotation=80,fontsize=6)
plt.legend()
plt.tight_layout()
plt.show()
最佳答案
只需移动酒吧:
bar_width = 0.35
x1 = [t - bar_width / 2 for t in d_1.keys()]
y1 = [k for k in d_1.values()]
x2 = [m + bar_width / 2 for m in d_2.keys()]
y2 = [n for n in d_2.values()]
