我正在try 创建一个Sankey图，但也要指定从上到下报告左侧 node 的顺序.要指定顺序，我必须更改列，将其列为factor.然而，当我这样做时，它会改变 colored颜色 的比例，使其更受限制，scale_fill_viridis的 colored颜色 不那么明显.它几乎就像go 掉了最极端的 colored颜色 .有没有人能帮我恢复所有的 colored颜色 ，同时还能保持左侧 node 的秩序.
我的样本数据框如下所示

这是我用来重新排序的代码，这样左边的 node 就会按特定顺序排列
df2$node <- factor(
df2$node,
levels =
c("Receiver + Mobile + Stationary", "Both + Mobile",
"Receiver + Animal-borne", "No Receiver + Animal-borne + Mobile",
"Both + Baited","No Receiver + Mobile", "Both + Animal-borne","Both + Stationary",
"Receiver + Baited", "No Receiver + Stationary", "Receiver + Mobile",
"Receiver + Stationary", "No Receiver + Animal-borne",
"Reproductive Ecology","Other Drivers","Methodological","Resource-Use Management",
"Fisheries Management","Conservation Measures","Behavioural Ecology")
)
这是我用来绘制图表的代码
remotes::install_github("davidsjoberg/ggsankey")
library(ggsankey)
library("tokenizers")
library(dplyr)
library(tidyr)
library(viridisLite)
library(viridis)
library(ggplot2)
width <- .4
p <- ggplot(df2, aes(x = x, next_x = next_x, node = node, next_node = next_node, fill = factor(node), label = node)) +
geom_sankey(flow.alpha = 1, node.color = "black", show.legend = FALSE, width = width) +
theme_void() +
theme(
plot.margin = unit(rep(5.5, 4), "pt")
) +
#I have tried to play around with this code to change scale but to no avail
scale_fill_viridis_d(begin = 1.0, end = 0)
# Get the data from the flows layer
dat <- layer_data(last_plot(), 1) |>
filter(x == 2 - width / 2) |>
distinct(fill, flow_end_ymax, .keep_all = TRUE)
p = p +
geom_rect(data = dat, aes(
xmin = x, xmax = x + width,
ymin = flow_end_ymin, ymax = flow_end_ymax,
fill = label
), inherit.aes = FALSE) +
geom_sankey_label(size = 5, color = "black", fill = "white") +
guides(fill = "none")
p
this is the image I get
But I want the colours to have the full range from the yellow to dark blue like this picture
有什么 idea 吗？
