Put median value next to the median bar. Pls help, thanks a lot.

I wann to put median value next to the median bar! But don't how to revise the geom_text function. Pls hep. Thanks in advance.

My code is as follows:

 #2. Data Calculation
ISOFF_normalization=ISOFF$Site_Value
ISOFF_pA<-cbind(ISOFF,ISOFF_normalization)
colnames(ISOFF_pA)[22]="Site_Value_Nor"
  #3 Calculate median value
ISOFF_pA$SPLIT<-as.factor(ISOFF_pA$SPLIT)
median<-ISOFF_pA %>% data.frame(ISOFF_pA$SPLIT,ISOFF_pA$Site_Value_Nor)
median.sum <- aggregate(Site_Value_Nor~SPLIT,median,FUN = "median")
median.sum$Site_Value_Nor<-(format(median.sum$Site_Value_Nor,digits = 3,scientific = TRUE))
median.sum$Site_Value_Nor1<-as.numeric(format(median.sum$Site_Value_Nor,digits = 3,scientific = TRUE))


#Isoff
p<-ggplot(ISOFF_pA,aes(x=as.factor(SPLIT),y=Site_Value_Nor)) + #Chart X and Y, Box color type
  geom_boxplot(position=position_dodge(width=0.8)) + 
  theme_bw() + 
  scale_y_log10(breaks=10^(-1:3)) + coord_cartesian(ylim=c(0.1,1000)) + #scale range set up
  theme(axis.text.y=element_text(family="Times",face="bold",colour="#000000",size=14)) + #y axis items font set up
  theme(axis.text.x=element_text(angle=90,hjust=1,vjust=1)) + #X axis items location spin and calibration
  theme(axis.text.x=element_text(family="Times",face="bold",colour="#000000",size=8.5)) + #x axis items font set up
  xlab("SPLIT") + ylab("ED_xCAnoDT_L40-Isoff (pA)") + #x and y title definition
  theme(axis.title.y=element_text(family="Times",face="bold",colour="#000000",size=14)) + #y title font set up
  theme(axis.title.x=element_text(family="Times",face="bold",colour="#000000",size=14)) + #x title font set up
  theme(axis.line=element_line(colour="#000000")) + #picture frame line definition
  scale_fill_manual(values=c("#AFAAE0","#FFFAF0","#BFFAF0","#AAAAA0","#FFFAF0","#FFFAF0","#FFFAF0","#FFFAF0","#FFFAF0","#FFFAF0","#FFFAF0","#FFFAF0","#FFFAF0","#FFFAF0","#FFFAF0","#FFFAF0","#FFFAF0","#FFFAF0","#FFFAF0","#FFFAF0","#FFFAF0","#FFFAF0","#FFFAF0","#FFFAF0","#FFFAF0","#FFFAF0","#FFFAF0","#FFFAF0","#FFFAF0","#FFFAF0","#FFFAF0","#FFFAF0")) + #box color definition
  guides(fill=FALSE) + geom_point() +  #add point chart
  annotation_logticks() #show log graduation
p+geom_text(data=median.sum, aes(label=(Site_Value_Nor), y = 500 ), 
            size=3,position=position_dodge(width=0.8))

p+geom_text(data=median.sum, aes(label=round(Site_Value_Nor1,2), y = 500 ), 
            size=3,position=position_dodge(width=0.8))

Hi, can you provide a reproducible example. It would make it easier for people to help you.

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…
