v0.3.3

(2017-08-30)

https://zenodo.org/badge/DOI/10.5281/zenodo.854777.svg

API Changes

  • Added crayon_palette(), a palette that selects from 163 named colors.

  • Added cubehelix_pal(), a function that creates a continuous palette from the cubehelix system.

  • Fixed bug where a color palette would raise an exception when passed a single scalar value instead of a list-like.

  • extended_breaks() and mpl_breaks() now return a single break if the limits are equal. Previous, one run into an Overflow and the other returned a sequence filled with n of the same limit.

https://zenodo.org/badge/DOI/10.5281/zenodo.260331.svg
  • Fixed bug in censor() where a sequence of values with an irregular index would lead to an exception.

  • Fixed boundary issues due internal loss of precision in ported function seq().

  • Added mizani.breaks.extended_breaks() which computes breaks using a modified version of Wilkinson's tick algorithm.

  • Changed the default function mizani.transforms.trans.breaks_() used by mizani.transforms.trans to compute breaks from mizani.breaks.mpl_breaks() to mizani.breaks.extended_breaks().

  • mizani.breaks.timedelta_breaks() now uses mizani.breaks.extended_breaks() internally instead of mizani.breaks.mpl_breaks().

  • Added manual palette function mizani.palettes.manual_pal().
