v2.3.0

[2.3.0] - 2022-03-21

Added

• Plot subtitle and caption [#417]:
  subtitle parameter in ggtitle() and labs(),
  caption parameter in labs(),
  plot_subtitle and plot_caption parameters in theme().

  See: example notebook.

• The 'newline' character (\n) now works as line break in plot title, subtitle, caption and in legend title.

  See: example notebook.

• New in tooltip customization API:

  • The title() option defines a tooltip "title" text which will always appear above the rest of the tooltip content.
  • The 'newline' character (\n) now works as line break in tooltips.
  • Automatic word wrap: occurs when the length of a text value in tooltip exceeds the 30 characters limit.

  See: example notebook.

• Parameter scales in facet_grid()/facet_wrap() [#451,
  #479].

  See: example notebook.

• New in geom_livemap():

  • The Reset button: returns the map widget to its initial zoom/location state.
  • Parameters data_size_zoomin, const_size_zoomin: allow configuring how zooming-in of the map widget increases size of geometry objects (circles, lines etc.) on map.
  • Parameter ontop that controls z-index of the geom_livemap layer.
  • Parameter show_coord_pick_tools to show "copy location" and "draw geometry" buttons.

• New geometries:

  • geom_violin()

  See: example notebook.

  • geom_dotplot()

  See: example notebook.

  • geom_ydotplot()

  See: example notebook.

Changed

• New tooltip style: rounded corners, bold label, colored marker inside the tooltip.
• Deprecated tooltip customization API:
  function color() will be removed in one of the future releases.
• 'Auto shrink': plots automatically shrink when necessary to fit width of the output (notebook) cell [#488].

Fixed

• LiveMap, Swing-batik: legend is not visible when overlapping map [#496].
• CVE-2021-23792 in org.jetbrains.lets-plot:[email protected] [#497].
• Color in tooltip does not correspond to the color of marker on map [#227].
• tooltip on livemap: hide tooltip when the cursor is over the controls [#335].
• Automatic detection of DateTime series [#99].
• Fix tooltips for geom_histogram(stat='density').
• The axis tooltip overlaps the general tooltip [#515].
• The multi-layer tooltip detection strategy will only be used if more than one layer provides tooltips.

Updated version v2.3.0rc1

v2.2.1

[2.2.1] - 2021-12-10

Added

• scale_x_time() and scale_y_time() [#468].

  See: example notebook.

• plot_background, legend_background parameters in theme() [#485].

• axis_ontop, axis_ontop_x, axis_ontop_y parameters in theme()

Fixed

• Coord system limits do not work with x/y scale with transform [#474].
• Provide 0-23 hour formatting [#469].
• No tooltip shown when I'm trying to add an empty line [#382].
• coord_fixed() should adjust dimensions of "geom" panel accordingly [#478].
• The tooltip dependence on number of factors works separately by layers [#481].

v2.2.1rc1

Updated version v2.2.1rc1

v2.2.0

[2.2.0] - 2021-10-29

Added

• coord_flip().

  See: example notebook.

• Date-time formatting support:

  • tooltip format() should understand date-time format pattern [#387];
  • scale_x_datetime should apply date-time formatting to the breaks [#392].

  See: example notebook.

• Pre-configured themes:

  • Standard ggplot2 themes: theme_grey(), theme_light(), theme_classic(), theme_minimal();
  • Other themes: theme_minimal2() - the default theme, theme_none().

• Theme modification: more parameters were added the theme() function.

  See: example notebook.

Note: fonts size, family and face still can not be configured.

• corr_plot() function now also accepts pre-computed correlation coefficients. I.e. the following two expressions are equivalent:

    corr_plot(iris_df).points().labels().build()
    corr_plot(iris_df.corr()).points().labels().build()  # new

Changed

• The size of fonts on plot was slightly increased all across the board.
• The default plot size was increased by 20%, it's now 600x400 px.
• Deprecated API: stat_corr() and "correlation stat" will be removed in one of the future releases.
  Please use the corr_plot() plot builder object instead.

Fixed

• Ordering facets - the "order" value 0 disables facet ordering [#454].
• Tooltips for discrete variables: add the dependence of the tooltip on the number of factors.
  The X-axis tooltip is always shown for discrete data.
• map_join doesn't work when join variables with same names without mappings [#428].
• Zoom without clipping breaks tooltips [#373].
• Unreadable breaks on axis [#430].
• Map rendering is broken when browser uses scaling [#450].
• corr_plot() error for data with zero variation [#329].
• Misleading error message [#271].
