用分面ggplot 2.0.0& amp;& gridExtra [英] Arrange common plot width with facetted ggplot 2.0.0 & gridExtra

问题描述

由于我已更新到ggplot2 2.0.0，因此无法使用gridExtra正确安排图表。问题在于分面图表会被压缩，而其他图表会被展开。宽度基本上是混乱的。我想把它们安排成类似于这些单面图的方式：

正如你所看到的，最上面的图表，第一个面被扩展，而另外两个被压缩在右边。底图不包括所有宽度。

难道新的ggplot2版本与gtable宽度有关吗？

解决方案

其中一个选项是将每个绘图按摩到一个3x3 gtable，其中中央单元格包裹所有绘图面板。

使用@SandyMuspratt中的示例

 ＃devtools :: install_github （baptiste / egg）
 grid.draw（egg :: ggarrange（plots = plots，ncol = 1））
  

Since I have updated to ggplot2 2.0.0, I cannot arrange charts propperly using gridExtra. The issue is that the faceted charts will get compressed while other will expand. The widths are basically messed up. I want to arrange them similar to the way these single facet plots are: left align two graph edges (ggplot)

I put a reproducible code

library(grid) # for unit.pmax()
library(gridExtra)

plot.iris <- ggplot(iris, aes(Sepal.Length, Sepal.Width)) + 
  geom_point() + 
  facet_grid(. ~ Species) + 
  stat_smooth(method = "lm")

plot.mpg <- ggplot(mpg, aes(x = cty, y = hwy, colour = factor(cyl))) + 
  geom_point(size=2.5)

g.iris <- ggplotGrob(plot.iris) # convert to gtable
g.mpg <- ggplotGrob(plot.mpg) # convert to gtable

iris.widths <- g.iris$widths # extract the first three widths, 
mpg.widths <- g.mpg$widths # same for mpg plot
max.widths <- unit.pmax(iris.widths, mpg.widths)

g.iris$widths <- max.widths # assign max. widths to iris gtable
g.mpg$widths <- max.widths # assign max widths to mpg gtable

grid.arrange(g.iris,g.mpg,ncol=1)

As you will see, the top chart, the first facet is expanded while the other 2 get compressed at the right. Bottom chart does not cover all width.

Could it be that the new ggplot2 version is messing with the gtable widths?

Anyone know a workaround?

Thank you very much

I'm looking for something like:

解决方案

one option is to massage each plot into a 3x3 gtable, where the central cell wraps all the plot panels.

Using the example from @SandyMuspratt

# devtools::install_github("baptiste/egg") 
grid.draw(egg::ggarrange(plots=plots, ncol=1))

the advantage being that once in this standardised format, plots may be combined in various layouts much more easily, regardless of number of panels, legends, axes, strips, etc.

grid.newpage()
grid.draw(ggarrange(plots=list(p1,  p4, p2, p3), widths = c(2,1), debug=TRUE))
