Hello together

There is another try as a png file. Hope you can see it now, what i want to do with my bar chart.

Your example with ggplot2 works, but it wont help to convert my data like this one:

                                1           2              3                  4
abnr2                     11425   11425     11555         11888
TIME                       2            1              1                  2
Cat                          1            2              1                  2

to:

                            11425   11555      11888
1                          2            1               0
2                          1           0                2

Thanks for your help

The image did not come through. The list strips off most attachments to reduce the chance of virus or malware.

I "think" a png file will get through.

Anyway I still don't quite understand you but does this look like what you want?  Note I made a slight  change in the data.frame to use ggplot2.  If you want to try out the ggplot2 code you will need to install ggplot2 --use the command install.packages("ggplot2") to do so.


Also note that dd is a data.frame rather than your matrix. Again done for ggplot2

##==================================#
dd  <-  structure(list(x = 1:4, abnr2 = c(11425, 11425, 11555, 11888),
        time = c(2, 1, 1, 2), cat = c(1, 2, 1, 2)),
                    .Names = c("x", "abnr2", "time", "cat"),
                    row.names = c(NA, -4L), class = "data.frame")

  barplot(dd$abnr2, col= c("red","blue","red","blue"))

  library(ggplot2)
  p  <-  ggplot(dd, aes(x =  x, y = abnr2, fill = as.factor(cat)   )) +
                    geom_bar(stat = "identity", position = "dodge") +
                     xlab("Something")

Hello John,



thanks for your comment.

Your code is the way my matrix look like, yes.

What i want to do is, that each equal abnr2 is represented in the same bar.

Like the picture:



So in the end, i have a PDF, which contains for each abnr2 one bar.

If there are one abnr2 with 2 different kind of „cat“ (like 11425) i want to distinguish this difference in the color.



Simplified revealed, it should be look like this one:





Thanks for your help.

Mat

Is this what your matrix looks like?

mat1  <-  structure(c(11425, 11425, 11555, 11888, 2, 1, 1, 2, 1, 2, 1, 2), .Dim = c(4L, 3L), .Dimnames = list(NULL, c("abnr2", "time",

"cat")))

It is good practice to use dput() to supply sample data.



It is not particularly clear what you want to do. You apparently have four entries in the matrix and say that you want to have three bars.



How do you want to handle the 11425 value since it has diffference cats?
