Python 绘制数据移动窗口
import numpy as np
win_size = 500 # 窗口大小为500
x_data = np.zeros(win_size)
y1_data = np.zeros(win_size)
y2_data = np.zeros(win_size)
y3_data = np.zeros(win_size)
...
def update_data():
# 只展示x轴数据平移过程，y轴同理
x_data[:-1] = x_data[1:] # 移动
x_data[-1] = new_value # 将新值写入
...
while True:
update_data()
