Among them, the stacking graph in Chapter 5 uses the following source code to draw the graph, and the problem that the graph area deviates from the Y-axis appears as follows, which is very ugly.
import matplotlib.pyplot as plt
days = [1,2,3,4,5]
sleeping = [7,8,6,11,7]
eating = [2,3,4,3,2]
working = [7,8,7,2,2]
playing = [8,5,7,8,13]
plt.plot([],[],color='m', label='Sleeping', linewidth=5)
plt.plot([],[],color='c', label='Eating', linewidth=5)
plt.plot([],[],color='r', label='Working', linewidth=5)
plt.plot([],[],color='k', label='Playing', linewidth=5)
plt.stackplot(days, sleeping,eating,working,playing, colors=['m','c','r','k'])
plt.xlabel('x')
plt.ylabel('y')
plt.title('Interesting Graph\nCheck it out')
plt.legend()
plt.show()
Baidu found a solution: set the x, y coordinate range,
import matplotlib.pyplot as plt
# The following two lines of code are specially used to solve the problem of Chinese display
from pylab import *
mpl.rcParams ['font.sans-serif'] = ['Microsoft YaHei']
days = [1,2,3,4,5]
sleeping = [7,8,6,11,7]
eating = [2,3,4,3,2]
working = [7,8,7,2,2]
playing = [8,5,7,8,13]
# draw label legend
plt.plot([],[],color='m', label='Sleeping-睡觉', linewidth=5)
plt.plot([],[],color='c', label='Eating-吃饭', linewidth=5)
plt.plot([],[],color='r', label='Working', linewidth=5)
plt.plot([],[],color='k', label='Playing', linewidth=5)
plt.stackplot(days, sleeping,eating,working,playing, colors=['m','c','r','k'])
# Set the value range of the x and y axes to:
plt.ylim(0, 24)
plt.xlim(1, 5)
plt.xlabel('x-date')
plt.ylabel('y-item')
plt.title('Interesting Graph\nCheck it out')
# draw label legend
plt.legend()
plt.show()
Perfect solution!
