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,并且这些段堆叠在一起形成一个完整的条形。 相关优势 灵活性:ggplot2提供了丰富的自定义选项,可以轻松调整图形的外观和布局。 可读性:通过使用ggplot2,可以创建清晰、美观且易于理解的图形。
可以使用geom_bar函数绘制片段图,并使用fill参数指定不同类别的颜色。 代码语言:txt 复制 library(ggplot2) # 准备数据 df <- data.frame( category = c("A", "B", "C"), percentage = c(30, 40, 30) ) # 创建基础图形对象 p <- ggplot(df, aes(x = "", y = percentage, fill = ...
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.githubu...

I have a bar graph coming from one set of monthly data and I want to overlay on it data from another set of monthly data in the form of a line. Here is a simplified example (in my data the second data set is not a simple manipulation of the first): library(reshape2) libr...
The variables A and B will be plotted as stacked bar graph and the C will be plotted as line chart in the same plot. I have generated the plot using excel like below: How can I create the same plot in R? You first need to reshape longer, for example withpivot_longer()fromtidyr,...
Bar Plots The upper left corner of the plot of the first plot above shows a bar plot of workshop created with qplot(). From the grammar of graphics approach, that graph has only one type of geometric object: bars. The ggplot() function itself only needs to specify the data set to use...
