Order categorical data in a stacked bar plot with ggplot2

Question

I have a matrix with the following entries:

dput(MilDis[1:200,])
structure(list(hhDomMil = c("HED", "ETB", "HED", "ETB", "PER",

1, 9, 1, 3, 7, 10, 5, 5, 2, 8, 8, 4, 1, 2, 2, 9, 7, 7, 9, 2, 
2, 9, 5, 7, 10, 7, 2, 1, 8, 1, 1, 4, 8, 5, 7, 7, 5, 5, 2, 2, 
2, 8, 1, 5, 7, 5, 8, 7, 1, 5, 5, 7, 4, 1, 1, 1, 7, 4, 1, 1, 2, 
5, 3, 3, 8, 9, 4, 5, 5, 5, 10, 5, 7, 8, 8, 5, 2, 9, 3, 5, 3, 
10, 3, 7, 4, 7, 1, 1, 5, 3, 1, 4, 4, 7, 1, 7, 8, 7, 4, 4, 1, 
8, 4, 3, 1, 1, 4, 2, 3, 9, 9, 2, 8, 2, 3, 2, 5, 5, 8, 7, 7, 4, 
1, 1, 1, 2, 5, 5, 2, 3, 4, 3, 7, 4, 1, 1, 7, 5, 1, 2, 9, 8, 5, 
7, 2, 7, 1, 5, 5, 5, 3, 10, 9, 7, 10, 9, 7, 8, 6, 7, 8, 4, 9, 
9, 5, 7, 2, 2, 2, 4, 4, 8, 1, 8, 5, 8, 1, 1, 5, 8, 1, 5, 9, 7, 
8, 5, 2, 7, 7, 10, 1, 10, 10, 8, 5, 4, 7, 7, 9)), .Names = c("hhDomMil", 
"kclust", "order"), row.names = c(NA, 200L), class = "data.frame")

I want to create a stacked bar plot like this one .

The only problem is, that I would like to have the order of the stacks to fit this (ETB,PMA,PER,KON,TRA,DDR,BUM,MAT,HED,EXP) - the order numbers in the matrix and I have also some aesthetic problems. I searched for a solution here but none of the ordering suggestions worked for me... :-\

1. How do I plot such a ordered plot?
2. How do I set up x so that each bar is "on" one number?
3. How do I seperate the bars - here I tried that with a white border...?
4. How do I print all kclust numbers in x?

Thanks a lot for your help! Dominik

UPDATE

Here is the code I used to draw my plot:

mycols <- c('#FFFD00', '#97CB00', '#3168FF', '#FF0200', '#FB02FE', \
'#CCFCCC', '#FE9900', '#98CBF8', '#00CCFF', '#00FD03') # Set milieu colors


ggplot(MilDis) +
 geom_bar(aes(kclust, fill=factor(hhDomMil), \
 colour=mycols), position='fill', binwidth=1, colour='white') +
 scale_fill_manual(values = mycols)

---

UPDATE 2:

That's how I did it now:

    mycols <- c('#3168FF', '#00CCFF', '#98CBF8', '#CCFCCC', '#00FD03',\
   '#97CB00', '#FFFD00', '#FE9900', '#FB02FE', '#FF0200') # Set milieu colors

    ggplot(MilDis) +
      geom_bar(aes(factor(kclust), fill=reorder(hhDomMil,order)),\
      position='fill') +
      scale_fill_manual(values = mycols)

With this result:

Thank you all for your help!

Answer 1

I see that you have an order column in your data frame which I gather is your order. Hence you can simply do.

p0 = qplot(factor(kclust), fill = reorder(hhDomMil, order), position = 'fill', 
       data = df1)

Here are the elements of this code that take care of your questions

1. How do I plot such a ordered plot? reorder
2. How do I set up x so that each bar is "on" one number? factor(kclust)
3. How do I seperate the bars?
4. How do I print all kclust numbers in x? factor(kclust)

I remember from a previous question of yours that the hhDomMil corresponded to different groups, and I suspect your ordering follows the grouping. In that case, you might want to use that information to choose a color palette that makes it simpler to follow the graph. Here is one way to do it.

mycols = c(brewer.pal(3, 'Oranges'), brewer.pal(3, 'Greens'), 
           brewer.pal(2, 'Blues'), brewer.pal(2, 'PuRd'))

p0 + scale_fill_manual(values = mycols)
