[英]Simple one about Alluvial plot in R
I would like to make a simple flow graph.我想制作一个简单的流程图。 Here is my code:这是我的代码:
## Data
x = tibble(qms = c("FLOW", "FLOW"),
move1 = c("Birth", "Birth"),
move2 = c("Direct", NA),
freq = c(100, 50))
## Graph
x %>%
mutate(id = qms) %>%
to_lodes_form(axis = 2:3, id = id) %>%
na.omit() %>%
ggplot(aes(x = x, stratum = stratum, alluvium = id,
y = freq, label = stratum)) +
scale_x_discrete(expand = c(.1, .1)) +
geom_flow(aes(fill = qms),stat = "alluvium") +
geom_stratum(aes(fill = stratum), show.legend=FALSE) +
geom_text(stat = "stratum", size = 3)
This is the outcome:这是结果:
My desired outcome is that:我想要的结果是:
How can I express the decreasing pattern with the missing value?如何用缺失值表示递减模式?
By slightly reshaping your data you can get what you want.通过稍微重塑您的数据,您可以获得您想要的。 I think the key is to map the alluvium
to something fixed like 1
so that it will be a single flow, and mapping stratum
to the same variable as x
.我认为关键是 map 将alluvium
固定为1
之类的东西,这样它将成为一个单一的流,并将stratum
映射到与x
相同的变量。
library(tidyverse)
library(ggalluvial)
x <- tibble(x = c("Birth", "Direct"),
y = c(100, 50))
x %>%
ggplot(aes(x, y, alluvium = 1, stratum = x)) +
geom_alluvium() +
geom_stratum()
