以下是相关代码的工作版本(至少需要 2011-11-14 的 Matplotlib 1.1.0 版本):
Here's the working version of the code in question (requires at least version Matplotlib 1.1.0 from 2011-11-14):
import numpy as np
import matplotlib.pyplot as plt
plt.axis([0, 10, 0, 1])
for i in range(10):
y = np.random.random()
plt.scatter(i, y)
plt.pause(0.05)
plt.show()
注意对 plt.pause(0.05)
的调用,它会绘制新数据并运行 GUI 的事件循环(允许鼠标交互).
Note the call to plt.pause(0.05)
, which both draws the new data and runs the GUI's event loop (allowing for mouse interaction).
