三、修改通过annotate()添加的文本标签的外观:annotate("text",,,) hw_plot + annotate("text",x = 15, y = 53, label = "I'm text", size = 7, family = "Times", fontface = "bold.italic", colour = "red") 四、添加映射数据点值大小的标签的外观: geom_text(aes(label = 要映射的变量...
p+annotate("text",x=4,y=25,label="add text",color="orange",size=5,angle=45,fontface="bold") 2) 生成注释数据集,然后添加 代码语言:javascript 代码运行次数:0 运行 AI代码解释 annotation<-data.frame(x=c(2,4),y=c(20,25),label=c("label 1","label 2")) A:geom_text方式添加 代码语...
annotate()函数的便利性在其他情况下也很有用。例如,注释的一种常见形式是通过在主数据集下方绘制不同颜色的较大点来突出显示点的子集。要突出显示subaru制造的车辆,我们可以使用以下内容创建基本绘图:library(dplyr) p <- ggplot(mpg, aes(displ, hwy)) + # 绘制突出点 geom_point( data = filter(mpg, ...
p <- p + ggtitle("示例标题") + theme( plot.title = element_text(family = "Arial", face = "bold", size = 16, hjust = 0.5) # 设置标题字体 ) print(p) 使用annotate()添加注释文本并设置字体 r p <- p + annotate("text", x = 0, y = 1, label = "注释文本", family...

annotate("text", label ="1509 DOWN", x = -3.5, y = 14, size = 4, colour ="#619CFF", fontface ="bold") 1 2 3 4 5 6 7 8 9 cns_theme <- theme_classic() + # theme_bw() + # theme(panel.grid.major = element_blank(), panel.grid.minor = element_blank(), ...
geom_text(): 文本注释 geom_label(): 文本注释,类似于geom_text(),只是多了个背景框 annotate(): 文本注释 annotation_custom(): 分面时可以在所有的面板进行文本注释 set.seed(1234) df <- mtcars[sample(1:nrow(mtcars), 10), ] df$cyl <- as.factor(df$cyl) 1. 2. 3. 散点图注释 # Scatte...
