r - ggplotly 从单个方面删除数据

Question

我正在尝试为 Shiny 的应用程序创建一个绘图图。我遇到了某些多面图布局的问题。每当有四个分面并且它们位于 2x2 网格中时，即使数据在 ggplot 中，左下分面也不显示任何数据。数字。当 3x2 网格中有 6 个面时也会发生这种情况，左下角再次被丢弃。 plotly ggplot examples page 上的示例显示几个具有 2x2 网格和正在显示的数据的示例。我不确定问题是什么。任何帮助深表感谢。

代码:

library(ggplot2)
library(dplyr)
library(plotly)

data %>%
  filter(!is.na(result)) %>%
  ggplot(aes(date_time, result)) +
  facet_wrap(~group, scales = "free_y") +
  geom_point() +
  geom_line()


ggplotly()

ggplot输出:


ggplotly输出:

Answer 1

可能这是 ggplotly 中的一个错误。 .
一个解决方案是使用 scales="free"里面 facet_wrap然后手动定义 4 个图的公共(public) x 轴。

p <- data %>%
  filter(!is.na(result)) %>%
  ggplot(aes(date_time, result)) +
  facet_wrap(~group, scales = "free") +
  geom_point() +
  geom_line()

g <- plotly_build(p)
# Set "x3" axis as common x-axis of Plot 1 and 3 
g$x$data[[1]]$xaxis <- "x3"
# Set "x4" axis as common x-axis of Plot 2 and 4
g$x$data[[2]]$xaxis <- "x4"
print(g)

其他解决方案是 here和 here .
