使用FuncAnimation在matplotlib动画的等值线图 [英] Animating a contour plot in matplotlib using FuncAnimation

问题描述

我试图创造matplotlib动画，更新三位艺术家，包括imshow，轮廓和文字。使用FuncAnimation我能够更新文本和图像组件，但一直没能更新等值线。具体来说，我想这是我的回调：

I am trying to create an animation in matplotlib that updates three artists, including imshow, contour and text. Using FuncAnimation I am able to update the text and the image components, but have not been able to update the contour. Specifically, I tried this as my callback:

def updatefig(*args):
    text_component.set_text(newText())
    image_component.set_array(newArrayData())
    contour_component.set_array(newArrayData())
    return [text_component,image_component,contour_component]

这code没有引发异常，但它也不更新等高线。我不知道这是早晚的事情我不知道，如果有更多的权利setter方法​​。谁能告诉我，如果这是可能的？

This code doesn't raise an exception but neither does it update the contour lines. I wonder if this is just a matter my not knowing the right setter method of if there is more to it. Can anyone tell me if this is possible?

谢谢，
礼

推荐答案

我didn't全面了解您的code（也因为它是不完整的），我想，而评论你的问题比回答吧.. （但我没有足够的声誉，能够做到这一点！）

I didn´t full understand your code (also because it is not complete) and I would like rather to comment your question than answering it... (but I don't have enough reputation to be able to do it!)

反正...我认为这个问题可能与轮廓本身，它返回不是一个艺术家有关，但QuadContourSet实例！你觉得这可能是什么问题？我有类似的东西ArtistAnimation ...

Anyway... I think the problem might be related with the contour itself, which returns not an Artist, but a QuadContourSet instance! Do you think this might be the problem? I had something similar with the ArtistAnimation...

如果这一点，你必须的冲QuadContourSet，直到它像一个
艺术家......我能解决我的问题，在链接的所有信息！

If this is the point, you have to "punch the QuadContourSet until it behaves like an Artist"... I could solve my problem with all the information in the link!

祝你好运！
