Hi @unbelievetable , welcome to the Forum!
There’s currently a bug where qml.drawer.use_style is not working with the MPLDrawer (issue #8114 for future reference).
Fortunately there’s an easy workaround! Instead of using use_style you can call the style directly: qml.drawer.style._black_white() . You can use other styles too by just using style and adding an underscore before the name of the style.
So, to summarize, qml.drawer.use_style('black_white') doesn’t work, but qml.drawer.style._black_white() does work.
There’s a longer discussion on this issue and drawing options in Forum thread #8897 in case you want to take a look!
Let me know if this solves your issue!
