Create Animated Scatter plot in 3d using matplotlib in python

[barry76]

Hello, with the reference link I am trying to plot a scatter graph for the sensor I am working with in 3d axis using animation package in matplotlib.

Mentioned below is the code I am

import numpy as np import matplotlib.pyplot as plt from mpl_toolkits.mplot3d import Axes3D import matplotlib.animation as animation import serial seru = serial.Serial('COM6', 115200) def update_lines(num): rmsX,rmsY,rmsZ = vib_sense() dx, dy, dz = np.meshgrid([[rmsX],[rmsY],[rmsZ]]) # replace this line with code to get data from serial line print(dx) #print(dy) #print(dz) text.set_text("{:d}: [{:.0f},{:.0f},{:.0f}]".format(num,rmsX,rmsY,rmsZ)) # for debugging x.append(rmsX) y.append(rmsY) z.append(rmsZ) graph._offsets3d = (x, y, z) return graph, def vib_sense(): while True: s = seru.read(54) if(s[0] == 126): if(s[15] == 127): if(s[22]== 8): rms_x = ((s[24]*65536)+(s[25]*256)+s[26])/1000 rms_y = ((s[27]*65536)+(s[28]*256)+s[29])/1000 rms_z = ((s[30]*65536)+(s[31]*256)+s[32])/1000 max_x = ((s[33]*65536)+(s[34]*256)+s[35])/1000 max_y = ((s[36]*65536)+(s[37]*256)+s[38])/1000 max_z = ((s[39]*65536)+(s[40]*256)+s[41])/1000 min_x = ((s[42]*65536)+(s[43]*256)+s[44])/1000 min_y = ((s[45]*65536)+(s[46]*256)+s[47])/1000 min_z = ((s[48]*65536)+(s[49]*256)+s[50])/1000 ctemp = ((s[51]*256)+s[52]) battery = ((s[18]*256)+s[19]) voltage = 0.00322*battery rmsValueX = 0; rmsValueY = 0; return rms_x,rms_y,rms_z x = [0] y = [0] z = [0] fig = plt.figure(figsize=(5, 5)) ax = fig.add_subplot(111, projection="3d") graph = ax.scatter(x, y, z, color='orange') text = fig.text(0, 1, "TEXT", va='top') # for debugging ax.set_xlim3d(-255, 255) ax.set_ylim3d(-255, 255) ax.set_zlim3d(-255, 255) # Creating the Animation object ani = animation.FuncAnimation(fig, update_lines, frames=200, interval=50, blit=False) plt.show()

Error

whenever I am trying to make this work my code is not responding properly and I guess the problem I am facing is under Update line function where I am not properly initializing the values

Any advice on this will be really grateful
