v4.6.0

[4.6.0] - 2025-03-03

Added

• Grouping plots:

  • ggbunch() function: combining plots with custom layout.

    See example notebook.

  • Support for plot title, subtitle, caption, margins and insets in gggrid() and ggbunch().

• Geometries:

  • geom_hex() [#556].

    See: example notebook.

  • Parameters width_unit and height_unit in geom_errorbar(), geom_boxplot(), geom_crossbar(), geom_tile() and geom_hex() [#1288]:

    See example notebook.

  • Parameters start and direction in geom_pie() [#1280].

    See example notebook.

• Texts and labels:

  • hjust and vjust parameters for axis labels [#1227],[#1230].

    See: example notebook.

  • multiline support for axis labels [#948].

    See: example notebook.

  • Markdown support for plot title, subtitle, caption, and axis labels [#1256].

    See example notebook.

• In the nudge position adjustment -
  the ability to specify absolute shift values for nudge:

  • unit parameter in position_nudge().

  • nudge_unit parameter in geom_text() and geom_label()

    See example notebook.

• Theme:

  • Parameters legend_ticks and legend_ticks_length for fine-grained control over colorbar tick marks [#1262].

    See: example notebook.

• Parameter spacer in image_matrix() function.

• transparent/blank/'' color [#1281].

Changed

• [DEPRECATED] class GGBunch is deprecated. Please use ggbunch() function instead.
• Axis breaks: changed default lower_exp_bound to -7 and upper_exp_bound to 6 (same as in theme(...)).
• Axis labels: changed default justification for rotated labels.
• Axis labels: changed orientation of automatic vertical labels.
• [BREAKING] geoms tile, bin2d, contour, contourf, density2d, density2df : default coordinate system changed from 'fixed' to 'cartesian'.
• [BREAKING] tiles in geom_bin2d() are sized according to the binwidth value, not the maximum possible.
• [BREAKING] only Lets-Plot/JS users: signature of "buildPlotFromXXX" functions changed, see current Kotlin/JS declarations:
  • buildPlotFromRawSpecs()
  • buildPlotFromProcessedSpecs()
• [BREAKING] Maven artifacts (doesn't affect Python users):
  • artifacts platf-awt, platf-batik, platf-jfx-swing are no longer published with a "-jvm" suffix.
    Before, these artifacts could be used in dependencies either with or without the "-jvm" suffix. Now only without suffix.
  • artifact "org.jetbrains.lets-plot:deprecated-in-v4-jvm" is removed.

Fixed

• Incorrectly rendered Area chart [#1295].
• Tooltip should not cover and hide the geometry that it provides info for [#1275].
• General purpose scale_continuous: can't use the expand parameter [#1285].
• Error when using stat='summary' if the data contains NaN values [#1301].
• Broken plot_background in gggrid [#1124].
• plot_background not inheriting from rect [#1278]
• gggrid: allow title and other labels for the entire figure [#715].
• ggbunch: overall title [#321].
• Expand discrete axis according to tile size with geom_tile [#1284].
• geom_bin2d implodes when the disparity in axes units is large [#1303].
• Livemap: parameters nudge_x and nudge_y have no effect on geom_text or geom_label [#1048].
• Livemap: Add zooming-in for geom_text()/geom_label() [#1059].
