R中的3D表面图 [英] 3D surface plot in R

问题描述

我正在尝试在R-Project中创建3D图.我知道以前有一个类似的问题，但是我无法用那里的答案解决我的问题.

I'm trying to create a 3D plot in R-Project. I know there was a question like this before but I couldn't solve my problems with the answers there.

我所拥有的是:

Vdot_L = c(0,1,2,3,4,5,6,7,8,9,10)
Qdot_verd = c(2000,2100,2200,2300,2400,2500,2600,2700,2800,2900,3000) 
zeta_ex = 0.4
T_U = 293.15 #K
T_verd = 273.15 #K
T_cond=Vdot_L*2+T_U
epsilon_k = zeta_ex * T_verd/(T_cond - T_verd)
Pfun <- function(a,b) {a/b}
P    <- outer(Qdot_verd, epsilon_k, FUN="Pfun")

我要创建的是一个彩色表面图，其中x轴上为Vdot_L，y轴上为Qdot_verd，z轴上为P.我非常感谢您的帮助.

What I'd like to create is a colored surface plot with Vdot_L on the x-Axis, Qdot_verd on the y-Axis and P on the z-Axis. I'm thanful for every help.

推荐答案

是这样的吗?

library(rgl)
zlim        <- range(P,na.rm=T)
zlen        <- zlim[2] - zlim[1] + 1
color.range <- rev(rainbow(zlen))       # height color lookup table
colors      <- color.range[P-zlim[1]+1] # assign colors to heights for each point
persp3d(Vdot_L, Qdot_verd, P, col=colors)
