在python matplotlib中鼠标悬停时X轴值不可见

我试图在X轴上绘制一些Y轴的值与时间的关系。一切正常，但当我将鼠标悬停在图形线上时，我只得到带有格式化标签的Y轴的值。我尝试了许多方法，但无法理解并实现在同一个悬停框中获取X轴的值

import time
from time import strftime
import matplotlib.pyplot as plt
import matplotlib.animation as animation
import random
from mpldatacursor import datacursor


fig = plt.figure()
ax = fig.add_subplot(1,1,1)
xs = []
ys = []

def animate(i,xs,ys):

    rand_list = []

    ###### Generate Two random input values ###### 

    for i in range(0,2):
        data_1 = random.uniform(0,1.2)
        rand_list.append(data_1)

####### Append the two random numbers in Y axis list ############
    ys.append(rand_list)


####### Append Current Time to the X-axis list ########

    xs.append(time.strftime('%X'))

    ax.clear()

#### Plotting the X and Y lists on the axes ###########

    plt.gcf().autofmt_xdate()
    plt.xticks(rotation=45)

    #datacursor(ax.plot(xs,ys,linestyle='-'),hover=True,formatter='Time:{}'.format(statement))


#################### This is the line where i am trying to format the label and get the value in hover box

    datacursor(ax.plot(xs,ys, linestyle='-'),hover=True, formatter='TGI Value: {y:.2f}'.format)
    
    plt.xlabel("Time")
    plt.ylabel("TGI Value")

ani = animation.FuncAnimation(fig, animate, fargs=(xs,ys), interval=10000)

### Display the graph #####
#plt.gcf().autofmt_xdate()
plt.show()

我已经在悬停框中实现了Y轴值。我现在需要在悬停框中实现X轴的时间值

这是当前图形，鼠标悬停时仅显示TGI值。需要X轴上显示的时间也在同一个悬停框中吗
