我正在嘗試向我的顏色條圖例添加一個垂直居中的標題，但它會將標題堆疊在顏色條的頂部而不是右側。我試過添加 position = "right" 但它沒有幫助，我試過 vjust，hjust 它也不起作用。
它產生的情節：
我想要什么：
代碼：
ggplot(df, aes(x=img_type, y=metric),show.legend = FALSE)
geom_point(aes(size = abs_corr, colour=corr)) scale_size(range =c(-0.1,20) )
scale_colour_gradient2(
low = "#7e1952",
high = "#2f7a9a",
space = "Lab",
na.value = "white",
guide = "colourbar",
aesthetics = "colour",
mid = "white",
limits=c(-1,1), name = "Spearman's Correlation Coefficient"
) guides(size = "none")
theme(legend.key.height = unit(2.5, "cm"))
guides(fill = guide_colourbar(label.position = "right"))
theme(legend.title = element_text(size = 12, angle = 90) )
