Matplotlib-如何删除特定的线或曲线 [英] Matplotlib - How to remove a specific line or curve

问题描述

我想删除多条线图中的特定线.贝娄是一个给定的示例，对我来说还不够，因为它仅删除最后绘制的线条，而不删除我要删除的线条.我怎样才能做到这一点?如何在整个程序中寻址特定行(按名称，编号，参考)并删除该行?

I want to remove a specific line in a plot of multiple lines. Bellow is a given example which is not sufficient for me because it removes only the last plotted line and not the line that I want to remove. How can I do that? How can I address a specific line(by name, by number, by reference) throughout the program and delete that line?

self.axes.lines.remove(self.axes.lines[0])

推荐答案

几乎所有绘图功能都返回对在以下示例中创建的artist对象的引用:

Almost all of the plotting functions return a reference to the artist object created ex:

ln, = plot(x, y)  # plot actually returns a list of artists, hence the ,
im = imshow(Z)

如果您有参考文献，则可以通过remove (doc)函数，例如:

If you have the reference you can remove an artist via the remove (doc) function ex:

ln.remove()
im.remove()
