v4.2.0

[4.2.0] - 2023-12-28

Added

• Support for Categoricals:

  • Support for pandas.Categorical data type [#914].
  • The levels parameter in as_discrete() function [#931].

  See: example notebook.

• Support for superscript for numbers in scientific notation [#743].

  Warning!

  Do NOT(!) use exponent_format='pow' if you are planning to export plot to a raster format (PNG,PDF).

  The CairoSVG library (which is under the hood of our ggsave() function) does not handre tspan element properly end breaks superscript notation when transforming SVG to PNG/PDF.

  More details: Kozea/CairoSVG#317
  See: example notebook.

• Support exporting plot to a file-like object.
  
  Convenience methods: to_svg(), to_html(), to_png(), to_pdf() [#885], [#590].

  See: example notebook.

• Sharing of X,Y-scale limits between subplots in gggrid() [#718].

  See: example notebook.

• geom_spoke() [#738].

  See: example notebook.

• scale_x_log2(), scale_y_log2() [#922].

• High-contrast tileset "BW" for geom_livemap().

  See: example notebook.

• New variables computed by 'count' and 'count2d' statistics: '..sumprop..', '..sumpct..' [#936].

  See: example notebook.

• Support using dictionaries for breaks/labels/values customization in scale_xxx() functions [#169], [#882].

  See: example notebook.

• The lablim parameter in scale_xxx() functions [#939, #946].

  See: example notebook.

• label_text parameter in theme() for annotation text settings [#930].

  See: example notebook.

• NumberFormat: new flag ~ to trim trailing zeros.

Changed

• [BREAKING] Function margin() is deprecated and will be removed in future releases.
  
  Please replace all existing usages, i.e. theme(plot_margin=margin(..)) and element_text(margin=margin(..))
  
  with a list or with just a number:

  • a number or list of one number - the same margin it applied to all four sides;
  • a list of two numbers - the first margin applies to the top and bottom, the second - to the left and right;
  • a list of three numbers - the first margin applies to the top, the second - to the right and left,
    the third - to the bottom;
  • a list of four numbers - the margins are applied to the top, right, bottom and left in that order.

  See: example notebook.

• Upgraded Apache Batik to version 1.17 [#887]

Fixed

• Jitter reproducibility in geom_jitter, position_jitter, position_jitterdodge [#911].
• Facets: order = 0 doesn't work as expected [#923].
• geom_livemap: fix missing styles (e.g. road outline on high zooms) [#926].
• geom_livemap: freeze at zoom 10 [#892].
• Enormous CPU / Time/ Memory consumption on some data [#932].

v4.1.0rc1

Updated version v4.1.0rc1

v4.0.1

[4.0.1] - 2023-09-13

Added

• plot_message parameter in theme(...) [#863].
  See: example notebook.

• Add geom_count()/stat_sum() [#821].
  See: example notebook.

Changed

• If layer transparency is set via the alpha-channel in the colors RGBA specification and via the alpha aesthetic,
  then the alpha aesthetic overrides the alpha-channel in the color. Previousely it was the opposite.

• geom_pie() defaults:

  • "stroke" is visible and stroke_side='both' (was stroke_side='outer').
  • the "hole" is not created automatically when stroke_side = 'both'/'inner' (was created automatically).

• geom_bar() now has solid outline color by default (was transparent).

• geom_tile(), geom_bin2d() now have solid outline color by default (was transparent).

  • however, by default the size is 0 (i.e. tiles outline initially is not visible).

Fixed

• geom_tile(), geom_bin2d() : the alpha aesthetic is applied to the tiles outline.
• scale_x_datetime(): error building plot for early dates [#346].
• geom_livemap(): theme/flavor plot background is not shown [#857].
• geom_livemap(): in AWT dragging a map in a facet moves maps in all facets.
• geom_livemap(): support rectangle 'linetype' [#307].
• theme_void() + flavor_xxx(): no expected plot background [#858].
• Inconsistent color in legend when using paint_a/paint_b/paint_c [#867].

[4.0.0] - 2023-08-17

Added

• Flavor-aware colors: pen, brush and paper

  • By default, all geometries utilize new flavor-aware colors.
  • Theme geom parameter allows redefinition of "geom colors": theme(geom=element_geom(pen, brush,paper)).

  See: example notebook.

• stat_summary() :
  example notebook.

• stat_summary_bin() :
  example notebook.

• stat_ecdf() :
  example notebook.

• geom_function() :
  example notebook.

• theme_void() [#830] :
  example notebook.

  example notebook.

• "boxplot_outlier" statistic: example notebook.

• Support for variadic line width and/or color in geom_line() and geom_path() [#313].

  example notebook.

• In tooltip customization API:
  disable_splitting() function [LPK-189].

  example notebook.

• In geom_pie():

  • stroke and color aesthetics - the width and color of pie sector arcs.
  • stroke_side parameter - which arcs to show (inner, outer, both).
  • spacer_width and spacer_color parameters - lines between sectors.

  See: example notebook.

  • size_unit parameter : example notebook.

Changed

• The default qualitative color palette is now Color Brewer "Set1" (was "Set2")

• Geometries default colors are now flavor-dependent: example notebook.

• Geometries default size/line-width is now slightly bigger.

• Point size is adjusted to match the width of a line of the same "size".

• [BREAKING] geom_pie() no longer supports parameter stroke_color.

• [BREAKING] geom_boxplot() no longer support parameter sampling.

• [BREAKING] geom_pointrange(): size aesthetic shouldn't affect line width [#751]:

  linewidth aesthetic is used for line width, size - for mid-point size only.

• geom_boxplot(): size and stroke parameters now affect outlier shapes.

• [BREAKING, only affects users of Lets-Plot Kotlin API]
  The entire project has undergone package refactoring.
  As a result of package names changed, Lets-Plot v4.0.0 is partially incompatible
  with Lets-Plot Kotlin API versions 4.4.1 and earlier.

Fixed

• ggsave() doesn't save geom_raster() layer to a file [#778].
• ggsave(): saving geomImshow() to SVG produces fuzzy picture [LPK-188].
• ggsave(): saving geomImshow() to raster format produces fuzzy picture.
• geom_crossbar() aesthetics take middle argument instead of y [#804].
• geom_boxplot() doesn't apply alpha to outliers [#754].
• geom_boxplot() outliers do not show tooltips.

• geom_ribbon(): not all tooltips are shown on a multi-layer plot [#847].
• Bug in empty plot: IndexOutOfBoundsException [#194].
• Weird tooltip/legend in case of extremely long value [#315].
• panning on interactive map should be more responsive [#336].

Changed

    of position_jitter() function;
  • nudge_x, nudge_y parameters of geom_text(), geom_label() have priority over x, y parameters
    of position_nudge() function.
