Rstudio重新排序堆疊的ggplot geom_bar

Question

所以我在@Axeman的幫助下制作了一個堆積的Barplot。 到目前為止，一切都很好。現在，我想將藍色情節與紅色情節交換。 我確實使用ggplot中的order函數嘗試了所有操作，但我做對了。 這是情節：

堆積條形圖

在下面，您可以找到用於此繪圖的數據框的摘錄（第一行包含標題）。 基本上是部門名稱，后面是兩種類型的儲蓄（重復和MDF），最后一列包含這兩種儲蓄的總和（NewRepetitive + Anrechenbare_MDF）

這是用於以正確方式（使用tidyr包）編輯數據框的R代碼，因此我可以制作堆疊式barplot，因為ggplot需要特定格式的數據。

  library(ggplot2)
  library(tidyr) 

  pd <- gather(stack, 'key', 'value', -DivisionName)
  pd <- pd[pd$key != 'Total_CR', ]

最后是ggplot代碼：

ggplot(pd, aes(DivisionName,  value, fill = key)) +
  geom_bar(stat = "summary", fun.y = "sum") +
  scale_fill_discrete(name="Saving-Typen",labels=c("MDF-Savings","Repetitive Savings")) +
  ylab("Total Savings") +  scale_y_continuous(breaks=c(seq(0,15000000,1000000)), expand = c(0,0))

該條形圖看起來與我想要的樣子完全一樣，除了順序。.我需要具有“重復保存”以上的“ MDF節省”。 我在這里坐了5個小時，無法找到正確的解決方案。.我已經嘗試過使用“ order”選項進行所有操作。

有人能幫我嗎？

Answer 1

嘗試手動選擇所需的顏色：

+ scale_fill_manual(values=c("#999999", "#E69F00"), 
                       name="Legend title",
                       breaks=c("Electrical", "Power grids"),
                       labels=c("Electrical", "Power grids"))

如http://www.cookbook-r.com/Graphs/Legends_(ggplot2)/

未經測試。

Answer 2

問題不在於您的繪圖代碼，而在於數據框pd 。 您將pd$key作為字符向量而不是因子。 將其轉換為具有正確順序的因數， ggplot將為您完成其余工作。

后

pd <- gather(stack, 'key', 'value', -DivisionName)
pd <- pd[pd$key != 'Total_CR', ]

你做：

pd$key <- factor(pd$key,
                 levels = c("NewRepetitive",
                            "Anrechenbare_MDF"))

不要忘記再次更改標簽以匹配正確的值。

ggplot(pd, aes(DivisionName,  abs(value), fill = key)) +
  geom_bar(stat = "summary", fun.y = "sum") +
  scale_fill_discrete(name="Saving-Typen",labels=c("Repetitive Savings","MDF_Savings")) +
  ylab("Total Savings") +  scale_y_continuous(breaks=c(seq(0,15000000,1000000)), expand = c(0,0))

請注意，由於您的示例數據集晦澀難懂，因此我不得不使用abs(value) 。 請看看如何制作出色的R可重現示例？ 以便將來了解如何提出問題。
