如何在matplotlib中自由旋转子图？

Question

我目前正在写一个程序，可以在电脑屏幕上投影全息视频，我曾写过下面的代码，我不知道如何具体旋转子图，我曾创建了一个3*3的子图，我需要将子图4顺时针旋转270，子图6顺时针旋转90，子图8旋转180。

第二个问题是如何去掉所有的轴标签... ... 这样投射出来的全息图就会很好看，很整齐...。

import pandas as pd
import serial 
import numpy as np
import matplotlib.pyplot as plt

ser = serial.Serial("COM5", 115200) # define the serial port that we are communicating to and also the baud rate
plt.style.use('dark_background')    #define the black background
plt.ion()                        # tell pyplot we need live data
fig,[[ax1,ax2,ax3],[ax4,ax5,ax6],[ax7,ax8,ax9]] = plt.subplots(3,3)     # plotting a figure with 9 subplot


Xplot = []
Yplot = []
Zplot = []
blankx = []
blanky = []
fig = [ax1,ax2,ax3,ax4,ax5,ax6,ax7,ax8,ax9]


while True:                         #always looping this sequence
    while(ser.inWaiting()==0):      #if no input from the serial, wait and do nothing
        pass
    data = ser.readline()           #obtain the input from COM 5 
    data_processed = data.decode('utf-8')  #to get rid of the unnecessary string part
    data_split = data_processed.split(",")  # split the incoming string into a list
    x = float(data_split[0])    #to obtain seperate float values for x,y,z
    y = float(data_split[1])
    z = float(data_split[2])
    reset = int(data_split[3])  # reset will output 1
    draw = int(data_split[4])   # draw will output 2

    if(draw == 2):
        Xplot.append(x)         #if draw is given instruction, add the x,y,z value into the list to be plot on the graph
        Yplot.append(y)
        Zplot.append(z)


    ax1.plot(blankx,blanky)         # subplotting
    ax2.plot(Xplot,Yplot,"ro")
    ax3.plot(blankx,blank)
    ax4.plot(Xplot,Yplot,"ro")
    ax5.plot(blankx,blank)
    ax6.plot(Xplot,Yplot,"ro")
    ax7.plot(blankx,blanky)
    ax8.plot(Xplot,Yplot,"ro")
    ax9.plot(blankx,blanky)

    if(reset == 1):
        for f in fig:       #if reset is given instruction, clear all figure and clear the elements in the plotting list
        f.clear()
        Xplot = []
        Yplot = []
        Zplot = [] 

    plt.pause(.000001)

我可能找到了一个解决方法，但不是很完美，我用数学而不是代码来旋转绘制，只是将它乘以负值在x轴和y轴处翻转，我还加了一个去噪函数来降低偏差，这是我使用的代码，如果谁有什么想法，如何自由旋转一个子图，请赐教。
