[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
                • 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
                • https://github.com/matplotlib/matplotlib/pull/9801
                • General agreement locator
                • General agreement formatter:
                        • needs way to get old beghaviour
                        • useful for teaching/default
                • @Antony L suggested naming convention
                        • MPLxyDateFormatter
                        • Alias AutoFormatter to current MPLXYDateFormatter
                        • Document “We reserve right to change formatter”
                • deprecate old linear scalar formatter?
                • localization of month
                        • Check if way?
