是指在多密度图中添加垂直线。geom_vline是ggplot2包中的一个函数,用于在图形中添加垂直线。 具体步骤如下: 1. 首先,确保已经安装了ggplot2包,并加载该包。 2. 创建一个数据...
p <- p + geom_vline(xintercept = 2, color = "red", linetype = "dashed") 然后,使用annotate()函数添加文本。可以指定文本的位置、内容、字体大小等参数。 代码语言:txt 复制 p <- p + annotate("text", x = 2, y = 0.5, label = "Vertical Line", size = 4) 在上述代码中,x和y参数...
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...
ggplot(df, aes(x, y)) + geom_tile(aes(fill = factor(z)), colour = "grey50", width = 2, height = 2)+ geom_vline(aes(xintercept=6),linetype="dashed",colour="red",size=1)+ geom_hline(aes(yintercept=24),linetype="dashed",colour="red",size=1)+ scale_x_continuous(expand ...
X <- 1:5 Y <- c(2, 6, 4, 7, 12) 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. ...
dat2 %>% ggplot(aes(Sepal.Length, Sepal.Width)) + geom_point() + geom_texthline(yintercept = 3, label = "hline", hjust = 0.8, color = "red4") + geom_textvline(xintercept = 6, label = "vline", hjust = 0.8, color = "blue4", linetype = 2, vjust = 1.3) + geom_text...
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 ...
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:
您也可以执行geom_vline(xintercept = as.numeric(as.Date("2015-01-01")), linetype=4)。
