I am new to matplotlib, and I don\'t know what the name of the title bar arrowed in following image is.
Title bar
I googled and dug from matplotlib official docu
The title bar of the figure may be called See How do I set custom CSS for my IPython/IHaskell/Jupyter Notebook? for how to apply this potentially to any notebook by default. An alternative is to not use the dialog-titlebar
judging from its name in the layout. It is a display: none;
property via CSS. Somewhere in your notebook you may state
%%html
%matplotlib notebook
backend, but %matplotlib widget
instead. This is part of jupyter-matplotlib and currently needs to be installed separately as shown in the link. It'll by default have no titlebar while still providing full interactivity. There is a looong term plan to have it replace the %matplotlib notebook
backend - but "looong" has many "o"s here.
