    See demos:

    • Magnifier Inset Effect.
    • Map of Kotlin Island with Inset.

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

• Geometries:

  • geomHex() [#556].

    See example notebook.

  • Parameters

    • widthUnit in geomErrorBar(), geomBoxplot(), geomCrossbar() [#1288].
    • widthUnit and heightUnit in geomTile() and geomHex().

    See example notebook.

  • Parameters start and direction in geomPie() [#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 positionNudge().
  • nudgeUnit parameter in geomText() and geomLabel()

  See example notebook.

• Theme:

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

    See: example notebook.

• Aliases for transparent color: "" (blank string), "blank" and "transparent" color [#1281].

Changed

• [DEPRECATED] class GGBunch is deprecated. Please use ggbunch() function instead.
• [BREAKING] The height parameter has been deprecated for the geomErrorBar.
• Axis breaks: the minimum distance between axis labels was reduced to avoid unsuitable layouts.
• 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 geomBin2d() are sized according to the binwidth value, not the maximum possible.
• [BREAKING] In Lets-Plot JS API v 4.6.0 (only Lets-Plot/JS users): signature of "buildPlotFromXXX" functions changed, see current Kotlin/JS declarations:
  • buildPlotFromRawSpecs()
  • buildPlotFromProcessedSpecs()
• [BREAKING] In Lets-Plot v 4.6.0, Maven artifacts:
  • 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 scaleContinuous: can't use the expand parameter [#1285].
• Error when using stat='summary' if the data contains NaN values [#1301].
• Broken plotBackground in gggrid [#1124].
• plotBackground 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 geomTile [#1284].
