Histogram buckets ignoring requested bucket size / not appearing

### What happened? I created a histogram with a bucket count of 33 (because there are 32 possible values), bucket size of 1, and an offset of 0 so the graph appears something like this:  <img width="469" height="204" alt="Image" src="https://github.com/user-attachments/assets/3880743f-37d2-42ff-be3a-89788eb12422" /> But when I look at a different time range, the bucket size changes, which makes the data more confusing to look at. I want the buckets to stay at a size of 1.  And if I change the time range again, then nothing appears and there's no x-axis?  ### What did you expect to happen? I would expect the histogram to look like the first screenshot. I want to see how many of each shutdown codes (1-32) were issued during the time range. ### Did this work before? It works when the time range is set to "last 2 days" or more.  ### How do we reproduce it? 1. Create a dashboard with a histogram panel using InfluxDB_SODA. 2. Configure 4 devices that are tracking shutdown codes. ### Is the bug inside a dashboard panel? | Key | Value | |--|--| | Panel | histogram @ 11.3.1 | | Grafana | Grafana v11.3.1 (9225f4a1cb) // Open Source | <details><summary>Panel debug snapshot dashboard</summary> ```json { "panels": [ { "id": 2, "type": "histogram", "title": "Reproduced with embedded data", "description": "", "gridPos": { "h": 13, "w": 15, "x": 0, "y": 0 }, "fieldConfig": { "defaults": { "custom": { "stacking": { "mode": "normal", "group": "A" }, "lineWidth": 3, …
