Thanks for the report. We made a number of changes to the implementation of the Enable color traits in the most recent release, and although the Chaco tests passed with...

Sorry for the delay in looking at this. This seems like a worthwhile addition to the polygon plot. There's one major comment above about the way to compute the runs...

The `CalendarScaleSystem` has to deal with ticking ad various different resolutions (from years down to microseconds) which need different strategies for ticking, so there is no one `tick_interval` that works...

The context for how various Pyface classes and interfaces relate is documented here: https://docs.enthought.com/pyface/overview.html#pyface-concepts. One part of the problem is that `CallbackTimer` is a subclass of `PyfaceTimer`, and documenting that...

Also, I guess, is there lack of clarity here: https://docs.enthought.com/pyface/timer.html
