首先，谢谢你的任何意见。我对R比较新，所以任何提示/建议都会非常感激。所以我有以下图表： enter image description here

我想重新安排传奇，所以它看起来像这样，所以它更容易理解： enter image description here

我尝试使用scale_fill_discrete无法使用。这是我的代码：

carb_data<- read.csv("Carb_Insulin_BG.csv", header=TRUE)



library(ggplot2)
library(dplyr)

#get data for patient 1
data1<-subset(carb_data,Subject.ID.. == 1)

#get all the data from Visit 1
carb1<-subset(data1,Visit == 1)

visit1 <- toString(carb1[1,3])

carb1<- mutate(carb1, Start=sprintf("%05s", as.character(Start)), Amount= as.numeric(as.character(Amount)))

q <- ggplot(data=carb1, aes(x=Start, y=Amount, group=Description, color= Description, shape=Type, label=Amount )) + geom_text(data=carb1[carb1$Type=="Insulin (units)", ], size=3, hjust=0, vjust=2, color="black") + geom_bar(data=carb1[carb1$Type=="Carb (grams)", ], stat="identity", width=.1) + geom_point(size=2) + theme(text = element_text(size=10), 
          axis.text.x = element_text(angle=90, vjust=1)) + scale_y_continuous(breaks = round(seq(0, max(carb1$Amount), by = 50),2)) + xlab("Time (HH:MM)") + ylab("Value") + ggtitle(toString(c("Carbohydrate, Insulin ,and Blood Glucose Data \n Site ID 1 \nVisit", visit1)))

q

我的数据：
