ggplotly 1つのファセットからデータを削除

Question

私は、光沢のあるアプリのためのプロットグラフを作成しようとしています。私は、面取りされたプロットの特定のレイアウトに関する問題にぶつかっています。 4つのファセットがあり、それらが2x2グリッドにあるときはいつでも、データがggplot図の中にあっても、左下のファセットはデータを表示しません。これは、3x2グリッドに6つのファセットがあり、その下端が再度ドロップされた場合にも発生します。 plotly ggplot examples pageの例では、2x2グリッドとデータが表示されたいくつかの例を示しています。私は問題が何であるか分かりません。どんな助けも大歓迎です。

コード：

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()

Answer 1

おそらくこれはggplotlyのバグです。
をfacet_wrapの内側に使用し、次に4つのプロットの共通のx軸を手動で定義することです。

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)
