我目前正在嘗試了解為什么 R 中的金字塔圖中的 bin 大小（在 JupyterNotebook 中運行）關閉。
我有一個非常簡單的表，我在其中使用了 3 個變數：gender、age group和count。
見下表：
跑了一個pyramid_chart，但是，酒吧的大小是關閉的，我不知道如何解決它。
我試圖有一個金字塔圖（也稱為 abidirectional chart或 a side to side chart），但我遇到了問題，facet_share這給了我一個錯誤：R[write to console]: Error in axes$y$left[[1]]$children$axis$grobs[[lab_idx]] : attempt to select less than one element in get1index.
我使用的代碼如下所示：
資料表
val_gen_age<-data.frame(gender = c("Female", "Female","Female","Female","Female","Female","Male","Male","Male","Male","Male"), age group = c("18-24", "25-34", "35-44","45-54","55-64","65 ","18-24", "25-34", "35-44","45-54","55-64"),count = c("1270", "2280", "1257","855","180","450","1449","1170","89"))
uj5u.com熱心網友回復：
條形的大小不同，因為組不均勻。組 55-64 僅存在于Female. 如果您添加一行并add_row填寫 for 的對應項age_group 55-64，Male則條形將與預期的一樣：
library(dplyr)
library(ggcharts)
df1 <- df %>%
add_row(gender ="Male", age_group = "55-64", count = 0)
pyramid_chart(
df1,
age_group,
count,
gender,
bar_colors = c("darkgreen", "darkorange"),
sort = "no",
xlab = NULL,
title = NULL
)
資料：
structure(list(gender = c("Female", "Female", "Female", "Female",
"Female", "Male", "Male", "Male", "Male"), age_group = c("18-24",
"25-34", "35-44", "45-54", "55-64", "18-24", "25-34", "35-44",
"45-54"), count = c(1270L, 2280L, 1257L, 855L, 180L, 450L, 1449L,
1170L, 89L)), class = "data.frame", row.names = c(NA, -9L))
