ggforce 0.5.0.9000

ggforce 0.5.0 (2025-06-18)

• Fixed a bug that would cause reordering of data in some geoms (#314)
• The concaveman package is no longer a dependency for geom_mark_hull() (#308)

• Fix a bug in geom_mark_rect() where the mark would not be shown in all panels (#307)
• Fixed a bug in the geom_mark_*() geoms where having NA values in the filter aesthetic would lead to weird errors. NA is now treated as FALSE (#306)
• shapeGrob() is now exported for use by other packages (#303)

• facet_zoom() now throws a better error when used with coord_flip() (#143)

• Prepare for upcoming changes in ggplot2

ggforce 0.4.2 (2024-02-19)

ggforce 0.4.0 (2022-09-29)

• Moved to vctrs internally
• Updated error messaging to use cli
• geom_diagonal(), geom_diagonal_wide(), geom_parallel_sets(), and geom_sina() are now bidirectional in the style of ggplot2
• geom_mark_*() now works correctly in the presence of NA values in x and y
• The zoom, zoom.x, and zoom.y elements now uses proper registration of theme elements, inheriting from strip.background.
• Fixed bug in geom_sina() when groups contained less than 3 points
• Fixed bug in geom_parallel_sets() that erroneously removed grouping information in some configurations
• Added jitter_y argument to geom_sina() to control whether y jittering is performed on integerish y values.
• facet_zoom() now works with patchwork
• Fix bug in geom_mark_ellipse() that caused wrong orientation of ellipses with groups of two.
• gather_set_data() now supports tidyselect.
• position_jitternormal() gains a seed argument in parallel to ggplot2::position_jitter()
• geom_sina() now works when the group only have a single unique y value
• facet_zoom() now works correctly with transformed scales
• facet_wrap_paginate() now works correctly with dir = 'v'
• facet_matrix() now supports a labeller
• fix a bug in geom_parallel_sets_axes() that prevented coloring of axis fill
• fix a bug in stat_circle() if the x and y aesthetics were inherited from the global mapping
• facet_zoom() now works even when limits are set by the scales

ggforce 0.3.4 (2022-08-18)

• Changed documentation to comply with new units package
• Fixed unintentional re-ordering of shapes (#224)
• Deprecate scale_[x|y]_unit in favor of units::scale_[x|y]_units

ggforce 0.3.2 (2020-06-23)

• Changes to comply with latest ggplot2 release
• Make sure ggforce pass test even if concaveman is not available

ggforce 0.3.1 (2019-08-20)

• Better fix for gganimate compatibility (#157)

ggforce 0.3.0 (2019-08-09)

• Added facet_matrix() in order to facet different data columns into different rows and columns in a grid, in order to make e.g. scatterplot matrices and pairs plot
• Added geom_autopoint() and position_auto() to jitter points based on the type of positional scales in the panel
• Added geom_autohistogram() and geom_autodensity() for facilitating distribution plots along the diagonal in a facet_matrix() plot.
• Added facet_row() and facet_col to have one-dimensional facet_wrap() with possibility of variable sizing.
• Stats should now always keep the old group variable (potentially with something added), making them work with gganimate
• Removed the Visual Guide vignette to reduce compilation time. See the website for an overview of all functionality with compiled examples (https://ggforce.data-imaginist.com)

ggforce 0.2.2 (2019-04-23)

• Fixed a regression in geom_sina() where the computation would fail with a warning due to tolower() being masked (#134, #135).

ggforce 0.2.1 (2019-03-12)

• Fixed a bug in the calculation of open and closed b-splines, where the interval would exceed the defined region and result in an out-of-bounds memory error

ggforce 0.2.0 (2019-03-07)

New features

• linear_trans for composing linear transformation using rotate, stretch, shear, reflect, and translate
• facet_stereo added for creating stereographic projections
• geom_voronoi_[tile|segment], geom_delaunay_[tile|segment|segment2], and stat_delvor_summary has been added for tesselation and triangulation.

• Add geom_regon for drawing regular polygons
• Add geom_diagonal, geom_diagonal_wide and geom_parallel_sets for drawing parallel sets diagrams and other visualizations based on diagonals.
