v2.4.0

[2.4.0] - 2022-06-20

Added

• Python 3.10 support [#505].

• Python 3.9: a Python wheel for macOS arm64 architecture (Apple Silicon).

• LetsPlot.set_theme() - configuring a default plot theme.

  See: example notebook.

• Quantile-Quantile (Q-Q) plot:

  • geometries:
    • geom_qq()
    • geom_qq_line()
    • geom_qq2()
    • geom_qq2_line()
  • quick Q-Q : the qq_plot() function in the bistro module.

  See: example notebook.

• Marginal plots: the ggmarginal() function [#200],
  [#384].

  See: example notebook.

• Parameter orientation in geoms: bar, boxplot, density, histogram, freqpoly, smooth, violin.

  See: example notebook.

• New in plot theme:

  • face parameter in element_text().

    See: example notebook.

  • panel_border parameter in theme() [#542].

    See: example notebook.

  • Tooltip theme options, new parameters in theme():

    • tooltip - tooltip rectangle options;
    • tooltip_text, tooltip_title_text - tooltip text options;
    • axis_tooltip_text, axis_tooltip_text_x, axis_tooltip_text_y - axis tooltip text options.

    See: example notebook.

• scale_color_gradientn() and scale_fill_gradientn() functions [#504].

  See: example notebook.

Changed

• geom_livemap [breaking change] : symbol="point" now should be specified explicitly
  to enable the "livemap" layer to handle provided
  "point" aesthetics directly. This change doesn't affect "points" layers added via
  the geom_point() geometry layer.
• New style of tooltip color marker (two sidebars with a stroke color)
  and symbols in legend (rectangle with a stroke instead of a slash-line).
• New type of general tooltip for geom_boxplot: displayed under the cursor.
• Default sampling type for geom_violin switched from systematic to pick.

Fixed

• geom_livemap: support of the arrow parameter in geom_segment [#131].
• Differences in tooltip color marker for plots with and without livemap.
• Labels out of plot when axis_text_y='blank' [#525].
• NPE in corr_plot with null coefficients.
• Outliers are not shown when boxplot' alpha=0.
• Support for polars.DataFrame [#526].
• JFX rendering issue that causes tooltips to stuck [#539].
• Support trim parameter in density and ydensity stats [#62].
• Unexpected point geometries on geom_livemap() [#547].
• geom_violin: add missing parameters kernel, bw, adjust, n, fs_max to signature and docstring.
