from scipy import interpolate
import numpy as np

import matplotlib.font_manager as mpt
zhfont=mpt.FontProperties(fname=r'C:/Windows/Fonts/msyh.ttc') #显示中文字体
#导入数据
filepath = r'D:projectideaideaProjectFlinkProjectsrcmainjavacomsfitutilsresult.csv'
x = np.loadtxt(filepath,dtype="str",delimiter=',',usecols=(0),encoding='utf-8')
print(x)

y = np.loadtxt(filepath,dtype="int",delimiter=',',usecols=(1),encoding='utf-8')
print(y)

plt.plot(x, y)
plt.show()

运行结果如下：
