geom_tile(colour="black")改为geom_point(colour="black",shape=21,size=4)会得到以下图片 ggplot(dat, aes(x=xvals,y=yvals,fill=yvals))+ geom_point(colour="black",shape=21,size=4)+ scale_fill_gradientn(colours=colormap)+ ylim (0, max(yvals)*1.3)+ theme( text=element_text(size=15,...
ggplot(mpg, aes(class, displ)) + geom_violin(aes(fill = class), show.legend = FALSE) + stat_summary(fun = median, geom = "point", shape = 23, size = 2, fill = "white") 添加均值和标准差 ggplot(mpg, aes(class, displ)) + geom_violin(aes(fill = class), show.legend = FALSE...

要改变geom_dotplot()中点的形状,可以使用shape参数。shape参数控制点的外观,可以指定不同的点形状。 下面是一个示例代码,展示如何在R中改变geom_dotplot中的点的形状: 代码语言:txt 复制 # 导入所需的包 library(ggplot2) # 创建一个数据集 data <- data.frame(x = rnorm(100)) ...
shape, color, fill, sizeggplot(df,aes(x=wt,y=mpg))+geom_point(shape=23,fill="blue",color="darkred",size=3)#Scatter plots with multiple groups# Scatter plot with multiple groups shape depends on cylggplot(df,aes(x=wt,y=mpg,group=cyl))+geom_point(aes(shape=cyl))# Change point ...
shape:点形状 size:点的大小 stroke:描边 这些参数用于修改散点图的图形属性。 一,绘制基本的点图 使用mtcars数据集来绘制散点图,并根据cyl字段来设置每个点的颜色: library(ggplo2) ggplot(mtcars, aes(wt, mpg))+geom_point(aes(colour= factor(cyl))) ...
