In ggrepel: Automatically Position Non-Overlapping Text Labels with 'ggplot2'

ggrepel 0.9.6

Changes

• Remove exclude_outside() from geom_text_repel() and geom_label_repel() because this change introduced too many breaking changes for other users. See issues:
• https://github.com/slowkow/ggrepel/issues/253
• https://github.com/slowkow/ggrepel/issues/255
• https://github.com/slowkow/ggrepel/issues/257
• https://github.com/slowkow/ggrepel/issues/260
• https://github.com/slowkow/ggrepel/issues/261

ggrepel 0.9.5

Changes

• Introduce a new function exclude_outside() into geom_text_repel() and geom_label_repel() to discard labels outside the panel range, in order to support the ggbreak package. See issue 244 for details.

• Change expect_equal() to include a tolerance, to satisfy CRAN testing.

• Delete note about old (before 2.2.1) versions of ggplot2, thanks to @olivroy for pull request 246.

• Add website link to DESCRIPTION, thanks to @olivroy for pull request 241.

ggrepel 0.9.4

Changes

• Add min.segment.length to the options table in the examples page, thanks to @jwhendy for mentioning this.

• Add example for how to use ggrepel with sf objects, i.e. geom_text_repel(..., stat = "sf_coordinates"), thanks to @francisbarton for pull request 236.

• Use expect_equal(x, y) instead of expect_true(identical(x, y)), see issue 242 for details.

ggrepel 0.9.3

Bug fixes

• When we set the seed in ggrepel::geom_text_repel(seed = 1), this will no longer override the seed for other unrelated code. Thanks to @kassambara for reporting this in issue 228.

ggrepel 0.9.2

Bug fixes

• Fix compiler errors for C++ expressions like v[i] = {0,0} that arise for some versions of the clang compiler. Thanks to @Krascal and @vrognas for reporting this in issue 184.

• Fix warning from CRAN warning: use of bitwise '&' with boolean operands

Changes

• Change internal column names, so that ggrepel::position_nudge_repel() can now be used with ggplot2::geom_text(). This should also allow us to use new nudge functions from the ggpp package by @aphalo. Thanks to @aphalo for pull request 193.

• Improve handling of justification for angle different from zero in ggrepel::geom_text_repel() pull request 196.

ggrepel 0.9.1 2021-01-09

Bug fixes

• Fix label positions (only for geom_label_repel()). The same plot would look OK with ggrepel 0.8.2, but incorrect with ggrepel 0.9.0. Thanks to Ben Baumer (@beanumber) for reporting this in issue 182.

• Fix a bug that caused R to crash (only on Windows, not on Linux or macOS) for some specific code examples. Thanks to Pedro Aphalo (@aphalo) for reporting this in issue 179 and for testing the patched code.

ggrepel 0.9.0 2020-12-14

Changes

• Points can be different sizes. Repel text labels from large points and small points. New examples in the vignette show how to do this. See discussion about this feature in issue 83.

• New parameter max.overlaps stops ggrepel from trying to label overcrowded data points. The default setting is max.overlaps = 10, so text labels that overlap more than 10 things (points or labels) will be excluded from further calculations and rendering. Of course, we can set max.overlaps = Inf to restore the behavior in ggrepel 0.8.1. See [issue 48] for more discussion. We can also use option(ggrepel.max.overlaps = Inf) to disable this new functionality and display all labels, regardless of too many overlaps.

• Add examples to the vignette for ggplot2::position_jitter() and ggbeeswarm::position_quasirandom()

• Line segments can now be curved (#131, @malcolmbarrett). Add examples to the vignette showing different options.

• Add support for new aesthetics:

• segment.size
• segment.colour
• segment.alpha
• segment.curvature
• segment.angle

• segment.ncp

• Add max.time option to limit the number of seconds spent trying to position the text labels.

• Add verbose option to show timing information: seconds elapse, iteration count, number of remaining overlaps (thanks to @MichaelChirico #159).

• Add bg.color and bg.r aesthetics for geom_text() to display shadows behind text labels. Thanks to @rcannood for adding this feature with pull request 142.

Bug fixes and improvements

• Line segments are the same color as the text by default (#164, @lishinkou).

• Text justification for multi-line text labels should be working as expected. Thanks to @johnhenrypezzuto and @phalteman for comments in issue 137.

