更改表面着色(使用grid :: wireframe) [英] Changing the surface coloring (using lattice::wireframe)

问题描述

我正在使用grid :: wireframe创建一个曲面.我需要更改颜色，使其取决于x或y变量(而不是z).应该怎么做?该文档说，颜色是根据高度(例如z)自动选择的.

I am using lattice::wireframe to create a surface. I need to change the coloring so that it depends on the x or y variable (instead of on z). How should this be done? The documentation says that the color is automatically chosen to depend on the height (e.g. z).

谢谢！ 乔治(Georgi)

推荐答案

使用col.regions

wireframe(volcano, drape = TRUE,
       aspect = c(61/87, 0.4),
       light.source = c(10,0,10), 
       col.regions = colorRampPalette(c("blue", "pink"))(100))

根据您的评论以及@DWin的启发，我相信在这里，他们会做得更好，也许通过?persp您可以更接近您想要的东西.

As per your coment and with inspiration from @DWin who I am sure will do a better job here, perhaps with ?persp you can get closer to what you want.

> persp(x, y, z, theta = 135, phi = 30, col = colorRampPalette(c("blue", "pink"))(9500), scale = FALSE,
+       ltheta = -120, shade = 0.75, border = NA, box = FALSE)
