geom_vline()：用于添加水平、垂直或对角线（由坡度和截距指定），对于注释绘图很有用。
axis.line = element_line(color = "black", linewidth = 0.4), axis.ticks.length = unit(-0.25 , "lines"), axis.minor.ticks.length = unit(-0.15 , "lines")# 设置刻度线朝内,下同,当然如果设置为
它还可以将图表保存到指定的位置。...去掉图例: multiple_line + guides(colour=FALSE) #or multiple_line + theme(legend.position = "none") 改变图例位置 4.2K20 网络可视化R包-geomnet geomnet是一个基于ggplot2可视化图形和网络的R包,它使用sna包计算网络布局,并且包含了使用ggplot2绘制圆的geom_circle函数...

This post explains how to build a line chart that represents several groups with ggplot2. It provides several examples with explanation and reproducible code.
Basic line plots Line plot with multiple groups Change globally the appearance of lines Change automatically the line types by groups Change manually the appearance of lines Functions:geom_line(),geom_step(),geom_path(),geom_errorbar()
By executing the previous code we have plotted Figure 1, i.e. a ggplot2 bargraph without any lines or secondary y-axes. Let’s modify this plot! Example 1: Add Line to ggplot2 Barplot Example 1 illustrates how to overlay a line on top of a ggplot2 barchart. To achieve this, we ...
time: x-axis sex: line color total_bill: y-axis.To draw multiple lines, the points must be grouped by a variable; otherwise all points will be connected by a single line. In this case, we want them to be grouped by sex.# Basic line graph with points ggplot(data=dat1, aes(x=...
