Histogram: Elasticsearch histogram panel not graphing data as expected

### What happened? I tried creating a histogram using the Elasticsearch data source, grouped by `bytes`: <img width="1003" alt="image" src="https://github.com/grafana/grafana/assets/7947184/adef2ee5-b675-41f8-8af2-bd93347d148d"> This is querying an Elasticsearch 8.13.2 cluster. The histogram shows 2 series (count and bytes). `count` seems to be graphing the number of buckets, while `bytes` is just `1`:  ### What did you expect to happen? I expected that the histogram would show something like this, which was created in Kibana: <img width="1418" alt="image" src="https://github.com/grafana/grafana/assets/7947184/c0790422-8910-400b-bc89-a4c5fdd74868"> In fact, the table view in Grafana suggests that the data is returned in the buckets as I would expect, but it's not being graphed correctly for some reason, possibly user error: <img width="1011" alt="image" src="https://github.com/grafana/grafana/assets/7947184/5582f990-fbb3-4e25-9b1b-eddae011586b"> ### Did this work before? Not sure ### How do we reproduce it? 1. Spin up an elasticsearch cluster using docker 2. Add the sample web log data using the Kibana integrations 3. Create a histogram grouped by `bytes` ### Is the bug inside a dashboard panel? | Key | Value | |--|--| | Panel | histogram @ 10.4.2 (22809dea50455ae875624827dd277b17621b4ed4) | | Grafana | 10.4.2 (22809dea50455ae875624827dd277b17621b4ed4) // Enterprise | <details><summary>Panel debug snapshot dashboard</summary> ```json { "panels": [ { "type": "histogram", "title": "Reproduced with embedded data", "gridPos": { "h": 13, "w": 15, "x": 0, "y": 0 }, "datasource": { "type": "grafana", "uid": "grafana" }, "id": 2, "targets": [ { "refId": "A", "datasource": { "type": "grafana", "uid": "grafana" }, …