• Put text labels on top of all line segments (@kiendang). This fixes issue 35, where line segments sometimes appear on top of text.

• Thanks to Paul Murrell (@pmur002) for notifying us to use is.unit(x) instead of class(x) == "unit" in issue 141. This should future-proof ggrepel for new versions of the grid package.

• Fix the way xlim = c(-Inf, Inf) is treated. Thanks to @thomasp85 for pointing out the bug in issue 136.

• Add new segment options. Thanks to @krassowski for adding this feature with pull request 151.

• segment.shape
• segment.square
• segment.squareShape
• segment.inflect

ggrepel 0.8.1 2019-05-07

Bug fixes and improvements

• Fix heap buffer overflow that causes R to crash. See issue 115. Thanks to Brodie Gaslam (@brodieG) for helping me to setup an environment to reproduce the bug on my own system.

ggrepel 0.8.0 2018-05-09

Bug fixes and improvements

• Fix geom_label_repel(..., point.padding=NA). Reported by @mlell in issue 104.

ggrepel 0.7.3 2018-02-09

Changes

• Add support for position parameter. See issue 69. This allows us to add text labels to points positioned with position_jitter(), position_dodge(), position_jitterdodge(), etc.

Please note that this feature will not work with ggplot2 2.2.1 or older.

ggrepel 0.7.2 2018-01-14

Bug fixes and improvements

Thanks to @AliciaSchep and @aphalo

• Fix warning about hjust. See issue 93.

• Fix bug when subset of points is labeled in geom_label_repel. See issue 92.

ggrepel 0.7.1 2017-11-18

Changes

Thanks to @AliciaSchep

• Add support for hjust and vjust parameters. See issue 69. Also see new examples in the vignette.

• Add code to avoid intersecting line segments. See issue 34.

ggrepel 0.7.0 2017-09-28

Bug fixes

• Fix intersection between lines and rectangles, to reproduce the same aesthetically pleasant behavior as in version 0.6.5.

This is an improvement on the sloppy implementation introduced in 0.6.8. See commit 28633d for more information.

ggrepel 0.6.12 2017-07-16

Changes

• Reproduce identical plots by using seed = 1 to set the seed in geom_text_repel() or geom_label_repel(). By default, no seed will be set.

This is an improvement on the sloppy implementation introduced in 0.6.2. See issue 33 and issue 73 for more discussion of this feature. Thanks to Pierre Gramme for reminding me about this via email.

ggrepel 0.6.11 2017-07-08

Changes

Thanks to @seaaan

• Allow certain parameters to be passed as numbers or unit() instead of only units. See issue 79.

ggrepel 0.6.10 2017-03-07

Bug fixes

Thanks to @zkamvar

• Fix the crash for plots that do not specify xlim or ylim. See pull 74.

ggrepel 0.6.9 2017-03-07

Bug fixes

• Fix the crash for plots with facet_wrap or facet_grid that have no labeled points. Thanks to @pcroteau for pull 70.

ggrepel 0.6.8 2017-02-12

Changes

• Constrain repulsion force to x-axis "x" or y-axis "y" with direction in geom_text_repel() and geom_label_repel(). Thanks to @AliciaSchep for pull 68.

ggrepel 0.6.7 2017-01-09

Changes

• Constrain text labels to specific areas of the plot with xlim and ylim in geom_text_repel() and geom_label_repel(). Thanks to @lukauskas for pull 67.

ggrepel 0.6.6 2016-11-28

Bug fixes

• Mathematical expressions as labels with parse = TRUE in geom_text_repel() and geom_label_repel(). Thanks to @fawda123 for issue 60.

ggrepel 0.6.5 2016-11-22

Changes

Thanks to @jiho for these:

• changed alpha in geom_label_repel() to control text, label background, label border, and segment.

• Allow segment.colour as well as segment.color.

• By default, map text color and text alpha to the segment color unless they are overridden.

• Call scales::alpha() instead of alpha().

ggrepel 0.6.4 2016-11-08

Bug fixes

• Fix a bug that caused ggrepel to fail on polar coordinates coord_polar(). See issue 56.

ggrepel 0.6.3 2016-10-14

Changes

• Use point.padding=NA to ignore data points in repulsion calculations.

ggrepel 0.6.2 2016-10-06

Bug fixes

• Stop the labels from escaping the plot boundaries instead of applying a force at the boundary.

