我有一個具體問題（至少我喜歡認爲:)）。我想對齊兩列兩行的三個地塊。對齊應該在中心圖之後（見圖;圖C），其中圖A應該在圖C的x軸之後對齊，並且圖D應該與圖C的y軸對齊。注意，沒有圖B，這應該保持空虛。對齊垂直和水平繪圖R ggplot2

這是cowplot一試：

a$GO <- factor(a$GO, levels = a$GO) #keep the same order as in table

coord_flip()
p2
b$day <- factor(b$day, levels = b$day) #keep the same order as in table
p3 <- ggplot(b, aes(x=day, y=Degradation, color=Compound, group=Compound)) +

legend_p1 <- get_legend(p1)
legend_p3 <- get_legend(p3)
p1 <- p1 + theme(legend.position='none')

cowplot::plot_grid(

我想有情節d非常接近曲線C

您是否使用了A和C的x軸相同的價值觀？看到這個例子，它很好地被alligned：'library（ggplot2）;庫（cowplot）; a < - ggplot（cars，aes（x = speed））+ geom_bar（）; c < - ggplot（cars，aes（x = speed，y = dist））+ geom_point（）; d < - ggplot（cars，aes（x = dist，y = speed））+ geom_point（）; plot_grid（a，NULL，c，d，ncol = 2，nrow = 2，rel_widths = c（10/16，6/16，10/16，6/16），labels = c（'A'，''， 'C'，'D'），align =「hv」）' –
_「希望有人能夠嘗試重現某些東西」，嗯，我認爲這是對你的一個可重複的例子。你是否收到關於對齊的消息或警告？ – Axeman
@ m-dz，無論X軸值如何，繪圖區域將會/應該對齊。傳說可能會提供問題。 – Axeman
