[Matplotlib-devel] Call Notes 26 Mar

[Jody Klymak]

Hi all,

Call notes are online at https://paper.dropbox.com/doc/Matplotlib-meeting-agenda-aAmENlkgepgsMeDZtlsYu

Folks are welcome to take a look and add items for next week’s agenda (if there is an Easter Monday meeting).  If the file doesn’t get too unwieldly, there was general agreement that Paper was a decent way to keep notes and an agenda, at least for now.

Cheers,   Jody

Notes: 26 Mar 2018

		• Antony, Hannah, Ryan, Jody
Ticks
		• issues with extra ticks outside viewlims.  Antony said they were due to roundoff errors.
		• maybe trim at Locator level. 
		• deprecate not visible:  
			• ticker.Locator would all need to change
			• deprecate out of range ticks first, and then expect proper list
			• epsilon out of viewlims?  Keep those.  
		• ticks and lines top and bottom: individual lines for each ticks.  
			• overhaul, single line for top and bottom ticks.  LineCollection for grids.
			• back compatibility?  Custom Axes subclass with new Axis subclass….
			• each line call is slow (units support).
			• speed benefit? 
			• can’t manipulate individual tick visibility.  
Datetime formatting:
		• https://github.com/matplotlib/matplotlib/pull/10841

			• useful for teaching/default
		• @Antony L suggested naming convention
