# cowplot 1.2.0 - fix `get_legend()` for redesigned ggplot legend system (#202) - fix test for ggplot object class (#210) - fix label order when laying out plots by column rather than by row (@Doubt-0KB, #203) # cowplot 1.1.3 - fix issues with upcoming ggplot 3.5.0. # cowplot 1.1.2 - fix warning message: deprecated `size` argument in `element_rect()` and `element_line()` (@Yunuuuu, #190) # cowplot 1.1.1 - Make sure tests don't fail if vdiffr is missing. # cowplot 1.1.0 - `plot_grid()` now accepts `byrow` as an argument to place plots by row or by column onto the plot area (@BrianLang, #162). - A new null device was added, `agg_null_device()`. - `draw_image()`, `draw_plot()`, and `draw_grob()` have gained additional alignment parameters `halign` and `valign` which allow internal alignment relative to the box into which content is drawn. - In the functions `insert_xaxis_grob()` and `insert_yaxis_grob()`, clipping is now configurable. - Plot assemblies generated by the patchwork package are now supported in `as_grob()`, `ggdraw()`, and `plot_grid()`. # cowplot 1.0.0 ## Breaking changes In many ways, cowplot now behaves more appropriately and plays nicer with the R environment and other R packages. However, this means that several breaking changes were introduced: - The default ggplot2 theme is no longer changed upon loading. You can add `theme_set(theme_cowplot())` to your code to restore the old behavior. - The package ggplot2 needs to be loaded separately from cowplot, it is not automatically attached. - All themes now use parameters `font_size` and `font_family`. Previously, `theme_nothing()` and `theme_map()` used `base_size` and `base_family`. - The function `cowplot::ggsave()` was renamed to `cowplot::ggsave2()`, so that the ggplot2 version of ggsave() is no longer masked by the cowplot version. Other breaking changes: - The defaults for `save_plot()` were changed somewhat. This may require adjustment if you have code depending on it. ## New features - New functions `rectangle_key_glyph()` and `circle_key_glyph()` make it possible to generate customized legend glyphs. - Improved alignment of plots. Plots can now be aligned in a greedy manner, which improves the appearance of aligned plots with axis labels of very different sizes. - The new functions `stamp()`, `stamp_good()`, `stamp_bad()`, `stamp_ugly()`, `stamp_wrong()` allow labeling of plots as good, bad, ugly, wrong, etc. - Added a function `as_grob()` that can convert base plots, lattice plots, and ggplot2 plots into grobs that can then be drawn using standard grid approaches. - Much improved handling of base R plots, thanks to improvements in grid and gridGraphics. Requires R >= 3.6.0 and gridGraphics >= 0.4. - Added a function `set_null_device()` to customize the null graphics device that is used in `ggdraw()`, `plot_grid()`, etc. There is no one null device that always works, so customization is needed. - Added several new themes, including `theme_minimal_grid()`, `theme_minimal_hgrid()`, and `theme_minimal_vgrid()`. Also, `theme_cowplot()` is now also available as `theme_half_open()`. - Expanded functions for extracting plot components from ggplots via `get_plot_component()` and several wrapper functions for getting titles, axes, panels, and so on. This also lets `get_panel()` extract from plots with more than one panel. `get_panel_component()` allows you to further extract components like geoms from the plot panel (@malcolmbarrett, #111). ## Minor changes - Minor tweaks to various legend layout parameters so that legends look better as the underlying theme font size is changed. - Various minor fixes to `theme_cowplot()` and derived themes. - Change `background_grid()` defaults so they match the new grid themes. - Renamed `plot_to_gtable()` to `as_gtable()`. - All functions now understand both spellings of color/colour. - `get_legend()` now returns NULL if there is no legend, instead of raising an error. # cowplot 0.9.4 - Fix CRAN check errors # cowplot 0.9.3 - Fix regression tests to work with ggplot2 3.0.0 # cowplot 0.9.2 - Rewritten cowplot::ggsave function that calls ggplot2::ggsave - More robust handling of R graphics device weirdness/plots popping up in the wrong places # cowplot 0.9.1 - Make examples and vignettes fail gracefully when magick package is not installed # cowplot 0.9.0 - Added a theme for maps, `theme_map()`. Code provided by Spencer Fox, https://github.com/sjfox. - Added `axis_canvas()` function and related functions to make marginal plots and plot annotations simpler - Now export the `plot_to_gtable` function which converts most anything into a gtable for further use with cowplot - Added `inherit.aes = FALSE` to draw functions where needed - Added examples to various draw functions - Added draw_image() function to draw images onto plots # cowplot 0.8.0 - The function plot_grid can now also handle base-R (graphics) plots. Code provided by https://github.com/flying-sheep. - More sophisticated plot alignments of complex plots are now possible. Code provided by Spencer Fox, https://github.com/sjfox. - Plot labels can now be styled. In particular, they follow the theme settings, e.g. if the theme uses a different font than default. This closes issue #37. - The positioning of plot labels in `plot_grid` can now be controlled with additional position parameters `label_x` and `label_y`. This closes issue #32. - Problems with elements from globally set themes leaking into the plot-grid background have been fixed. This closes issues #60, #63, #66. # cowplot 0.7.0 - This version of cowplot has been prepared for the upcoming release of ggplot2 2.2.0. As a result of this upcoming switch, the function switch_axis_position() has been removed. Alternative axes will be natively supported by ggplot2 2.2.0. - As of this version, cowplot requires R >= 3.3.0. This dependency was added because R 3.3 fixes a critical problem with lists of units. # cowplot 0.6.3 - Adds a get_legend() function that extracts the legend from a plot. Code provided by https://github.com/marcus1487 - Fixes bug that creates an empty page on some plot devices. Fix provided by https://github.com/marcus1487 - Fixes bug that hardcoded panel border line-type and size. Fix provided by Spencer Fox, https://github.com/sjfox - Adds the option of custom axes on the drawing layer. Code provided by https://github.com/zaczap - Separates out the alignment function from plot_grid(). Will likely be more useful further down the line. Code provided by Spencer Fox, https://github.com/sjfox # cowplot 0.6.2 - Updated plot_grid vignette so the tutorial on aligning plots of different types works again. This stopped working at some point and was removed from 0.6.1. # cowplot 0.6.1 - Added new convenience function draw_figure_label() to label figures with labels such as "Figure 1". - Fixes in switch_axis_position() so that rotated axis labels work. - Fix missing axis lines in ggplot2 2.1 # cowplot 0.6.0 Major changes: - Now requires ggplot2 version 2.0.0 or higher. Use cowplot 0.5.0 with older versions of ggplot2. - Because of the dependency on ggplot2 2.0.0, the default design is changed. No more bold face for axis labels - Add auto-generation of labels in plot_grid() - Add vignettes describing plot annotations and shared legends among plots # cowplot 0.5.0 Major changes: - Fix label positioning in plot_grid() so it is not affected by the scale parameter - Add draw_label() function which can draw both text and plotmath expressions - Add parameters hjust and vjust to plot_grid() to allow fine-tuning of label position - Add annotations underneath plot, via add_sub() function Other changes: - Improve vignettes # cowplot 0.4.0 Major changes: - Added a function switch_axis_position() which can move/copy the x and/or y axis of a plot to the other side - plot_grid() can now align graphs - plot_grid() can now make grids with varying column widths and row heights Other changes: - Various improvements in the documentation - Code has been separated into multiple files for easier maintenance # cowplot 0.3.1 Fix Vignette title # cowplot 0.3.0 First complete implementation ready for initial release
