[英]How to rotate a subplot in matplotlib freely
我目前正在編寫一個程序,可以在我的計算機屏幕上投影全息視頻,我編寫了下面的代碼,但我不知道如何專門旋轉子圖,我創建了一個 3*3 子圖,我需要旋轉子圖4 x 270 順時針,子圖 6 x 90 順時針和子圖 8 x 180。
第二個問題是如何去掉所有的軸 label... 這樣投影出來的全息圖會很好很整齊....
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)
我可能已經找到了一個解決方案,但不是一個完美的解決方案,我使用數學而不是代碼來旋轉繪圖,只需將其乘以負值以在 x 和 y 軸上翻轉,我還添加了降噪器 function 以降低偏差,這是我使用的代碼,如果有人對如何自由旋轉子圖有任何想法,請啟發我。
