ggplot(mtcars, aes(x = wt, y = mpg)) + geom_point(shape = 18, color = "steelblue", size = 4)fill可改变填充色，只适用于形状是21-25 ggplot(mtcars, aes(x = wt, y = mpg)) + geom_point(shape = 23, fill = "blue", color = "darkred", size = 3)添加分组元素（默认 gg...
进行绘图将shape列数据映射到aes(shape) library(ggplot2) p=ggplot(dat,aes(x=X,y=Y,shape=shape))+ geom_point(size=20)print(p) AI代码助手复制代码 将直接报错,注意先转化因子: dat$shape=factor(dat$shape) p=ggplot(dat,aes(x=X,y=Y,shape=shape))+ geom_point(size=10)print(p) AI代码助手...

1、简单散点图 使用geom_point()函数即可绘制,并且在映射中可以使用以下映射参数: shape:指定形状 colour:填充(需要注意的是,fill对point可能...
在ggplot中,我们可以通过geom_point()函数来绘制散点图,并通过设置shape参数来指定点的形状。下面是一个简单的例子,展示了如何使用ggplot绘制带有不同点形状的散点图: ```R library(ggplot2) # 创建数据框 data <- data.frame(x = runif(100), y = runif(100), category = sample(c("A", "B", "C...