• Call set.seed within geom_text_repel() and geom_label_repel() to allow recreating identical plots. Thanks to @erikor for issue 33.

Changes

• Add min.segment.length to geom_text_repel() and geom_label_repel().

ggrepel 0.6.1 2016-10-04

Changes

• Tweak repel_boxes.cpp. Dampen forces to tune how the labels move. The result looks better, at least for the examples in the vignette.

ggrepel 0.6.0 2016-10-03

Changes

• Do not draw labels with empty strings. When a label is an empty string, the text will not be shown, the segment will not be drawn, but the corresponding data point will repel other labels. See issue 51.

• Add segment.alpha as an option for geom_text_repel() and geom_label_repel().

• Implement angle aesthetic for geom_text_repel(), the same way as done in ggplot2 geom_text().

• Move nudge_x and nudge_y out of the aesthetics function aes(). This makes ggrepel consistent with ggplot2 functions geom_text() and geom_label(). Backwards incompatible with 0.5.1.

• Restore segment.color as an option for geom_text_repel() and geom_label_repel().

• Tweak repel_boxes.cpp. Do not weight repulsion force by ratios of bounding box heights and widths. This seems to perform better, especially after rotating text labels.

ggrepel 0.5.1 2016-02-22

• Optimize C++ code further by reducing number of calls to rnorm().

ggrepel 0.5 2016-02-08

• First push to CRAN.

ggrepel 0.4.6 2016-02-07

Changes

• Tweak point.padding so that users can configure how far labels are pushed away from data points.

ggrepel 0.4.5 2016-02-06

Changes

• Optimize C++ code for a 2.5X speed improvment.

• Delete unnecessary .Rd files.

ggrepel 0.4.4 2016-02-05

FIXES

• Fix the bug when the line segment from the data point points to the origin at (0,0) instead of the text label.

Changes

• Automatically recompute repulsion between labels after resizing the plot.

ggrepel 0.4.3 2016-01-18

Changes

• Change distance between segment and label in geom_label_repel(). Now there is no gap between the end of the segment and the label border.

ggrepel 0.4.2 2016-01-15

FIXES

• Fix spring_force() so that it never returns NaN.

Changes

• Add nudge_x and nudge_y to better control positioning of labels.

ggrepel 0.4.1 2016-01-13

Changes

• Add arrow parameter to allow plotting arrows that point to the labeled data points rather than plain line segments.

• Always draw segments, even if the labeled point is very close to the label.

FIXES

• Fix point.padding so that horizontal and vertical padding is calculated correctly.

• Tweak forces to improve layout near borders and in crowded areas.

ggrepel 0.4 2016-01-12

Bug fixes

• Fix issue 7. Labels can now be placed anywhere in the plotting area instead of being limited to the x and y ranges of their corresponding data points.

• Fix DESCRIPTION to require ggplot2 >= 2.0.0

Changes

• Add new parameter point.padding to add padding around the labeled points. The line segment will stop before reaching the coordinates of the point. The text labels are also now padded from the line segment to improve legibility.

• Add volcano plot to the vignette usage examples.

• Add Travis continuous integration to test against R-devel, R-release, and R-oldrel.

• Dampen repulsion force to slightly improve algorithm efficiency.

• Move intersect_line_rectangle() to src/repel_boxes.cpp.

ggrepel 0.3 2016-01-08

Changes

• Remove unused imports: colorspace.

• Update NAMESPACE with new version of roxygen.

• Use spring force to attract each label to its own point.

• Change default maximum iterations from 10,000 to 2000.

• Update man pages.

• Remove unused code.

ggrepel 0.2.0 2016-01-07

Changes

• Update geom_text_repel() and geom_label_repel().

  • Change label.padding to box.padding.

  • Remove unsupported parameters:

    • position
    • nudge_x
    • nudge_y
    • hjust
    • vjust

• Remove unused imports.

Documentation

• Add roxygen docs to all functions.

ggrepel 0.1.0 2016-01-05

Changes

• Add geom_label_repel().

• Add fudge width to help with legends.

• Add expand=TRUE to allow text to be placed in the expanded plot area.

• Add man/ folder.

• Add links to ggplot2 docs in vignette.

• Add unused R implementation of repel_boxes(), just for your reference.

ggrepel 0.0.1 2016-01-04
