在GGplot2中使用Geom_Bar [英] Using Geom_Bar in GGplot2

问题描述

因此，我试图在ggplot2中使用geom_bar，我看到人们在网上展示它的所有情况都是某些事物的比较频率.我想要做的图表就是这样的堆积条形图

So I'm trying to use geom_bar in ggplot2, and all of the cases that I see of people demonstrating it online are of comparative frequencies of certain things. The chart that I'm trying to do is the stacked bar graph like this one

但是，我想从值向量中做到这一点.也就是说，假设我有向量

However, I want to do it from a vector of values. That is, let's say I have the vector

v=c(1,2,3,4)

我想得到的不是4个偶数小节，而是一堆4个小节，其中最上面的是1个单位高，而下一个是2个单位(依此类推).在R中可以吗?

Instead of 4 even bars, which is what I understand I would get, I'd like a stack of 4 bars where the top one is 1 unit tall, and the next one down is 2 units tall (etc.). Is this possible in R?

这是我用于图形的代码.它会生成一个普通的条形图，而不是我正在寻找的堆叠版本:

Here is the code that I've used for my graph. It's yielding a normal bar graph, not the stacked version that I'm looking for:

ggplot(data = v, aes(x = factor(x), y = y)) + geom_bar(aes(fill = factor(y)),stat = 'identity')

推荐答案

我认为您可以从这里开始:

I think you can start from this:

v=data.frame(x="My Stacked Bar", y=c(1,2,3,4))

ggplot(data = v, aes(x = factor(x), y = y))+
  geom_bar(aes(fill=factor(y)), stat="identity")
