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。geom_histogram()：用于绘制直方图，展示数据的分布情况。geom_histogram()函数通过将x轴划分为多个分段并计算每个分段中的观测值数量，可视化单个连续变量的分布情况。geom_freqpoly()：用于绘制频率多边形，展示数

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
This post explains how to build a line chart that represents several groups with ggplot2. It provides several examples with explanation and reproducible code.

element_line(colour = “gray”), plot.title = element_text(hjust = 0.5), plot.subtitle = element_text(hjust = 0.5) ) + ylab(“”) + xlab(“”)Note that I saved everything except the original graph’s first ggplot() line of code to the custom geom.Here’s how simple...
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 ...
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()
ggplot(data, aes(x, y))+# Draw ggplot2 plotgeom_line()+geom_point() As shown in Figure 1, we created a line and point plot (i.e. a graph where the lines connect the points) using the ggplot2 package with the previously shown R syntax. ...
