Plotly R 顺序图例条目
Plotly R order legend entries
是否可以在 R 中对图例条目进行排序?
如果我指定这样的饼图:
plot_ly(df, labels = Product, values = Patients, type = "pie",
marker = list(colors = Color), textfont=list(color = "white")) %>%
layout(legend = list(x = 1, y = 0.5))
图例按患者人数最多的产品排序。我希望图例按产品的字母顺序排序。
这可能吗?
是的,这是可能的。图表选项在这里:

一个例子:
library(plotly)
library(dplyr)
# Dummy data
df <- data.frame(Product = c('Kramer', 'George', 'Jerry', 'Elaine', 'Newman'),
Patients = c(3, 6, 4, 2, 7))
# Make alphabetical
df <- df %>%
arrange(Product)
# Sorts legend largest to smallest
plot_ly(df,
labels = ~Product,
values = ~Patients,
type = "pie",
textfont = list(color = "white")) %>%
layout(legend = list(x = 1, y = 0.5))
# Set sort argument to FALSE and now orders like the data frame
plot_ly(df,
labels = ~Product,
values = ~Patients,
type = "pie",
sort = FALSE,
textfont = list(color = "white")) %>%
layout(legend = list(x = 1, y = 0.5))
# I prefer clockwise
plot_ly(df,
labels = ~Product,
values = ~Patients,
type = "pie",
sort = FALSE,
direction = "clockwise",
textfont = list(color = "white")) %>%
layout(legend = list(x = 1, y = 0.5))
