basic+labs( colour = "name1", shape = "name2")  image.png
basic + guides(shape=FALSE)  image.png 修改圖例位置要刪除圖例,，請在 #1: no legend basic + theme(legend.position = "none")  #2: around the plot basic + theme(legend.position = "bottom")  #3: inside the plot
basic + theme(
legend.position = c(.95, .95),
legend.justification = c("right", "top"),
legend.box.just = "right",
legend.margin = margin(6, 6, 6, 6)
) 一些自定義圖例的測試# 圖例被紅框包裹 basic + theme(legend.box.background = element_rect(color="red", size=2),legend.box.margin = margin(116, 6, 6, 6))  # 圖例中指示圖標的邊框設置 basic + theme(legend.key = element_rect(fill = "white", colour = "black"))  #圖例中的字體設置 basic + theme(legend.text = element_text(size = 8, colour = "red"))  # 設置圖例中的標題 basic + theme(legend.title = element_text(face = "bold"))  |
