如果你想为特定的数据点着色并插入文本标签,你可以使用aes函数来映射颜色属性,并使用geom_text或geom_label来添加文本。 基础概念 aes: aesthetics的缩写,用于映射数据到图形属性。 geom_point: 绘制散点图的几何对象。 geom_text/geom_label: 在图形上添加文本标签的几何对象。 相关优势 可视化数据分布和关...
2、画散点图,通过geom_label显示标签信息 data.plot%>%ggplot(aes(x,y))+geom_point(aes(colour=Class),size=0.5)+scale_colour_brewer(palette="Dark2")+theme_bw()+ggtitle("Class.cluster.plot")+theme(plot.title=element_text(face=2,size=50,hjust=0.5))+geom_label(data=label.data,aes(label=...
+ geom_text(aes(label = c("A", "B", "C")), hjust = -0.2, color = "red") 8. 图例位置 您可以使用position参数调整图例的位置。以下是一些示例代码: 代码语言:txt 复制 + geom_text(position = "identity") + geom_text(position = "bottom") + geom_text(position = "left") 9. 垂直标...
