如何使用ggplot绘制3D散点图? [英] How to plot 3D scatter diagram using ggplot?

问题描述

我尝试使用"plotly"功能，但是对于我而言，它根本无法正常工作.在2D情况下，"ggplot"正在工作，但是在增加一个轴时却出现错误.如何解决这个问题?

I tried to use "plotly" function but It is not working in my case at all. "ggplot" is working is in a case of 2D but it is giving an error when adding one more axis. How to solve this issue?

ggplot(data,aes(x=D1,y=D2,z=D3,color=Sample))+geom_point()

如何在其中添加一个轴并获得3D图?谢谢你.

How to add one more axis and get the 3D plot in this? Thank You.

推荐答案

由于您用plotly标记了问题，并说您已尝试将其与plotly一起使用，所以我认为为您提供工作上的帮助会有所帮助plotly中的代码解决方案:

Since you tagged your question with plotly and said that you've tried to use it with plotly, I think it would be helpful to give you a working code solution in plotly:

创建一些要绘制的数据:

Creating some data to plot with:

set.seed(417)
library(plotly)
temp <- rnorm(100, mean=30, sd=5)
pressure <- rnorm(100)
dtime <- 1:100

使用plotly的scatter3d类型绘制3d散点图:

Graphing your 3d scatterplot using plotly's scatter3d type:

plot_ly(x=temp, y=pressure, z=dtime, type="scatter3d", mode="markers", color=temp)

呈现以下内容:

ggplot本身不支持3d图形渲染.

ggplot as others have note, by itself does not support 3d graphics rendering.
