I want to vouch for Matplotlib, I can see it gets a bad reputation when compared to these new shiny frameworks like plotly, but it's vastly more powerful. If you are a researcher and you want to publish in B&W (something still very common in fields like Physics and Astrophysics), no other plotting library for Python comes near. You can choose filling patterns, line patterns, annotate with LaTeX, etc. And, although hard, you can make your final product look as polished and perfect as you want (and as you are willing to take the time). No other library for Python comes near in these aspects. There are simpler tools and it's easy to get a good enough looking plot, but if you want to get that perfect one exactly as you need, there's no way around Matplotlib (at least amongst the well known Python plotting libraries).
