Python使用matplotlib,numpy,scipy进行散点的平滑曲线化方法

示例说明：绘制平滑曲线

代码：

import matplotlib.pyplot as plt  
import numpy as np  
from scipy.interpolate import spline  
  
T = np.array([6, 7, 8, 9, 10, 11, 12])  
power = np.array([1.53E+03, 5.92E+02, 2.04E+02, 7.24E+01, 2.72E+01, 1.10E+01, 4.70E+00])  
xnew = np.linspace(T.min(),T.max(),300) #300 represents number of points to make between T.min and T.max  
  
power_smooth = spline(T,power,xnew)  
  
plt.plot(xnew,power_smooth)  
plt.show()  

结果：
