Mikhail,

Have you tried sorting your dataframe according to the levels on the x-axis?

HTH, Thierry

To call in the statistician after the experiment is done may be no more than asking him to perform a post-mortem examination: he may be able to say what the experiment died of.

The combination of some data and an aching desire for an answer does not ensure that a reasonable answer can be extracted from a given body of data.

Onderwerp: [R] ggplot2: labels and breaks order does not match and I can't usescale_fill_identity

Hi,

I'm plotting a bar chart like this:

ggplot() +
geom_bar(data=res,aes(fill=f1,x=f2,y=y),stat="identity",position="dodge" )

f1 contains quite a few levels and the plot is really quite difficult to read when the order of bars on the graph and on the legend does not match.

This problem has been discussed recently here: http://www.nabble.com/ggplot2---legend-for-fill-coulours-td16235166.html and the solution was to use scale_fill_identity to manually define the order
of both the breaks and the labels.
This is however unsuitable for me (at least in the unmodified form), as this
is part of a script that does not know in advance how many levels there arae
in f1.

Is there a way round this problem?

Many thanks
Mikhail Spivakov
