Hello,
I’m writing a script that removes data from plots by looping over axes.get_lines(), removing data, then using axes.set_lines(). It works quite well, but when it’s a plot with error bars, the vertical part of the error bar is not disappearing.
I’m assuming the vertical part is a vline or something and so should not be with the other lines. Where does this data get stuck? 
Thanks!

As described in the doc, the errorbar command creates lines and line
collections, where the errorbars are created as line collections.
Axes.collections contains the list of collection artist that belong to
the axes hence this is the place.
However, I don't think manipulating Axes.collections (and the return
value of get_lines() ) in this way is a good idea. All the artist
added to an axes has "remove" method. When called, the artist remove
itself from the axes it belongs.
I'm not sure what your intention is, but if you want to temporarily
remove some artists from the axes, it would be easier to make them
simply invisible. Otherwise, I recommend you to use the remove method.

Thanks JJ, I’ll give that a shot. The problem with making them invisible is they take up a lot of unnecessary overhead in my vector graphics program that already runs ridicuslow
