Lut*_*ett 2 background r fill ggplot2 plotly
我正在尝试填充折线图的背景ggplot以指示白天/夜间时段。这个答案中的方法效果很好,但我想使用交互式地显示它们ggplotly,并且由于这个错误而成为一个问题,其中 ggplotly 不喜欢 -Inf 和 Inf 用作 y 限制geom_rect。有谁知道可以与 ggplotly 一起使用的解决方法吗?
为了便于阅读,我将其他答案中的示例代码粘贴到此处:
library(ggplot2)
dat <- data.frame(x = 1:100, y = cumsum(rnorm(100)))
#Breaks for background rectangles
rects <- data.frame(xstart = seq(0,80,20), xend = seq(20,100,20), col = letters[1:5])
p <- ggplot() +
geom_rect(data = rects, aes(xmin = xstart, xmax = xend, ymin = -Inf, ymax = Inf, fill = col), alpha = 0.4) +
geom_line(data = dat, aes(x,y))
p

As juljo mentioned in his comment, the issue is the rectangles' y-range.
To resolve this issue:
Plot your data first
library(ggplot2)
library(plotly)
dat <- data.frame(x = 1:100, y = cumsum(rnorm(100)))
#Breaks for background rectangles
rects <- data.frame(xstart = seq(0,80,20), xend = seq(20,100,20), col = letters[1:5])
# Only plot the data
p <- ggplot() +
geom_line(data = dat, aes(x,y))

Get the y-range of the plot
ylims = ggplot_build(p)$layout$panel_params[[1]]$y.range

Use the y-range to create the rectangles and add them to the plot
p = p +
geom_rect(data = rects, aes(xmin = xstart, xmax = xend, ymin = ylims[1], ymax = ylims[2], fill = col), alpha = 0.4)
