How should users reorder the x axis bins in a bar chart?

[briandk]

This is a classic question in ggplot2 for R.

Here's a simple reproducible example in python. This code:

from ggplot import *
p = ggplot(aes(x = 'cut', y = 'carat'), data=diamonds)
p = p + geom_bar()
p

Produces this bar chart:

If I wanted to reorder the bins (by count, in this example)

diamonds.groupby('cut').count().sort(columns=['carat'], ascending=False)['carat']

so that they appeared in this order from left-to-right in the plot

cut
Ideal        21551
Premium      13791
Very Good    12082
Good          4906
Fair          1610
Name: carat, dtype: int64

how would I do that?

Currently I think there is no way to do that. See #196, which is basically the same problem.

We probably need to have a workaround until pandas-dev/pandas#7217 is implemented in pandas and probably a fallback until we can depend on such a pandas version :-(

Hit this one too :(

For what it's worth, pip install -U to the github development version and specifying labels=list_of_label_names to geom_bar worked perfectly. So maybe this should be closed?

Yes. Thanks for the update!

I started chipping away at #283 have already incorporated pandas-dev/pandas#7217. So it will be changing sometime in the future.
