I've just tried this; unfortunately it still doesn't improve the resolution of my plot.
As I run the code, the terminal returns the info I've attached below. Is it possible to set the fixed resolution buffer before it completes the projection?
I feel like the issue here might be that the projection is getting completed to the default 800x800 resolution and so it is impossible to later improve this resolution - only reduce it.
It would be great to hear your thoughts on this?
