缩小绘图宽度以为ggrepel标签留出更多空间

时间：2019-03-27 19:13:49

标签： r ggplot2 knitr ggrepel

我想缩小打印区域，以便为ggrepel当前被切断的标签留出更多空间。我似乎无法再通过nudge_x()来偏移标签，并且我不想缩小文本大小。

我正在尝试寻找一种压缩图表的方法，以使所有组都更靠近中心，从而在x轴的极限位置留出更多的标签空间。

enter image description here

具体来说，我正在尝试将此图编织为纵向PDF。我尝试在块选项中控制fig.width，但这只是使整个图表变小了。

我想最大化纵向页面上的宽度，但相对于标签区域缩小绘图区域。

如果您愿意更改方法，则可以进行较大的切换，并将用作标签的文本用作轴标签。您可以利用辅助轴为图的每一侧做单独的标签，因此事情看起来很像您现在正在做的事情。

我看到的好处是文本适合，因为它现在是轴的一部分。

首先，这是一个使用rank作为因子的示例。为了获得重复的轴，您必须通过as.numeric()使该因子成为数字值（到目前为止，离散轴没有辅助轴）。然后需要完成一些工作，以获取轴的每一侧的中断和标签，因此我将数据处理移至第二步（并将rank2作为重新排序的因素，以简化{{1} }）。

还要注意在breaks中使用expand来消除面板区域边缘周围的空间。

scale_x_discrete()

从一个简单的r markdown文档中，该示例类似于您的示例（尽管不完全正确）： enter image description here

您可以将ageGenderF_ = ageGenderF_ %>% ungroup() %>% mutate(word = factor(word_, ordered = TRUE, levels = ageGenderFLowRank$word_), rank2 = reorder(rank, -rank) ) ageGenderF_ %>% # https://ibecav.github.io/slopegraph/ ggplot(., aes(x = genAge, y = as.numeric(rank2), group = word_)) + geom_line(aes(color = word_, alpha = 1), size = 1.5) + geom_label(aes(label = rank), size = 2.5, label.padding = unit(0.15, "lines"), label.size = 0.0) + scale_x_discrete(position = "top", expand = c(0, .05) ) + scale_y_continuous(breaks = filter(ageGenderF_, genAge == "Women, 15-19") %>% pull(rank2) %>% as.numeric(), labels = filter(ageGenderF_, genAge == "Women, 15-19") %>% pull(word), sec.axis = dup_axis(~., breaks = filter(ageGenderF_, genAge == "Women, 36+") %>% pull(rank2) %>% as.numeric(), labels = filter(ageGenderF_, genAge == "Women, 36+") %>% pull(word) ) ) + theme_bw() + # Remove the legend theme(legend.position = "none", # Remove the panel border panel.border = element_blank(), # Remove just about everything from the y axis axis.title.y = element_blank(), panel.grid.major.y = element_blank(), panel.grid.minor.y = element_blank(), # Remove a few things from the x axis and increase font size axis.title.x = element_blank(), panel.grid.major.x = element_blank(), axis.text.x.top = element_text(size=10), # Remove x & y tick marks axis.ticks = element_blank(), axis.ticks.length = unit(0, "cm"), # Format title & subtitle plot.title = element_text(size=10, face = "bold", hjust = 0.5), plot.subtitle = element_text(hjust = 0.5) ) 用作数字，使用rank反转y轴。

scale_y_reverse()

一种选择是将图形另存为对象（p，然后使用set_panel_size包中的egg自变量来显式设置面板的高度和宽度（完成此操作在this answer中）。这样的事情会让你接近：

library(egg)
library(grid)

p2 <- set_panel_size(p, width=unit(7,"in"), height=unit(10, "in"))

grid.draw(p2)
