#2542: Support for creating and saving 1D histograms

 Reporter: Wolfgang Kastaun
   Status: new
Milestone: 
  Version: development version
     Type: enhancement
 Priority: minor
Component: Carpet

Comment (by Roland Haas):

Instead of just offering a signle type of reduction \(historgram\) it might be nicer \(and not more work\) to allow users to supply a custom “kernel” that is being called for each grid point by CarpetReduce. Something like:

```
int callback(cGH* cctkGH, CCTK_INT idx, CCTK_REAL data, void *calldata)
```

or so which would let users implement their own histogram or other reductions, eg. a maximum location reduction.
