Stacked bar chart, reorder by total (sum up of values) instead of value ggplot2 + dplyr

Diego Moya

I need to stack ETT by band for each ISO3, plus reorder ISO3 by the total sum-up of the values in each ISO3. So far, the stack is working ok, but the reorder is the issue. The code is reordering by individual ETT values (instead of sum-up of ETT values). Here is my code

library(dplyr)
library(ggplot2)
library(ggsci)

Ex4 <- example %>% 
  ggplot(aes(x = reorder(ISO3, ETT), y =ETT,  fill = as.factor(band))) + 
  geom_bar(stat="identity")+theme_bw()+
  guides(fill = guide_legend(nrow=3, title="Bands"))+
  theme(legend.justification=c(1,0),legend.position = c(0.999,0.01), text=element_text(size=12))+
  theme(axis.text.x = element_text(size=10),axis.text.y = element_text(size=7))+
  coord_flip()+ scale_fill_igv()
Ex4

Here is a portion of the result so far

Here can the data be downloaded (to have an idea)

Here is the expected ISO3 order (see from the 5th ISO3)

Here is what I have tried so far

Tot <- example %>% group_by(ISO3) %>% summarise_all(.,funs(sum))
unmelt <- dcast(allc_b, ISO3 ~ band)
merge_2 <-merge(x = Tot, y = unmelt, by = "ISO3", all = TRUE)
merge_2[is.na(merge_2) ] <- 0
df <- data.frame(merge_2[,c(1:11)]) 
mdfr <- melt(df, id.vars = "ISO3")

resulting (doubling results because of ETT in melt):

The code

Ex4 <- ggplot()+
  geom_bar(data=mdfr, aes(x=reorder(ISO3, value), y=value, fill=variable), # here value contains ETT to be removed
           stat="identity", show.legend = TRUE)+
  as above
  #ETT in the melt helps to reorder but in the figure, values increase by double.

Any suggestion is very much welcome.

According to help("reorder"), reorder() takes a third argument FUN which is mean by default.

If this argument is explicitely given as sum, we do get the expected result:

library(dplyr)
library(ggplot2)
library(ggsci)

example_small %>%
  ggplot(aes(x = reorder(ISO3, ETT, sum), y = ETT, fill = as.factor(band))) +
  geom_bar(stat = "identity") + 
  theme_bw() +
  guides(fill = guide_legend(nrow = 3, title = "Bands")) +
  theme(legend.justification = c(1, 0),
        legend.position = c(0.999, 0.01),
        text = element_text(size = 12)) +
  theme(axis.text.x = element_text(size = 10),
        axis.text.y = element_text(size = 7)) +
  coord_flip() + 
  scale_fill_igv()

Reproducible data

After downloading the file example.csv from OP's Google Drive folder https://drive.google.com/drive/folders/1yCjqolMnwdKl3GdoHL6iWNXsd6yFais5?usp=sharing I have created a smaller sample dataset whose dput() can be posted on SO.

library(dplyr)
example <- readr::read_csv("example.csv")
example_small <- 
  example %>% 
  group_by(ISO3) %>% 
  summarise(total_ETT = sum(ETT)) %>% 
  top_n(10) %>% 
  select(ISO3) %>% 
  left_join(example)

Result of dput(example_small):

example_small <-
