I don't think that helps. How can I specify apriori the number of bins and the min and max? AFAICT, the above would let me do this by forcing in some fake data, that has the effect of filling the cache and thus setting num_bins, min, max, but is has the side effect of causing that data to effect the histogram - which is not what I need.
Unless I misunderstand, we need another (simpler) class "histogram" that implements just this simpler behavior. Perhaps density could be build on top of it? It would indeed be nice to be able to explicitly specify the min and max for the bins and I guess that should not be too hard to do. Eric, what do you think? Sounds reasonable. I'm super-busy at the moment getting proto ready for its upcoming review. I can add this to the list, or someone (Neal?) can submit a patch which I would gladly accept.
I haven't gotten it working - I haven't learned about boost::parameter yet. Someone familiar with that could probably finish this quickly. Here is what I have so far: <snip>
I took Matthias' suggestion above to mean he thought the density accumulator could be given additional "min" and "max" constructor parameters, not that we need a whole new accumulator. Matthias, was that what you were suggesting? I'd rather go that route. -- Eric Niebler Boost Consulting www.boost-consulting.com
