ggplot2是一个用于创建统计图形的强大 R 语言包,由 Hadley Wickham 开发。它基于“Grammar of Graphics”理论,允许用户通过组合不同的图形元素(如几何对象、比例尺、颜色映射等)来创建复杂的图形。 堆叠条形图(Stacked Bar Chart)是一种条形图,其中每个条形被分割成多个段,每个段代表一个类别的数据,并且这些段堆叠...
ggplot(df_bar, aes(x = category, y = value)) + geom_bar(stat = "identity") + ggtitle("条形图示例") + xlab("类别") + ylab("值")```注意,这里`stat = "identity"`表示直接使用`y`列的值作为条形的高度,而不是计算频数。### 3. 折线图(Line Chart)折线图用于展示连续变量随时间或...

The example code below creates a bar chart from Boston snowfall data, and it has several lines of customizations that I’d like to use again with other data. The first code block is the initial graph:library(ggplot2)library(scales)library(rio)snowfall2000s <- import(“https://gist.github...
