I'm going to go ahead and merge this in to keep the ball rolling, but eventually:

• these methods could benefit from XML docs
• I intend to shift methods out of ScottPlot.Tools and into more descriptive namespaces if possible (Triaged Tasks and Features (Feb 2021) #716)

axes with non-decimal radixes has been removed

Thanks for noting this! I dropped a lot of functionality that added complexity to the tick system in an effort to make it easier to refactor a few months ago. An overhaul of the tick module is still a medium-term goal (#716), and I intend to add support for non-decimal radixes back in and add support other advanced features at that time.
