ggforce (development version)

  • Changed documentation to comply with new units package

ggforce 0.3.2

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

ggforce 0.3.1

  • Better fix for gganimate compatibility (#157)

ggforce 0.3.0

  • 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 (

ggforce 0.2.2

  • 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

  • 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

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.
  • geom_spiro has been added for drawing spirographs
  • Add geom_ellipse for drawing regular and superellipses
  • 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.
  • Add geom_shape for drawing polygons with rounded corners and expanded/contracted sides. geom_shape replaces all geom_polygon internally.
  • Added geom_bspline_closed to draw polygons defined as b-splines
  • Add geom_mark_[rect|circle|ellipse|hull] to encircle a group of points and optionally add textual annotation to it
  • Add position_jitternormal to jitter points based on a normal distribution (@andrewheiss)


  • facet_[wrap|grid]_paginate will now try to make panels on the last page the same size as on full pages (#7)
  • facet_zoom now gains xlim and ylim arguments to control zoom range directly
  • facet_zoom now gains to control which data gets plotted in which panel
  • Slimmed down the dependencies for the package. plyr, lazyeval and dplyr has all been removed
  • Rewrite geom_sina to match geom_violin and allow for dodging
  • Add open/clamped option to `geom_bspline

Bug fixes

  • Fix interpolation of x and y values in geom_link2 (@thomasp85 and @lepennec)
  • stat_link no longer replicates the group column
  • arcs and links no longer rename aesthetics when only one aesthetic is present (drop = FALSE)
  • stat_bezier0 and stat_bezier2 now return data in the expected format
  • Fix bug with n_pages due to internal changes in ggplot2
  • Fix bug in facet_zoom in combination with secondary y-axis where the space for the y-axis would become huge
  • Correctly detect and error out when scales and coords does not work with facet_zoom
  • The *2 versions of line geoms no longer adds an NA to guides.

ggforce 0.1.1

New features

  • Zoom indicator styling can now be specified separetely for x and y zoom using zoom.x and zoom.y in theme (inherits from zoom that inherits from strip.background)

Bug fixes

  • Fix bug in facet_wrap_paginate that threw errors when using it with free scales (#19)
  • Fixes bug in facet_zoom where y-axis would be incorrectly displayed when zooming on both axes without splitting the view (#23)
  • Fixes bug in facet_zoom where scale expansion where not taken into account when drawing the indicator area (#22)
  • Fixes a bug in facet_zoom that would throw errors with layers not containing the column that is zoomed by (#21)

ggforce 0.1.0

Major changes

  • geom_edge_bundle has been renamed geom_bspline and lost the tension argument. True edge bundle functionality has been moved to ggraph

New features

  • geom_bezier for drawing quadratic and cubic beziers
  • geom_link for augmented segment/path drawing
  • geom_sina as an alternative to geom_violin and geom_beeswarm
  • scale_[x|y]_unit for using units vectors
  • facet_[wrap|grid]_paginate to split facetting into multiple pages
  • facet_zoom for contextual zooming

ggforce 0.0.1

Major changes

  • First commit

New features

  • geom_arc / stat_arc for drawing circle segments
  • geom_edge_bundle / stat_edge_bundle for drawing edge bundles based on control points
  • geom_arc_bar /stat_arc_bar / stat_pie for drawing arcs and wedges with fill
  • geom_circle / stat_circle for drawing circles with radius based on coordinate system scale
  • power_trans for creating power transformations
  • radial_trans for creating transformation between radial and cartesian coordinates
  • trans_reverser for reversing a trans object
