Full Changelog: v3.0.1...v3.1.0

Version 3.0.1

Minor release to improve compatibility with the Python ecosystem and remove deprecation warnings. Thanks to Kian-Meng Ang for docs and instructions fixes, Maxime Liquet for CI and docs fixes, and to Jim Bednar for docs updates, compatibility fixes, and coordinating the release.

• Update to work with matplotlib=3.6 (#90)
• Fix holoviews opts deprecation warning (#94)
• Add support for Python 3.10 (#81)
• Remove windows 3.6 case from test suite due to lack of mamba support (#94)
• Remove Param dependency (#84)
• Improve installation instructions (#92)

Version 3.0.0

Major new release adding 23 new continuous colormaps from Peter Kovesi's upstream colorcet.m. The existing colormaps should all have the same names and values as in previous releases, and apart from a minor change to the type of Matplotlib categorical colormaps this release should be fully backwards compatible with previous releases.

Thanks to Randy Pittman for major improvements to the automated colormap definition code that allowed bringing in the new colormaps, to Maxime Liquet for CI and website fixes, and to Jim Bednar for docs updates, compatibility fixes, and coordinating the release.

New features:

• Added new upstream colormaps (#65):
  • Rainbow: rainbow_bgyr_10_90_c83 (called rainbow4, a much closer match to Jet's color range than rainbow while remaining perceptually uniform)
  • Linear: linear_kbgoy_20_95_c57 (called gouldian, an improved version of Matlab's parula colormap), linear_kbgyw_10_98_c63
  • Cyclic: circle_mgbm_67_c31, circle_mgbm_67_c31_s25, cyclic_bgrmb_35_70_c75, cyclic_bgrmb_35_70_c75_s25, cyclic_isoluminant, cyclic_mybm_20_100_c48, cyclic_mybm_20_100_c48_s25, cyclic_mygbm_50_90_c46, cyclic_mygbm_50_90_c46_s25, cyclic_rygcbmr_50_90_c64, cyclic_rygcbmr_50_90_c64_s25, cyclic_wrkbw_10_90_c43, cyclic_wrkbw_10_90_c43_s25, cyclic_ymcgy_60_90_c67, cyclic_ymcgy_60_90_c67_s25
  • Colorblind-safe: diverging_linear_protanopic_deuteranopic_bjy_57_89_c34, linear_protanopic_deuteranopic_kbw_5_95_c34, linear_protanopic_deuteranopic_kyw_5_95_c49, linear_tritanopic_kcw_5_95_c22, linear_tritanopic_krw_5_95_c46
• CI fixes and improvements, including testing for python 3.9 (#71, #72, #75, #77)
• Clarified docs to indicate that all maps have an original list-of-numeric-triples form, typically but not always with a long name, that all those starting with b_ are Bokeh colormaps in hex format, and that only the subset of shorter names that are aliases for longer names are Bokeh colormaps (as some other original list names like glasbey_bw just happen to be short (#79)

Compatibility:

• For categorical (Glasbey) maps, now uses a Matplotlib ListedColormap (with distinct colors) instead of a LinearSegmentedColormap (discrete approximation to a continuous map) (#79)

Version 2.0.5

Minor release primarily to update PyPI classifier to show that the license is not proprietary. Also added some docstrings and usage examples, and updated the swatch function to work with both list and tuple colormaps.

Version 2.0.2

Minor bugfix release; avoids registering Matplotlib colormaps twice.

Version 2.0.1

Minor bugfix release:

• Fixed palette_n and cm_n to contain only the human-meaningful short names, not the CET_ variants.
• Updated website

Version 2.0.0

Major release adding perceptually based categorical colormaps, complementing the previous perceptually based continuous colormaps:

• Added Glasbey 256-color categorical colormaps (#25)
• Adding new continuous colormaps from CET (#26)
• Added console script and docs to make it easy to run examples (#23)
• Added colormap plotting commands in plotting.py (#25)

Version 1.0.1

Infrastructure update:

• Added travis and appveyor
• Switched to using nbsite, pyct.build, pyctdev,

Docs update:

• Migrated README content to docs
• Added usage section

Full list of changes since the previous release: v1.0.0...v1.0.1

Version 1.0.0

Minor update improving compatibility and ease of use:

• Added attribute access for colormap and palette dictionaries for convenience (PR #5)
• Pulled out the subset of colormaps that have readable names into the cm_n and palette_n dictionaries to make it simpler to use them in GUI widgets selecting colormaps
• Improved Python2/Python3 compatibility, now supporting Python 2.7, 3.4, 3.5, and 3.6.

Minor backwards compatibility issue:

• Renamed inferno to bmy to avoid confusion with matplotlib.

Version 0.9.1

Bumped version because of incorrect github tag; no changes in functionality.
