[4.8.0] - 2025-11-05

Added

  • Geometries:

    • geom_pointdensity() [#1370].

      See: example notebook.

    • Geoms with 1-to-1 statistics (such as geom_qq(), geom_sina()) preserve the mapping to original data after statistical transformation.

      See: example notebook.

    • geom_histogram(): custom bin bounds (parameter breaks) [#1382].

      See: example notebook.

  • Plot Layout:

    • The legend automatically wraps to prevent overlap - up to 15 rows for vertical legends and 5 columns for horizontal ones [#1235].

      See: example notebook.

    • gggrid(): support for shared legends (parameter guides).

      See: example notebook.

  • Plot Theme:

    • flavor_standard() sets the theme's default color scheme [#1277].

      Use to override other flavors or make defaults explicit.

      See: example notebook.

    • theme_gray() as an alias for theme_grey().

    • legend_justification parameter of theme() accepts additional string values: 'left', 'right', 'top', and 'bottom'.

      See: example notebook.

    • Support for inward axis ticks.

      See: example notebook.

  • Markdown:

    • Support for target attribute for links.
    • Links now open in a new tab by default [#1397].

  • ggtb(): size_zoomin and size_basis parameters for geometry scaling [#1369].

    See: example notebook.

Changed

  • [BREAKING] Explicit group aesthetic now overrides default grouping behavior instead of combining with it [#1401].

    See: example notebook.

Important

Previously, setting group='variable' would group by both the explicit variable AND any discrete
aesthetics (color, shape, etc.).
Now it groups ONLY by the explicit variable, matching ggplot2 behavior.
Use group=[var1, var2, ...] to group by multiple variables explicitly,
and group=[] to disable any grouping.

  • Missing values in geom_line(), geom_path(), geom_ribbon(), and geom_area() create gaps in geometries instead of being interpolated over [#818], [#1406].

    See: example notebook.

  • theme: the exponent_format default value changed to 'pow' - superscript powers of 10 (was e-notation).

  • The multi-layer line plot now shows tooltips for each series simultaneously, in the same way that a single-layer plot with color mapped to series does.

Fixed

  • geom_pie on geospatioal plot with map_join failes to render without explicit group aesthetic.
  • geom_density2d: NullPointerException when weight aesthetic contains None values [#1399].
  • Tooltip shows duplicate lines when as_discrete is applied twice to the same var [#1400].
  • geom_sina: incorrect shape in legend [#1403].
  • geom_density2d: Incorrect processing of weighted statistics when None value occurs in the x or y column.
  • facet_wrap: indescriptive error when the specified facet variable is not present in the dataset [#1409].
  • Integer numbers in facet strip titles are displayed as float [#1386].
  • Error when using scale_identity(aesthetic="shape") [#1212].
  • ggsave: theme option face="italic" doesn't work [#1391].
  • Fail early if string format is incorrect [#1410].
