Matplotlib update plot in loop To update the plot on every iteration during the loop, we can use matplotlib. We constantly update the variables to be plotted by iterating in a loop and then plotting the changed values in Matplotlib to plot data in real-time or make an animation. We use ...
import matplotlib.pyplot as plt # 绘制图形 plt.plot([1, 2, 3, 4], [1, 4, 9, 16]) # 清除之前的绘图点 plt.cla() # 绘制新的图形 plt.plot([1, 2, 3], [1, 2, 3]) plt.show() 这两种方法可以根据具体需求选择使用。clf()函数会清除整个图形,包括轴和标签,而cla()函数只会清除轴...
