绘制一个双倍数组序列，并在每次绘制后使用matplotlib刷新图形

import numpy as np
import matplotlib.pyplot as plt

sequence = np.array([])

def generate_sequence():
    global sequence
    if len(sequence) == 0:
        sequence = np.array([1])
    else:
        sequence = np.concatenate((sequence, sequence * 2))

plt.figure()

def plot_sequence():
    plt.clf()
    plt.plot(sequence)
    plt.xlabel('Index')
    plt.ylabel('Value')
    plt.title('Double Array Sequence')
    plt.grid(True)
    plt.pause(0.1)

for i in range(10):
    generate_sequence()
    plot_sequence()

import numpy as np
import matplotlib.pyplot as plt

sequence = np.array([])

def generate_sequence():
    global sequence
    if len(sequence) == 0:
        sequence = np.array([1])
    else:
        sequence = np.concatenate((sequence, sequence * 2))

plt.figure()

def plot_sequence():
    plt.clf()
    plt.plot(sequence)
    plt.xlabel('Index')
    plt.ylabel('Value')
    plt.title('Double Array Sequence')
    plt.grid(True)
    plt.pause(0.1)

for i in range(10):
    generate_sequence()
    plot_sequence()

plt.show()
