基本思想是ggplot2将数据的几何对象(圆圈,线条等),主题和比例放在上面。...我们还可以使用geom_smooth()在点上添加平滑的趋势线图层。...我们还可以将points geom图层与line geom图层或任何其他类型的geom图层组合在一起。 线图适用于绘制时间序列,因此下面我们使用点和线图层绘制平均预期寿命。...
Note that I saved everything except the original graph’s first ggplot() line of code to the custom geom.Here’s how simple it is to use that new geom:ggplot(snowfall2000s, aes(x = Winter, y = Total)) + my_geom_col()Sharon MachlisGraph created with a custom ggpackets geom.ggpac...

geom: 图形的几何类型(geometry),这又是ggplot2的作图概念。ggplot2用几何类型表示图形类别,比如point表示散点图、line表示曲线图、bar表示柱形图等。 stat: 统计类型(statistics),这个更加特殊。直接将数据统计和图形结合,这是ggplot2强大和受欢迎的原因之一。
An area chart is an extension of a line graph, where the area under the line is filled in. While a line graph measures change between points, an area chart emphasizes the data volume. 代码语言:javascript 代码运行次数:0 运行 AI代码解释 ...
ggplot(economics, aes(date, unemploy)) + geom_line() 假设我们现在想要展示各个总统在任的时候失业率的情况,我们可以先使用geom_rect()引入背景颜色,然后使用geom_vline()引入分隔符,再使用geom_text()添加标签,presidential数据集如下head(presidential) ...
