防止标签文本重叠Matplotlib Python中的线图

Question

我尝试绘制由X_TN，Y_TN列表协调为（x，y）的线，并以系列顺序标记为Seri列表。我的简化代码如下所示。但是，标签已与我的线路重叠，例如（1）和（6）。如何让我的标签一般躲避行？谢谢。

import matplotlib.pyplot as plt
plt.style.use('seaborn-whitegrid')
import numpy as np

x_tn = [0,1,1,2,3,2,2]
y_tn = [0,0,1,2,1,1,0]
seri = [0,1,2,3,4,5,6]

plt.title("Function") 
plt.xlabel("x") 
plt.ylabel("y")

plt.plot(x_tn, y_tn, '-ok')

for x,y,k in zip(x_tn,y_tn,seri):

    label = f"({k})"

    plt.annotate(label, # this is the text
        (x,y), # these are the coordinates to position the label
        textcoords="offset points", # how to position the text
        xytext=(0,10), # distance from text to points (x,y)
        ha='center') # horizontal alignment can be left, right or center

#specify axis tick step sizes
plt.xticks(np.arange(min(x_tn), max(x_tn)+1, 1))
plt.yticks(np.arange(min(y_tn), max(y_tn)+1, 1))
    
plt.show()

Answer 1

xytext=(7,10), # distance from text to points (x,y)

通过此代码更改标签位置
