Question

data = cbind(c("A","B","C","A"), c("John", "Kendra", "Martin", "Steve"), c("12","12","13","14"))
colnames(data) = c("Group", "Name", "Score")
data = as.data.frame(data)
p = ggplot(data, aes(x=Name, y=Score, fill=Name)) + geom_point(pch = 19, aes(col=Group)) + scale_colour_manual(values=c("black", "red", "green"))
print(p)

嘿，这段代码产生两个图例：名称和组。如何摆脱名字的传奇？我的意思是整个传奇，而不仅仅是它的标题。编辑：我刚刚弄明白了。你这样说：

p = p + guides(fill=FALSE)

Answer 1

我会稍微调整你的例子以适合我的东西

您可以使用theme修改整个图例，但如果您想将修改限制为单个元素，请改用guide：

data <- cbind(c("A","B","C","A"), c("John", "Kendra", "Martin", "Steve"), c("12","12","13","14"))
colnames(data) <- c("Group", "Name", "Score")
data <- as.data.frame(data)

p <- ggplot(data, aes(x = Name, y = Score, fill = Name)) + 
  geom_point(pch = 19, aes(col = Group)) + 
  scale_colour_manual(values = c("black", "red", "green")) +
  guides(fill = FALSE); p
