library(ggplot2) p <- ggplot() # 创建一个空白的图形对象 接下来,使用geom_vline()函数添加垂直线。可以指定垂直线的位置,以及其他参数如颜色、线型等。 代码语言:txt 复制 p <- p + geom_vline(xintercept = 2, color = "red", linetype = "dashed") 然后,使用annotate()函数添加文本。可以指定...

p <- ggplot(data, aes(x = x_variable, y = y_variable)) + geom_point() # 替换x_variable和y_variable为你的变量名 添加垂直线: 代码语言:txt 复制 p <- p + geom_vline(xintercept = c(x1, x2, x3, ...), linetype = c(lt1, lt2, lt3, ...), color = c(color1, color2,...
geom_line(aes(colour = value01), linetype = 2) 2. 参考线 为图形添加参考线对图形的注释非常有用,主要有水平、竖直和对角线三种参考线,对应于三个函数: geom_hline:yintercept(y轴截距) geom_vline:xintercept(x轴截距) geom_abline:slope(斜率) 和intercept(截距) p <- ggplot(mtcars, aes(wt, m...
DF <- data.frame(X, Y) ggplot(data = DF, aes(x = X, y = Y)) + geom_point() + geom_line() + geom_vline(xintercept = 4.5, linetype = 2) 目前的结果: 所需结果示例: -Daniel Valencia C. 1 使用geom_segment(aes(x=X,xend=X,y=0,yend=Y),linetype=2)+ geom_segment(aes(...

如何使geom_label_reject标签居中,使它们位于每个条的中间?需要将vjust = 0.5放入position_fill中:
ggplot(pressure, aes(temperature,pressure))+geom_textline(label="Mercury vapor pressure",size=6,vjust=-0.5,linewidth=1,linecolor="red4",linetype=2,color="deepskyblue4") geom_textdensityandgeom_labeldensity These are the analogues ofgeom_densitythat allows for smoothly curved labels on density ...
