如何根据管道中的汇总值对 geom_col 列进行排序

Question

我尝试理解其他结果，但无法理解。\n这是我的数据集：

我想制作一个按总和（MW）排序的图表，如下所示：

\n\n

HIST %>%\n  group_by(Fonte, UF)%>%\n  summarise(SUMMW = sum(MW))%>%\n  arrange(desc(SUMMW))%>%\n\n  ggplot(aes(x = UF, y = SUMMW, fill = Fonte))+\n\n  theme(axis.text.x = element_text(angle = 90, hjust = 1)) +\n  geom_col()\n

\n\n

但问题是我得到下面的图表，不是按MW总和排序的。我希望该图的列按列的高度排序：

\n\n

我认为最简单的方法是使用以下命令对SUMMW美学函数中的变量重新排序：aesreorder(UF, desc(SUMMW))

HIST %>%
  group_by(Fonte, UF)%>%
  summarise(SUMMW = sum(MW))%>%
  arrange(desc(SUMMW))%>%

  ggplot(aes(x = reorder(UF, desc(SUMMW)), y = SUMMW, fill = Fonte))+

  theme(axis.text.x = element_text(angle = 90, hjust = 1)) +
  geom_col()
