Basic line chart with ggplot2 and geom_line() A line chart or line graph displays the evolution of one or several numeric variables. Data points are usually connected by straight line segments. You read an extensive definition here. The input data frame requires at least 2 columns: An ...
在R语言中,`ggplot2` 是一个非常流行的数据可视化包,它基于“Grammar of Graphics”理念设计,允许用户通过层叠的方式构建复杂的图形。`geom_line` 是 `ggplot...
Everything start with a basic stacked area chart. You can see many examples in the stacked area chart section of the R graph gallery, including beginner level tutorials. Basically, the ggplot function is used to start a chart with ggplot2. Then, the year column of the dataset (df) is ...

R Line Graphs - Learn how to create line graphs in R with step-by-step examples and techniques to visualize your data effectively.
ggp1<-ggplot(data)+# Draw ggplot2 barplotgeom_bar(aes(group, sample), stat="identity")ggp1 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!
Now, we can use the geom_line & geom_point functions to draw a ggplot2 graph with lines and points: 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...
