How can I rearrange the order of y-axis on cleveland dot plot?-CodePudding

I have a Table and I generated a Hallmark Cleveland plot to visualize the enrichment scores before and after applying my software. But how can I rearrange the order of my plot to look like this ? I was thinking to sum up scores of all statuses in each hallmark and plot the hallmarks in a descending order based on the sum of status scores. But I am not sure how to do it. T

The code is as follows

library(ggplot2)
ggplot(Table, aes(Table$`Enrichment Scores`, Table$Hallmarks))   
    geom_point(aes(color=Table$Status))   
    ggtitle("Hallmarks")   geom_line(aes(group = Table$Hallmarks))   
    geom_vline(xintercept = ES_cutoff, color = "blue", linetype = "dashed", size = 1)

CodePudding user response：

Using a little made-up data, you could use fct_reorder to reorder the hallmarks based on the distance of the scores for that hallmark from the cut-off.

library(tidyverse)

# Made-up data
df <- tribble(~hallmarks, ~scores, ~status,
        "a", 10, "x",
        "a", 12, "x",
        "a", 14, "x",
        "b", 30, "x",
        "b", 31, "x",
        "b", 32, "x",
        "c", 20, "y",
        "c", 22, "y",
        "c", 26, "y",
        "d", 40, "y",
        "d", 39, "y",
        "d", 41, "y",
        "e", 30, "y",
        "e", 40, "y",
        "e", 60, "y"     
) 

cut_off <- 30

df |> 
  group_by(hallmarks) |> 
  mutate(distance = if_else(min(scores) >= cut_off, 
                            min(scores) - cut_off, max(scores) - cut_off)) |> 
  ggplot(aes(scores, fct_reorder(hallmarks, distance), color= status))   
  geom_point(aes(color = status))   
  ggtitle("Hallmarks")   
  geom_line(aes(group = hallmarks))   
  geom_vline(xintercept = cut_off, color = "blue", linetype = "dashed", size = 1)  
  labs(y = "Hallmarks")
