如何填充/遮蔽時間線之間的空間，用ggplot繪製？

Question

我有一個12x13矩陣，看起來像：

monat beob werex_00 werex_11 werex_22 werex_33 werex_44 werex_55 werex_66 werex_77 werex_88 werex_99 Min Max

這是有一定價值的時間線。在下一步我用ggplot()繪製它。所以我用melt()操作以獲取矩陣形狀的情節：

R1_Grundwasserneubildung_Rg1Rg2_Monat_mean_druckreif <- melt(R1_Grundwasserneubildung_Rg1Rg2_Monat_mean, na.rm = FALSE, id.vars="monat") 

這個數據看起來像現在：

Monat Projektion value 
1 1 beob 22.4930171 
2 2 beob 25.1414834 
3 3 beob 33.8286673 
4 4 beob 22.0579421 
5 5 beob 2.5535161 
6 6 beob -2.4405826 
7 7 beob -2.2580848 
8 8 beob -0.3448858 
9 9 beob 3.3963303 
10 10 beob 5.1839209 
11 11 beob 9.2551418 
12 12 beob 18.2233848 
13 1 werex_00 9.1418697 
14 2 werex_00 13.5886794 
15 3 werex_00 16.3800292 
16 4 werex_00 11.9930633 
17 5 werex_00 -2.4503375 
18 6 werex_00 -8.8534136 
19 7 werex_00 -6.7569968 
20 8 werex_00 -5.6683742 
21 9 werex_00 0.4305926 
22 10 werex_00 1.6050281 
23 11 werex_00 4.4810518 
24 12 werex_00 7.7648233 
25 1 werex_11 8.1558828 
... ... ... ... 

我還添加了對熔數據的一些新的名稱（如已經看到以上）：

names(R1_Grundwasserneubildung_Rg1Rg2_Monat_mean_druckreif)<-c("Monat","Projektion","value") 

下一步定義了一些自定義顏色的情節：

Projektionen_Farben<-c("#000000","#00EEEE","#EEAD0E","#006400","#BDB76B","#EE7600","#68228B","#8B0000","#1E90FF","#EE6363","#556B2F","#D6D6D6","#D6D6D6") 

現在我繪製融化數據：

ggplot(R1_Grundwasserneubildung_Rg1Rg2_Monat_mean_druckreif, 
     aes(x=Monat,y=value,color=Projektion,group=Projektion)) + 
     geom_line(size=0.8) + 
     xlab("Monat") + 
     ylab("Grundwasserneubildung [mm/Monat]") + 
     ggtitle("Grundwasserneubildung") + 
     theme_bw() + 
     scale_x_continuous(breaks = c(1,2,3,4,5,6,7,8,9,10,11,12), 
          labels = c("Jan","Feb","Mär","Apr","Mai","Jun","Jul","Aug","Sep","Okt","Nov","Dez")) + 
     theme(axis.title=element_text(size=15,vjust = 0.3, face="bold"), 
      title=element_text(size=15,vjust = 1.5,face="bold")) + 
     scale_colour_manual(values = Projektionen_Farben) 

很抱歉，但我沒有足夠的聲譽張貼情節的照片。 現在我想填充/遮蔽最大線和最小線之間的空間，可以說是淺灰色（alpha = .3）。我嘗試過geom_ribbon()，但還沒有找到正確的方法來根據需要定義x，ymin和ymax。有人知道填補這兩條線之間空隙的方法嗎？

Answer 1

使用您的原始數據框作爲geom_ribbon()，並提供Min和Max列爲ymin和ymax。

+ geom_ribbon(data=R1_Grundwasserneubildung_Rg1Rg2_Monat_mean, 
        aes(x=monat,ymin=Min,ymax=Max), 
        inherit.aes=FALSE,alpha=0.3,color="grey30")
