There was a problem hiding this comment.
pep8 is complaining about one too few new lines here.

@efiring Is this worth back-porting to the color-overhaul branch? |

Yes, I think it is worth backporting. I've never been 100% sure what procedure to use for this; is it OK to simply cherry-pick the commit to the appropriate branch locally, and then push to github? Is that the way you have been doing it? |

That is what I have been doing on the premise that if I can merge someone elses PR to this branch it's kosher to merge it to an other branch. I'll take care of moving this one over. |

For the same reason as Quiver in matplotlib#4250.

The bug was revealed when a user was plotting to successive subplots inside a loop iterating through a numerical integration. U and V were references to objects that were updated inside the loop, but the figure was not drawn until the end. Therefore all panels showed the quiver of the last iteration.
