ggplot(data = economics, aes(x = date, y = psavert))+ geom_line() Plot with multiple lines Well plot both ‘psavert’ and ‘uempmed’ on the same line chart. Solution 1: Make two calls to geom_line(): ggplot(economics, aes(x=date)) + geom_line(aes(y = psavert), color ...
plot <- ggplot(data, aes(x = time)) 使用geom_line函数添加多条线到绘图对象中。可以使用color参数指定每条线的颜色,也可以使用group参数指定每条线的分组: 代码语言:txt 复制 plot <- plot + geom_line(aes(y = var1, color = "Variable 1")) plot <- plot + geom_line(aes(y = var2, color...
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. ...
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 ...
条形图使用 geom_bar (),折线图使用 geom_line (),箱线图使用 geom_boxplot (),散点图使用 geom_point ()。函数 geom_point () 向图中添加一个点层,从而创建散点图。 ggplot( data = penguins, mapping = aes(x = flipper_length_mm, y = body_mass_g) ) + geom_point() #> Warning: ...
