Any news about OCA? This is the thing that blocks us from going forward
with this patch :)

The patch looks OK. I have a few comments though:

 a) Utils.loopOver can be simplified;

 b) There is no need to emit empty "rawDataHistogram". If some data is
not available, it's best to avoid printing out special values, like
empty array.

 c) The grouping is incorrect: it adds up histograms from different
iterations. This happens because the code reuses the old loop that
prints out *scalar* per each iteration. But in histogram case, you have
to wrap it up one more time.

Hopefully fixed all three here:

Can you look into it, and verify it still works as intended?

Thanks,
