.add_patch（）基本文件问题

Question

在我编写的代码中，.add_patch（）给出错误。过去5天一直试图解决这个问题，但不能这样做。 当我单独将其用于椭圆形而不是将其与另一个椭圆相结合时，也可以使用相同的呼叫。 请看一下！

# Importing Necessary Libraries
import pandas as pd
import numpy as np
import random as rd
import matplotlib.pyplot as plt
import matplotlib.patches as patches
import matplotlib.style as stl

xys = [[10,125],[100,26],[25,66],[67,1],[74,10]]
xys=np.array(xys)

mean = np.mean(xys,0)
stdDev = np.std(xys,0)

ellipse = patches.Ellipse(mean[0],mean[1],stdDev[0]*2,stdDev[1]*2)

fig, graph=plt.subplots()
graph.scatter(xys[:,0],xys[:,1])
graph.scatter(mean[0],mean[1])
graph.add_patch(ellipse)

这是我在运行文件时在终端上获得的结果

查看

In [ ]: patches.Ellipse?
Init signature: patches.Ellipse(xy, width, height, angle=0, **kwargs)
Docstring:      A scale-free ellipse.
Init docstring:
Parameters
----------
xy : (float, float)
    xy coordinates of ellipse centre.
width : float
    Total length (diameter) of horizontal axis.
height : float
    Total length (diameter) of vertical axis.
angle : float, default: 0
    Rotation in degrees anti-clockwise.

所以是：

ellipse = patches.Ellipse(
    xy=(mean[0], mean[1]),
    width=std[0] * 2,
    height=std[1] * 2
)
