v0.6.0

This release has many changes, check out the changelog. A version of the changes is included below.

---

API Changes

• The draw parameter of geom_map has been removed. Shapefiles should contain only one type of geometry and that is the geometry that is drawn.

• Ordinal (Ordered categorical) columns are now mapped to ordinal scales. This creates different plots.

• The default mapping for the computed aesthetic size of stat_sum has changed to 'stat(n)'. This also changes the default plot for geom_count.

New Features

• geom_text gained the adjust_text parameter, and can now repel text.
• Added annotation_logticks.
• Added geom_sina
• Added scales for ordinal (ordered categorical) columns.
• geom_step gained the option mid for the direction parameter. The steps are taken mid-way between adjacent x values.
• Added annotation_stripes.

Bug Fixes

• Fixed bug where facetting would fail if done on a plot with annotation(s) and one of the facetting columns was also a variable in the environment.

• Fixed bug where coord_flip would not flip geoms created by geom_rug (GH216).

• Fixed bug where plots with theme_xkcd cannot be saved twice (GH199)

• Fixed bug that made it impossible to map to columns with the same name as a calculated columns of the stat. (GH234)

• Fixed bug in geom_smooth that made it difficult to use it with stats other than stat_smooth. (GH242)

• Fixed bug in position_dodge where by bar plot could get thinner when facetting and useing preserve = 'single'. (GH224)

• Fixed bug in coord_trans where if the transformation reversed the original limits, the order in which the data was laid out remained unchanged. (GH253)

• Fixed bug in stat_count where float weights were rounded and lead to a wrong plot. (GH260)

• Fixed bug where one could not use the British spelling colour to rename a color scale. (GH264)

• Fixed bug in lims, xlim, and ylim where datetime and timedelta limits resulted in an error.

• Fixed bug where geom_rect could not be used with coord_trans. (GH256)

• Fixed bug where using free scales with facetting and flipping the coordinate axes could give unexpected results. (GH286)

• Fixed unwanted tick along the axis for versions of Matplotlib >= 3.1.0.

• Fixed geom_text not to error when using hjust and vjust. (GH287)

• Fixed bug where geom_abline geom_hline and geom_vline could give wrong results when used with coord_trans.

• Fixed bug where layers with only infinite values would lead to an exception if they were the first layer encountered when choosing a scale.

Enhancements

• Legends are now plotted in a predictable order which dedends on how the plot is constructed.

• The spokes drawn by geom_spoke can now have a fixed angle.

• Aesthetics that share a scale (e.g. color and fill can have the same scale) get different guides if mapped to different columns.

• When the transform of a specialised (one that is not and identity scale) continuous scale is altered, the user is warned about a possible error in what they expect. (GH254, GH255)

• The method_args parameter in stat_smooth can now differentiate between arguments for initialising and those for fitting the smoothing model.

• position_nudge can now deal with more geoms e.g. geom_boxplot.

• The limits parameter of scale_x_discrete and scale_y_discrete can now be a function.

• The width of the boxplot can now be set irrespective of the stat.

• The mid-point color of scale_color_distiller now matches that of the trainned data.

• The way in which layers are created has been refactored to give packages that that extend plotnine more flexibility in manipulating the layers.

• You can now specify one sided limits for coordinates. e.g. coord_cartesian(limits=(None, 10)).

• All the themeables have been lifted into the definition of theme so they can be suggested autocomplete.
