# Histogram Aggregation
> More info about histogram aggregation is in the [official elasticsearch docs][1]
A multi-bucket values source based aggregation that can be applied on numeric values extracted from
the documents. It dynamically builds fixed size (a.k.a. interval) buckets over the values.
## Simple example
```JSON
{
"aggregations": {
"prices": {
"histogram": {
"field": "price",
"interval": 50
}
}
}
}
```
And now the query via DSL:
```php
$histogramAggregation = new HistogramAggregation('prices', 'price', 50);
$search = new Search();
$search->addAggregation($histogramAggregation);
$queryArray = $search->toArray();
```
