Improve performance of MatPlotLib using Blitting #28
Description
The way it's currently set up, every time the user interacts with the plot it's entirely redrawn. For a very large resolution, this is prohibitive. The time rescaling is a good way to reduce the resolution, but the code should ideally support high ones.
Whilst switching away from MatPlotLib to Plotly Dash as per #19 would be ideal, in the interim the front-end could be modified to make use of MatPlotLib's 'Blitting' feature that makes it so the graph is only redrawn on demand. This has a bunch of overhead to set up and complicated resizing etc., though.
It would probably be less work than rebooking into Plotly, but Plotly is better in the long run.
