Even though I'm familiar with the boxplot source code, I largely use
IPython for quick investigations like this.
In IPython, doing something like "matplotlib.Axes.boxplot??" shows the full
source code for that functions\.
Then I saw/remembered that boxplot now just calls
matplotlib.cbook.boxplot_
Uh, now I understand why it's behaving this way. Tx Paul.

How may I go about searching for the responsible code on my own in
situations like this?

I'm on python 2.
I get the same outputs after adding "from __future__ import division".

Your perturbed and unperturbed scenarios draw the same figure on my machine
(mpl v1.4.1).
The reason why you don't get any outliers is the following:
Boxplot uses matplotlib.cbook.boxplot_stats under the hood to compute where
everything will be drawn. If you look in there, you'll see this little
n
Are you running python 2 or python 3? If you're on python 2, what happens
if you add "from __future__ import division" to the top of your script?

Probably this change would upset John Tukey if he were alive.
I still wonder how you ignore the data since boxplot is there to represent
the data :)
Tell me how to undiff the changes then I will test your idea.

No - not the 'widths' kwarg. I want something that *looks* like the boxplot,
but for which I will have control of setting the ranges delimited by the box
and delimited by the whiskers (in the vertical dimension, not the horizontal
dimension). I resorted to hacking something from the existing code (

Hi -
yes - but I want something that looks like the generic boxplot, but in which
I can control where the edges of the boxes are placed what the sizes of the
whiskers are. A combination of errorbar and bar, with this appearance, if
you will.

Aren't those generically calculated from the data?

Hi - more generally, is there any way to control the location of the median
line, the vertical size of the box and the vertical location of the
whiskers?
Thanks - Ariel

Yep. I would like to pass in a list of lists, where each sublist (or array)
describes a boxplot to plot.
Meanwhile, i've been having fun with histograms. The Y axis labels are a
pain. I think defaulting to scientific notation, as matplotlib frequently
does, is annoying...

I'm still not sure I understand where the problem is:
You want several boxes in a plot ?
Something along the lines of what I already sent you ?

I agree. It may be common in matlab, but it really doesn't belong in
python.

Yeah, I agree, the situation is far from ideal. Besides, it turns out that

Use the "position" keyword, as a list of date ordinals (output of date2num).
Then, use
gca().xaxis_date(tz)
where tz is your current timezone (you can use None, that's easier).
