v4.3.1rc1

Updated version v4.3.1rc1

v4.3.0

[4.3.0] - 2024-03-07

Added

• coord_polar()

  The polar coordinate system is most commonly used for pie charts, but
  
  it can also be used for constructing Spyder or Radar charts using the flat option.

  See: example notebook.

• In the theme() function:

  • panel_inset parameter - primarily used for plots with polar coordinates.

    See: example notebook.

  • panel_border_ontop parameter - enables the drawing of panel border on top of the plot geoms.

  • panel_grid_ontop, panel_grid_ontop_x, panel_grid_ontop_y parameters - enable the drawing of grid lines on top of the plot geoms.

• geom_curve()

  See: example notebook.

• [UNIQUE] Visualizing graph-like data with geom_segment() and geom_curve().

  • Aesthetics size_start, size_end, stroke_start and stroke_end enable better alignment of
    
    segments/curves with nodes of the graph by considering the size of the nodes.

  • The spacer parameter allows for additional manual fine-tuning.

  See:

  • A simple graph example
  • An interactive map example

• alpha_stroke parameter in geom_label() to enable the applying of alpha to color [#1029].

  See: example notebook.

• Showing plots in external browser

  The LetsPlot.setup_show_ext() directive allows plots to be displayed in an external browser window.

Changed

• [BREAKING] Function geom_image() is removed. Please use geom_imshow() instead.
• Parameter axis_ontop in theme() is now True by default.

Fixed

• coord_map() should distort tiles size to account for different unit size at different latitudes[#331].
• geom_errorbar(): wrong positioning of tooltips [#992].
• geom_path(): tooltip position interpolation [#855].
• Stacked bar-chart annotation: labels go out of the plot when zooming-in using coord_cartesian(xlim, ylim) [#981].
• Facets: "free scales" options are ignored by discrete axis [#955].
• Bar width is too large when x-domain is defined via x-scale limits [#1013].
• How to hide only main tooltip? [LPK-#232].

• Scale limits don't work for bars/area [LPK-219], [#978].
• No gridlines when axis_ontop=True [#1012].
• bar-plot: do not draw bar border adjacent to the axis [#845].
• Displaying tooltips on a multilayer plot [#1030].
• Make segment geometry better suited for graphs visualization [#572].

Updated version v4.3.0rc2

v4.3.0rc1

Updated version v4.3.0rc1

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: freeze at zoom 10 [#892].
• Enormous CPU / Time/ Memory consumption on some data [#932].

• scale_continuous() fails with non-color aesthetics [#953].
• NumberFormat: g format doesn't use e-notation for small numbers [#965].
• Tooltips: graphical artifacts and bad performance in multi-line plot in Batik [#967].
• Wrong tooltip position on geom_segment() with position adjustment [#963].
