Call Notes 26 Mar

Hi all,

Call notes are online at

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:
    ? General agreement locator
    ? General agreement formatter:
      ? needs way to get old beghaviour
      ? useful for teaching/default
    ? @Antony L suggested naming convention

      ? Alias AutoFormatter to current MPLXYDateFormatter
      ? Document ?We reserve right to change formatter?
