本文介绍了在ggplot2中创建堆积密度图的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 29岁程序员,3月因学历无情被辞! 我试图在ggplot2中创建一个堆栈密度图,并且我也试图了解qplot相对于ggplot的工作方式。 我发现下面的例子在线: qplot(depth,..density ..,data = diamonds,geom =density, fill = cut,position =stack) 我尝试将此转换为ggplot的调用,想知道它是如何工作的: ggplot(diamonds,aes(x = depth,y = .. density ..)) + geom_density(aes(fill = cut,position =stack)) 创建一个密度图,但不是堆叠它。 什么是qplot创建和ggplot创建的不同? p> 以下是堆积密度图: 非堆积密度图: 原始示例是 here 解决方案来自@ kohske的评论,不是美学的,所以不应该在 aes 调用中: ggplot(钻石,aes(x = depth,y = .. density ..))+ geom_density(aes(fill = cut),position =stack) 或使用电影数据(您的示例图使用): ggplot(aes(fill = mpaa),position =stack) geg_density c> I'm trying to create a stacked density graph in ggplot2, and I am also trying to understand how qplot works relative to ggplot.I found the following example online:qplot(depth, ..density.., data=diamonds, geom="density", fill=cut, position="stack")I tried translating this into a call to ggplot because I want to understand how it works:ggplot(diamonds, aes(x=depth, y=..density..)) + geom_density(aes(fill=cut, position="stack"))This creates a density graph, but does not stack it.What is the different between what qplot is creating and what ggplot is creating?Here is a stacked density graph:Non-stacked density graph:Original example is here 解决方案 From @kohske's comment, the position is not an aesthetic, and so should not be inside the aes call:ggplot(diamonds, aes(x=depth, y=..density..)) + geom_density(aes(fill=cut), position="stack")or using the movies data (which your example graphs use):ggplot(movies, aes(x=rating, y=..density..)) + geom_density(aes(fill=mpaa), position="stack") 这篇关于在ggplot2中创建堆积密度图的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 上岸,阿里云! 09-03 15:44
