我有这个代码来显示一年与元素图,

import matplotlib.pyplot as plt

import pylab

import numpy as np

x = [0,0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,

1,1.1,1.2,1.3,1.4,1.5,1.6,1.7,1.8,1.9,

2,2.1,2.2,2.3,2.4,2.5,2.6,2.7,2.8,2.9,

3,3.1,3.2,3.3,3.4,3.5,3.6,3.7,3.8,3.9,

4,4.1,4.2,4.3,4.4,4.5,4.6,4.7,4.8,4.9,

5,5.1,5.2,5.3,5.4,5.5,5.6,5.7,5.8,5.9,

]

y = [190.70,118.90,98.30,45,20.01,6.60,54.20,200.70, 269.30,261.70,

225.10,159,76.40,53.40,39.9,15,22,66.8,132.90,150,

149.40,148,94.40,97.60,54.10,49.20,22.50,18.40,39.30, 131,

220.10, 218.90,198.90, 162.40,91, 60.50, 20.60, 14.80, 33.9,123,

211,191.80, 203.30, 133, 76.10, 44.9, 25.10, 11.6, 28.9, 88.30,

136.30, 173.90, 170.40, 163.60, 99.30 , 65.30, 45.80, 24.7, 12.6,4.20 ]

labels = ['1950', '1960', '1970', '1980', '1990','2000', '2010']

plt.xticks(x, labels, rotation='horizontal')

pylab.ylim(0, 250)

pylab.xlim(0, 6)

plt.yticks(np.linspace(0,250,6,endpoint=True))

plt.xticks(np.linspace(0,6,7,endpoint=True))

pylab.xlabel('YEAR')

pylab.ylabel('No. of sunspots')

pylab.title('SUNSPOT VS YEAR GRAPH')

plt.plot(x, y, 'ro')

plt.show()

代码的输出是这样的：

我想要显示的是折线图,而不仅仅是点
