本文介绍了从ggplot2中抑制facet_wrap中的轴比例的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我已经用 ggplot2 包和 facet_wrap 函数创建了一个情节,我会压制一些x轴使其更清晰易读。
例如,如果x轴比例出现在D,F,H和J盒子上,这里就会更清晰。

我怎么能这么做?



预先感谢!

编辑:可复制的代码

  library(ggplot2)
d < - ggplot(diamonds,aes(carat,price,fill = ..density ..))+
xlim(0,2)+ stat_binhex(na.rm = TRUE)+ theme(aspect。比例= 1)
d + facet_wrap(〜color,nrow = 1)


解决方案

如果你愿意在网格/ grob级别工作,这绝对是可行的。



首先,我们为您的分面图赋予一个ggplot对象

  my_plot< -d + facet_wrap(〜color,nrow = 1)

然后,我们加载gtable所以我们可以使用/操作低级对象。

  library(gtable)

##加载所需的包:grid

现在,我们将ggplot对象提取到TableGrob中ish输出,但我认为它有助于显示facet图的底层结构):

  plot_tab<  -  ggplotGrob(my_plot) 
print(plot_tab)

我的否定式预测正则表达式今天早上不工作,所以如果任何人用这个短正则表达式可以编辑它或评论那真棒。基本上,我们正在筛选出您不想要的x轴元素(在本地再次打印它,以查看发生了什么)。

  plot_filtered <-gtable_filter(plot_tab,
(background | panel | strip_t | axis_l | xlab | ylab | title | axis_b- [1357])),
trim = FALSE)

现在我们做实际的绘图:

  grid.newpage()
grid.draw(plot_filtered)


I have created a plot like the one here with ggplot2 package and facet_wrap function, and I would to suppress some of the x-axis to make it more legible. For example, here it would be more legible if the x-axis scales appeared on boxes D, F, H and J.

How could I do that?

Thanks in advance!

EDIT : the reproducible code

library(ggplot2)
d <- ggplot(diamonds, aes(carat, price, fill = ..density..)) +
  xlim(0, 2) + stat_binhex(na.rm = TRUE) + theme(aspect.ratio = 1)
d + facet_wrap(~ color, nrow = 1)

解决方案

If you're willing to work at the grid/grob-level, it's definitely doable.

First, we assign a ggplot object with your faceted plot

my_plot <- d + facet_wrap(~ color, nrow = 1)

Then, we load up gtable so we can use/manipulate the lower-level objects.

library(gtable)

## Loading required package: grid

Now, we extract the ggplot object into a TableGrob (apologies for the long-ish output, but I think it helps show the underlying structure of the facet plots):

plot_tab <- ggplotGrob(my_plot)
print(plot_tab)

## 33 32 ( 2- 2, 4-22)      title               text[plot.title.text.261]

My negating-look-ahead-regex-fu is not working this morning, so if anyone with a shorter regex for this could edit it or comment that'd be awesome. Basically, we're filtering out the x-axis elements you don't want (print it again locally to see what's gone).

plot_filtered <- gtable_filter(plot_tab, 
                     "(background|panel|strip_t|axis_l|xlab|ylab|guide-box|title|axis_b-[1357])",
                     trim=FALSE)

And, now we do the actual plotting:

grid.newpage()
grid.draw(plot_filtered)
