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...
p <- ggplot(data=data,aes(mpg,wt))+ geom_point(color='darkblue') p 而在aes内部设置colour时,它会将传入的代表颜色的字符型'darkblue'当成一个变量来看待,由于其为单个字符串,于是便被映射为色轮上的起点也即是红色: 代码语言:javascript 代码运行次数:0 复制Cloud Studio 代码运行 p <- ggplot(data...

ggplot(data=mtcars, aes(x=wt,y=mpg))+geom_point(color="red",size=1,shape=0) 常用的图形参数是: color:对点、线和填充区域的边界进行着色 fill:对填充区域着色 alpha:演示的透明度,从透明(0)到不透明(1) linetype:图案的线条(1=实线、2=虚线、3=点、4=点破折号、5=长破折号、6=双破折号) ...
ggplot(data, aes(x = x_variable, y = y_variable, color = color_variable)) + geom_point() 其中,data是数据集的名称,x_variable和y_variable分别是数据集中用于横轴和纵轴的变量,color_variable是用于指定颜色的变量。 在腾讯云的产品中,可以使用腾讯云数据智能(Tencent Cloud Data Intelligence,简称TCDI)来...
