如何在ggplot2中为treemap的标签文本设置相同的大小

Question

我使用以下代码绘制了树状图：

library(treemap)
library(ggplot2)
ggplot2::ggplot(G20, ggplot2::aes(area = gdp_mil_usd, fill = econ_classification,label = country), size = 4) +
  geom_treemap() +
  geom_treemap_text(grow = T, reflow = T, colour = "black", place = "centre", family = "STKaiti", size = 4)

输出：

现在我想知道是否可以设置相同大小的标签文本，我在ggplot()和geom_treemap_text()中添加了参数size = 4，但是没有用。

有人可以帮忙解决这个问题吗？谢谢。

Answer 1

在geom_treemap_text中设置grow=FALSE。

library(treemapify)
library(ggplot2)
ggplot2::ggplot(G20, ggplot2::aes(area = gdp_mil_usd, 
               fill = econ_classification, label = country)) +
  geom_treemap() +
  geom_treemap_text(grow = F, reflow = T, colour = "black", 
                    place = "centre", family = "STKaiti", size = 14)
