Re: [matplotlib-devel] Code review request: minor modifications to axes.boxplot

Ben,

Thanks for the reply. I definitely like your idea. Seems like we could
include some logic in axes.errorbar to look at the shapes of xerr and
yerr in a similar fashion to what I propose for axes.boxplots,
allowing the user to have custom lower and upper errors for each data
point (in a time series as I would use it).

I'll try to bang that out this weekend while this is still fresh.
-p
