在ggplot2中绘制"水面"

Question

我正在绘制一些温度数据作为深度的函数.但我希望它对非科学家更友好,并明确表示顶部是水面.有关如何做到这一点的任何想法？(艺术浪潮的奖金!)

目前为止有以下几种选择:

library(dplyr); library(ggplot2); library(magrittr);
temperature <- rnorm(30, mean = 20)
depth <- seq(0:29)
df <- data.frame(temperature, depth)

no_surface <- df %>% 
              ggplot(aes(y = depth, x = temperature, colour = temperature)) +
              geom_path(size = 2) + 
              scale_y_reverse() + 
              scale_colour_gradient(low = "blue", high = "red")+
              theme_classic() + 
              theme(legend.position = "none")


flat_surface <- no_surface + geom_hline(yintercept = 0)

wavy_surface <- no_surface + stat_function(fun = function(x)sin(x^1.5), 
                                           size = 1)

Answer 1

这个很漂亮,我眼里含着泪水:

ggplot(df, aes(xmin=1, xmax=10, ymin=-depth+1, ymax=-depth, fill=temperature)) + 
  annotate("text", x=7, y=1.5, label="\u2600", size = 60, color = "orange") + 
  geom_rect() + 
  geom_area(
    aes(x), data.frame(x=c(1,10)), inherit.aes=F, stat="function",
    fun = function(x)abs(sin(2*x))+.2, fill="blue"
  ) + coord_cartesian(ylim=c(-30, 10)) + 
  theme_minimal() + theme(axis.text.x=element_blank(), axis.ticks.x=element_blank()) + 
  labs(x=NULL, y="level")
