R：如何：使用 gplot 和 geom_密度绘制 3d 密度图

I'm trying to combine multiple density plots with overlay. ggplot and geom_density do the job, but the densities are stacked on top of each other.

ggplot(all.complete, aes(x=humid_temp)) +  
  geom_density(aes(group=height, colour=height, fill=height.f, alpha=0.1)) + 
  guides(fill = guide_legend(override.aes = list(colour = NULL))) +
  labs(main="Temperature by Height", x="Temperature", y="Density")

Something similar to this is what I'm trying to achieve:

就我而言，年份将被身高代替。

谢谢！！！

您正在寻找的图表称为山脊线图。尝试一下ggridges https://cran.r-project.org/web/packages/ggridges/vignettes/introduction.html封装有ggplot2.

时间数据的示例：

library(viridis)
ggplot(lincoln_weather, aes(x = `Mean Temperature [F]`, y = `Month`, fill = ..x..)) +
  geom_density_ridges_gradient(scale = 3, rel_min_height = 0.01, gradient_lwd = 1.) +
  scale_x_continuous(expand = c(0.01, 0)) +
  scale_y_discrete(expand = c(0.01, 0)) +
  scale_fill_viridis(name = "Temp. [F]", option = "C") +
  labs(title = 'Temperatures in Lincoln NE',
       subtitle = 'Mean temperatures (Fahrenheit) by month for 2016\nData: Original CSV from the Weather Underground') +
  theme_ridges(font_size = 13, grid = TRUE) + theme(axis.title.y = element_blank())

结果如下：
