我是Python的新手，正在为这个错误“x和y必须相同大小”而挣扎。

def plotNumericalConvergence(paramArr, GrArr, Label):
    
    plt.figure()
    
    x = paramArr
    y = GrArr

    plt.scatter(x=x,y=y)

    plt.xlabel(Label)
    plt.ylabel('Gr')
  
    plt.title('title')
    
    plt.show()

下面是它用来绘图的代码：

def numericalConvergence(Position, Velocity, Charge, Mass, dt, B):
    
    gyroArr = np.array([])
    gyroArr2 = np.array([])
    gyroArr3 = np.array([])
    dtArr = np.array([])
    fieldArr = np.array([])
    chargeArr = np.array([])
    
    dtArr = np.append(dtArr, [dt])
    gyroArr = np.append(gyroArr, [6.324555320336759])
    gyroArr2 = np.append(gyroArr, [6.324555320336759])
    gyroArr3 = np.append(gyroArr, [6.324555320336759])
    fieldArr = np.append(fieldArr, [[0,0,1]])
    chargeArr = np.append(chargeArr, Charge)
    
   # Incrementing timestep
    for i in range (10):
        start = time.time()
        
        dt = dt + 0.1000 

        print('\n'"Timestep", i+1)

        trv= pstep(qom,Position,Velocity,0.0,dt,N_t)
        Gr = MeasuredGr(trv)
        PredGr = GyroRadius(Position, Velocity, Charge, Mass, dt, B)

        gyroArr = np.append(gyroArr, [Gr])
        dtArr = np.append(dtArr, [dt])
        
        end = time.time()
        
        print("Predicted gyro radius =", PredGr)
        print("Measured gryo radius =", Gr)
        print("Timestep =", dt)
        print("Magnetic Field =", B)
        print("Charge =", Charge)
        print("nt =",(end - start)/dt) # need to fix this## Predicted gyro radius
        Label = "DT"
    plotNumericalConvergence(dtArr, gyroArr, Label)

    # Incrementing magnetic field
    for i in range (10):
        start = time.time()
        
        dt=0.001
        B = [float(x) + 1 for x in B] # Increments all numbers in magnetic field array by 1
        
        print('\n'"Magnetic Field", i+1)

        trv = pstep(qom,Position,Velocity,0.0,dt,N_t)
        Gr = MeasuredGr(trv)
        PredGr = GyroRadius(Position, Velocity, Charge, Mass, dt, B)

        gyroArr2 = np.append(gyroArr2, [Gr])
        fieldArr = np.append(fieldArr, [[B]])

        
        end = time.time()
        
        print("Predicted gyro radius =", PredGr)
        print("Measured gryo radius =", Gr)
        print("Timestep =", dt)
        print("Magnetic Field =", B)
        print("Charge =", Charge)
        print("nt =",(end - start)/dt)
        Label = "Magnetic Field"
        
    plotNumericalConvergence(fieldArr, gyroArr2, Label)

    # Incrementing Charge
    for i in range (10):
        start = time.time()
        
        B = [0,0,1]
        Charge = Charge + 0.1
        
        print('\n'"Charge", i+1)
        
        # add label param for y, new gr array each loop - no 2nd method needed

        trv=pstep(qom,Position,Velocity,0.0,dt,N_t)
        Gr = MeasuredGr(trv)
        PredGr = GyroRadius(Position, Velocity, Charge, Mass, dt, B)

        gyroArr3 = np.append(gyroArr3, [Gr])
        chargeArr = np.append(chargeArr, [Charge])
        
        print("Predicted gyro radius =", PredGr)
        print("Measured gryo radius =", Gr)
        print("Timestep =", dt)
        print("Magnetic Field =", B)
        print("Charge =", Charge)
        print("nt =",(end - start)/dt)
        Label = "Charge"
        
    print(gyroArr3)
    print(chargeArr)
    plotNumericalConvergence(chargeArr, gyroArr3, Label)

该图适用于dt，但不适用于磁场或电荷。我在这里看到了关于重塑数组的东西，以及沿着于[：，0]之类的东西，但我真的被卡住了，不能100%理解Python。谢谢！
