Lets Plot Versions Save

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

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

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).

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.

"sum" statistic [#821]: 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.

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.

geom_lollipop().

See: example notebook.

Aesthetic stroke [#320] and its scales scale_stroke(), scale_stroke_identity().

See: example notebook.

Aesthetic linewidth (for geom_lollipop()) and its scales scale_linewidth(), scale_linewidth_identity().

See: example notebook.

The 'newline' character (\n) now works as line break in legend text ([#726])

See: example notebook.

Horizontal error bars and vertical "dodge" ([#735]).

See: example notebook.

Colorbar in geom_imshow(). Parameters show_legend and color_by [#717].

[BREAKING] geom_dotplot() and geom_ydotplot() no longer support parameter stat.

Position adjustment settings:

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

geom_text(), geom_label() use stat='identity' by default.

JVM/Batik: improved "paint manager" which now has better performance and fixes issues with artifacts that could appear beyond the plot component.

gggrid() function.

See: example notebook.

joint_plot()

See: example notebook.

Export to PNG files in ggsave().

Note: export to PNG file requires the CairoSVG library.

See: example notebook.

Axis position parameter in position scales scale_x_*(), scale_y_*().

See: example notebook.

angle parameter in element_text() in theme().

See: example notebook.

Additional "color" aesthetics: paint_a, paint_b, paint_c.

These aesthetics are flexible and can be used as either "color" or "fill" as needed. See Multiple Color Scales demo.

Also added a set of related "color scale" functions with the "aesthetic" parameter for configuring of additional color scales.

See New "Scale" Functions demo.

Drawing quantile lines and filling quantile areas in geom_violin() and geom_density()

See: example notebook.

geodesic parameter for geom_segment() and geom_path().

See: example notebook.

density2d and density2df geometry types in residual_plot().

The MinGW toolchain is no longer required for installing of Lets-Plot on Windows.

[BREAKING] geom_violin() no longer supports parameter draw_quantiles. Use new quantile_lines and quantiles parameters as needed.

[BREAKING] stack and fill position adjustments now stack objects on top of each other only if these objects belong to different groups. If necessary, use mode="all"" in position_stack() or position_fill() to stack objects regardless of their group.

See: example notebook.

Python wheel for Python 3.11.

residual_plot().

See: example notebook.

geom_area_ridges().

See: example notebook.

geom_pie().

See: example notebook.

Annotations for pie chart:

See: example notebook.

New variables computed by 'count' and 'count2d' statistics: '..sum..', '..prop..', '..proppct..'.

See: example notebook.

Maps:

• "Spatial pies" on interactive maps.

  See: example notebook.

• The flat parameter for geom_path() and geom_segment() (replaces the retired geodesic parameter in geom_livemap).

  See: example notebook.

Static maps:

• The value "provided" for use_crs parameter.

  See: example notebook.

geom_imshow():

• Improved performance by orders of magnitude.

• Transparency of NaN values in grayscale images [#631]. See: example notebook.

• alpha parameter [#630]. See: example notebook.

tails_cutoff parameter in geom_violin() See: example notebook.
