Thank you!


Here is a little example of reordering:

tibble(x = factor(sample(LETTERS,20)), y = sample(1:100,20)) %>% 
  ggplot(aes(x = reorder(x,-y), y = y)) +


That is a different way to reorder. I have used that but this is not what I want. Thanks!


Is this then what you are looking for?

tibble(x = factor(sample(LETTERS,10)), y = sample(1:100,10)) %>% 
# A tibble: 10 x 2
   x         y
   <fct> <int>
 1 A        99
 2 B        93
 3 Q        87
 4 Y        77
 5 Z        74
 6 S        71
 7 M        19
 8 H        17
 9 C        14
10 U         5


If you copy and paste the code above, the data frame is completely different from yours.

I plot two columns on my data frame against each other in a stacked bar.

Your data frame or plot basically does not plot 2 variables against each other.

If you want, like I said, copy and paste my code above and run it. Try to use reorder() and see it yourself.



@Leon's point is still correct: reorder is the tool for the job. You just have to use it before the gather step.

 df8e %>% 
  mutate(ITEM_CATEGORY_DESCR = reorder(ITEM_CATEGORY_DESCR, Total_PL_Sales)) %>%
  gather(Buckets, value, -ITEM_CATEGORY_DESCR) %>%
  ggplot(aes(x = ITEM_CATEGORY_DESCR, y = value, fill = Buckets)) +
  geom_col() +


Thanks! I appreciate your help.


Great that you solved your challenge!

I would however for future reference recommend to downscale and simplify your examples. If the example is unnecessarily complicated, it takes focus from the technical challenge, for which you're seeking input - Hence my intentional use of small "dummy" tibbles. Also, appreciating the solution to the specific technical issue and then applying it to your particular challenge, imho increases the learning yield :slightly_smiling_face:


I used dput(data[1:5,]) and there are still tons of information coming out of that command.
I did not know what else I could do to limit down the sample size.
