在R中，如何使抖動(geom_jitter())留在其對應的箱線圖中而不延伸到相鄰的箱線圖中？-有解無憂

我想找到一種方法讓抖動保持在自己的箱線圖中，而不會延伸到相鄰的箱線圖中。

到目前為止，我看了這些答案：

在 R 中，如何使抖動 (geom_jitter()) 留在其對應的箱線圖中而不延伸到相鄰的箱線圖中？

如您所見，抖動服從時間點分布（T0、T1、T2、T3），但在診斷（Diagnose）時，它與其他框重疊。

這是我的資料的示例：

structure(list(Time = c("T0", "T0", "T0", "T0", "T0", "T0", "T0", 
"T0", "T0", "T1", "T1", "T1", "T1", "T1", "T1", "T1", "T1", "T2", 
"T2", "T2", "T2", "T2", "T2", "T2", "T2", "T2", "T3", "T3", "T3", 
"T3", "T3", "T3", "T3", "T3", "T3"), Diagnose = c("PDD", "PDD", 
"PDD", "PD-MCI", "PD-MCI", "PD-MCI", "PD", "PD", "PD", "PD", 
"PD", "PD-MCI", "PD-MCI", "PD-MCI", "PDD", "PDD", "PDD", "PD", 
"PD", "PD", "PD-MCI", "PD-MCI", "PD-MCI", "PDD", "PDD", "PDD", 
"PD", "PD", "PD", "PD-MCI", "PD-MCI", "PD-MCI", "PDD", "PDD", 
"PDD"), Values = c(13.47, 14.25, 15, 20, 19.57, 15, 15, 17.54, 
18, 16.93, 11.42, 18, 15, 19.48, 15, 11, 15, 18.03, 11, 15, 17.85, 
19, 15, 15, 17.85, 20, 15, 19, 14.11, 12, 18.31, 16, 17.36, 20, 
12)), row.names = c(NA, -35L), class = c("tbl_df", "tbl", "data.frame"
))

這是使用 position = position_jitter() 、 position=position_jitterdodge() 、 position_dodge、 position_jitterdodge(dodge.width= ) 等時的輸出…… 在 R 中，如何使抖動 (geom_jitter()) 留在其對應的箱線圖中而不延伸到相鄰的箱線圖中？如您所見，這包含了中央箱線圖中的所有抖動。

謝謝！

幾乎！你要找的是geom_point(position = position_jitterdodge()). 您還可以調整寬度jitter.width

 ggplot(df, mapping= aes(x = Time, y = Values)) 
  geom_boxplot(aes(color = Diagnose), outlier.shape = NA )  
  geom_point(aes(color= Diagnose, shape=Diagnose), alpha = 0.5, 
                 position = position_jitterdodge(jitter.width = 0.1))

指定減淡寬度

geom_jitter(width = 0.05)

或者 geom_point(position = position_jitter(width = 0.05))
