The date histogram facet is very useful, but does not collect variances or
standard deviations, only averages.
Seems simple enough to add (see e.g. the statistical facet, though should
probably use http://www.johndcook.com/standard_deviation.html instead); I'm
just not sure if the best approach is to create yet another facet plugin,
or add this to the existing facet and create a pull request?
if you need this is as a facet, it makes sense to write your own plugin.
But maybe this is already supported by aggregations, coming in 1.0 (and
already included in the current 1.0 beta release). Might make sense to take
a look there first, before starting to write your facet code. See

probably use Accurately computing sample variance online instead);

But you can try it in the new beta if you like. To my knowledge, the
feature is not complete yet and must be going through bug fixing but it
will give you a fare idea about how useful will this be for your use-case.
