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...

注意:annotate(geom=‘segment’) 等价于 geom_segment(),annotate(geom=‘text’)等价于geom_text(),但是使用annotate会相对更灵活,下面我们来验证一下p + geom_segment( x = 4, y = 35, xend = 2.65, yend = 27, arrow = arrow(length = unit(5, "mm")) ) + geom_text(, x = 4.1, y =...

注释文本(annotate text) 2. 选择适当的字体类型 你可以选择R系统中已安装的字体,或者使用特定的字体文件。如果你使用的是Windows或Mac系统,可以直接调用系统字体。如果你使用的是特定的字体文件(如.ttf或.otf),则需要先将字体文件加载到R环境中。 3. 在ggplot函数中使用相应参数设置字体 你可以使用theme()函数来...
