我正在寻找方法或其他东西,这将允许我删除一个的东西(我知道cla()将清除整个),例如来自轴的行,类似于:
x = self.plt.plot([5*a,0],[0,5*b], color = 'black')
self.plt.draw()
#here I want to to remove x, calculate new position and draw again
一切都是以互动模式完成的。

>>> import matplotlib.pyplot as plt
>>> plt.ion()
>>> l,=plt.plot([1,2,3],[4,5,6],'bo-') # a figure pops up
>>> l.remove() # nothing happens
>>> plt.draw() # don't forget to redraw
>>>
但是,如果您只想更改元素,则可以使用set_ydata(...)
后跟draw()
。
