plotnine v0.7.1 Release Notes

Release Date: 2020-08-05 // almost 3 years ago

  • 🛠 v0.7.1 is a small bugfix and maintenance release. See the official changelog for details. A copy of the changes is also copied below.

    🐛 Bug Fixes

    • 🛠 Fixed issue where a plot has no data and the geoms have no data, but the mappings are valid. (404)
    • Fixed preserve='single' in plotnine.positions.position_dodge and plotnine.positions.position_dodge2 to work for geoms that only
      have x aesthetic and not xmin and xmax e.g plotnine.geoms.geom_text.
    • 🛠 Fix regression in v0.7.0 where plots with a colorbar would fail if using ~plotnine.themes.theme_matplotlib.

Previous changes from v0.7.0

  • 🚀 This is a large release with many bug fixes and enhancements. See offical changelog. A version of the changes is included below.]

    API Changes

    Changed the default method of caculating bandwidth for all stats that use kernel density estimation. The affected stats are stat_density, stat_ydensity, and stat_sina. These stats can now work with groups that have a single unique value.

    Changed plotnine.scale.scale_colour_continuous to refer to the same scale as plotnine.scale.scale_color_continuous.

    Changed plotnine.scale.scale_color_cmap so the parameter cmap_name refers to the name of the color palette and name refers to the name of the scale. (GH371)

    🆕 New Features

    aes got an internal function reorder which makes it easy to change the ordering of a discrete variable according to some other variable/column.

    stat_smooth can now use formulae for linear models.

    🐛 Bug Fixes

    Fixed issue where a wrong warning could be issued about changing the transform of a specialised scale. It mostly affected the timedelta scale.

    Fixed plotnine.geoms.geom_violin and other geoms when used with position='dodge' not to crash when if a layer has an empty group of data.

    Fixed bug in plotnine.geoms.geom_path for some cases when groups had less than 2 points. (GH319)

    🛠 Fixed all stats that compute kernel density estimates to work when all the data points are the same. (GH317)

    🛠 Fixed issue where setting the group to a string value i.e. group='string' outside aes() failed due to an error.

    🛠 Fixed issue where discrete position scales could not deal with fewer limits than those present in the data. (GH342)

    Fixed issue with using custom tuple linetypes with plotnine.scales.scale_linetype_manual. (GH352)

    Fixed plotnine.geoms.geom_map to work with facets. (GH359)

    🛠 Fixed plotnine.position.jitter_dodge to work when color is used as an aesthetic. (GH372)

    Fixed plotnine.geoms.geom_qq to work with facets (GH379)

    🛠 Fixed skewed head in plotnine.geoms.arrow when drawn on facetted plot (GH388)

    Fixed issue with plotnine.stats.stat_density where weights could not be used with a gaussian model. (GH392)

    Fixed bug where guide_colorbar width and height could not be controlled by legend_key_width and legend_key_height. (GH360)

    ✨ Enhancements

    You can now set the bandwidth parameter bw of stat_ydensity.

    Parameters ha and va of geom_text have been converted to aesthetics. You can now map to them. (GH325)

    All themes (except theme_matplotlib) now do not show minor ticks. (GH348)
