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].
• Make middle strip in geomCrossbar() optional [LPK-233].
• Can't set None for coord limit [#486].
• 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].
