Since you say you’ve changed matplotlib versions, I assume you’ve seen the posts in the forums about the version mismatch between the unit tests and matplotlib. That still looks like the problem, however. If you’ll post a link to your repl.it or the code and error, not a screenshot, someone can probably diagnose your problem much more quickly.
