Speed up plotting - Githubissues

It looks to take ~4.6s to plot a blank 2x2 grid of plots after pressing apply. Want to try and get that down, and then deal with delays with plotting data on top of it.

It looks like findChild is called a lot and uses a significant amount of times. Also, try and do everything to set up the plot, and then only draw it once, instead of after changing each option.
