闪烁以使图形更平滑

Question

我试图用scipy使我的图更平滑，但结果是一条水平线。

代码：

import numpy as np
import matplotlib.pyplot as plt
from scipy.interpolate import spline
dd = [1.0, 0.7071067811865476, 0.5, 0.3535533905932738, 0.25, 0.1767766952966369]
y = range(0,6)
dd1 = np.array(dd)
y1 = np.array(y)
xsmooth = np.linspace (dd1.max(),dd1.min(),5)
ysmooth = spline (dd1,y1,xsmooth)
plt.plot(xsmooth ,ysmooth)
plt.show()

提前感谢

我认为您可能在代码中混淆了x和y。如果dd是y值，y则是x值，则可以执行如下样条插值：

import numpy as np
import matplotlib.pyplot as plt
from scipy.interpolate import spline
y = [1.0, 0.7071067811865476, 0.5, 0.3535533905932738, 0.25, 0.1767766952966369]
x = range(0,6)
y = np.array(y)
x = np.array(x)
xsmooth = np.linspace (x.min(),x.max(),20) # an x vector with more intermediate values
ysmooth = spline(x,y,xsmooth) 
plt.plot(xsmooth ,ysmooth)
plt.plot(x,y,'o')
plt.show()
