The set of available Line2D markers and scatter markers has always been slightly different. Some features (such as mathtext markers) were only available in one place and not the other. This refactors everything into a new module which is used from everywhere else to keep the functionality consistent and equally capable everywhere.

This seems to pass all regression tests and doesn't change any relevant examples, but it's pretty core functionality, so care should be taken it doesn't break anything.

Mike, I'm curious: what is the effect of the two changes here?

This makes the markers more accurately align over the line drawn underneath.

The change to degrees was not intentional. @jdh2358, @efiring: What do you guys think? Do you think the angle of the scatter marker should stay in radians (as it always was)?

Personally, in general I would be in favour of using degrees throughout. There are a couple of reasons for this:

  • Easier to work with for less mathematically minded
  • Quicker to type for the more mathematically minded. i.e. np.pi/2 vs 90
  • Degrees suffers less with floating point precision issues (this is a bit of a moot point)
